Rails Developer Resume Examples and Templates
Junior Rails Developer Resume Example and Template
What's this resume sample doing right?
Strong measurable impact in work history
Your experience lists clear metrics that show impact, like raising test coverage from 58% to 82% and reducing API response time by 25%. Those concrete numbers match what BrightLeaf Labs wants for performant backend work and help recruiters see your results fast.
Relevant technical skills and tools
You list key Rails technologies used on real projects: RSpec, Capybara, Sidekiq, Devise, Pundit, PostgreSQL, and GitHub Actions. Those tools map directly to tasks a Junior Rails Developer will do and help your resume pass ATS keyword checks.
Hands-on experience with APIs and backend design
Your notes about building JSON APIs, refactoring controllers into service objects, and MVC design show you know backend patterns. BrightLeaf Labs looks for clean code and maintainable services, and your examples show you follow those practices.
How could we improve this resume sample?
Summary could be more targeted
Your intro is solid but generic. Tailor it to BrightLeaf Labs by naming clean code, performance tuning, and test-first development. Tie one short sentence to a recent achievement, like the coverage improvement, to boost relevance.
Skills section lacks depth for ATS
Your skills list is good but brief. Expand it with specific gems, testing tools, CI/CD items, caching, and deployment tech (Redis, Puma, Docker, AWS). That raises ATS match rates and tells hiring managers which tools you actually use.
Resume structure and contact links could be clearer
The experience descriptions include HTML lists that may confuse some ATS. Use plain bullet lines in a single-column layout and add direct links to your GitHub and deployed projects. That makes parsing easier and shows your code directly.
Rails Developer Resume Example and Template
What's this resume sample doing right?
Strong quantification of impact
Your resume uses clear numbers to show impact, like "250K monthly active users" and "API response time from 820ms to 220ms (73% improvement)". Those metrics make it easy for hiring managers to see you built scalable Rails systems and solved real performance problems.
Relevant technical skills and tools
You list core Rails stack skills such as Ruby on Rails, PostgreSQL, Redis and RSpec. Your experience using Sidekiq, Prometheus and Grafana matches backend observability and jobs expectations for a Rails developer role at scale.
Evidence of quality and team leadership
You show a focus on testing and mentorship: RSpec coverage rose from 48% to 88% and you mentored six juniors. That tells recruiters you drive code quality and help teams deliver, which matters for senior Rails roles.
How could we improve this resume sample?
Condense HTML in experience descriptions
Your role descriptions use HTML lists. That can confuse some ATS parsers and makes quick skims harder. Convert to simple plain-text bullets and start each bullet with a strong action verb for clearer ATS and recruiter reading.
Expand skills and keyword coverage
Your skills list is solid but short. Add CI/CD tools, container tech, API styles, and testing tools like Docker, Kubernetes, GitHub Actions, GraphQL or REST, and ElasticSearch. That boosts ATS hits for Rails backend roles.
Add a concise, tailored summary line
Your intro is strong but a one-line summary with target keywords would help. Start with a 1-2 sentence headline that mentions "Ruby on Rails, performance tuning, and scalable APIs" so recruiters immediately see the fit.
Mid-level Rails Developer Resume Example and Template
What's this resume sample doing right?
Effective use of quantification
You use numbers to show impact throughout the experience section. Examples include reducing API response time from 420ms to 160ms and cutting batch windows from 6 hours to 90 minutes. Those metrics prove you deliver measurable backend performance gains, which matters for a Mid-level Rails Developer focused on performance.
Strong test-driven and CI focus
Your intro and experience highlight RSpec, Capybara, and CI pipeline work. You state 92% coverage and automated pipelines that cut failed deploys by 75%. That shows you write tests and improve reliability, which matches the job need for test-driven development and deployment stability.
Relevant Rails backend skills and keywords
Your skills list and role details include Ruby on Rails, PostgreSQL, Sidekiq, Redis, Docker, and Kubernetes. Those keywords align with typical ATS searches for Rails backend roles. Your work on microservices, ActiveRecord optimization, and background jobs reinforces the match.
How could we improve this resume sample?
Make the summary more specific to the role
Your intro reads well, but you can tighten it to match the job. Add the Rails versions you use, CI tools like GitHub Actions or Jenkins, and specific performance targets you achieved. That helps recruiters and ATS see an exact fit quickly.
Add a clear technical tools section
Your skills show core items, but list them in a compact tools section. Include Redis, Nginx, Sidekiq, RSpec, Capybara, Docker, Kubernetes, and CI systems by name. That improves ATS matching and helps hiring managers scan your stack instantly.
Show links to code and projects
You mention strong engineering work but have no GitHub or portfolio link. Add a GitHub link and one or two feature PRs or performance write-ups. That gives proof of your code, and it helps interviewers validate your Rails skills quickly.
Senior Rails Developer Resume Example and Template
What's this resume sample doing right?
Clear quantifiable impact
Your resume lists concrete metrics like "throughput 3x", "response time from 420ms to 120ms", and "CI coverage from 58% to 88%". Those numbers show real impact and match the senior engineering focus on performance and reliability employers look for.
Relevant technical skills and tools

Your intro lists strong experience but stays broad. Tighten it to show one or two top outcomes that match the job, such as improving deploy velocity or building highly available APIs, so hiring managers see the fit immediately.
Skills section can use more keywords
Your skills list is solid but brief. Add specific keywords like ActiveRecord tuning, Rails Engines, Docker, CI/CD (e.g., GitHub Actions), and monitoring tools. That boosts ATS hits and speaks to the workflow and deployment improvements in the job description.
Make achievements scannable for ATS and hiring managers
Experience descriptions use HTML lists, which is fine visually. Still, add 1-2 short bullet-line summaries at top of each role with the core achievement and tech used. That makes impact quicker to scan and better for parsers that prefer plain text bullets.
Lead Rails Developer Resume Example and Template
What's this resume sample doing right?
Clear impact with numbers
You quantify outcomes across roles, which helps hiring managers quickly see your impact. Examples include reducing dashboard load time from 2.8s to 0.9s, tripling deployment frequency, and increasing test coverage to 93%. Those metrics match what Atlassian would expect for a Lead Rails Developer.
Strong leadership and mentoring evidence
Your experience shows team leadership and growth. You led eight engineers, mentored colleagues on service extraction, and promoted four to senior roles. That proves you can coach developers and raise team velocity, a core duty for this lead role.
Relevant technical scope and tools
You list core technologies and show practical use of them. Rails, PostgreSQL, Sidekiq, and AWS appear in both skills and achievements, like migrating analytics to Postgres and using background jobs to cut load. That aligns with the job focus on scalable Rails architecture.
How could we improve this resume sample?
Summary could be more targeted
Your intro highlights experience and outcomes, but it reads broad. Tighten it to call out architecture, team size you want to lead, and specific problems you solve. Mention Atlassian-like scale or modules you want to own to better match the role.
Skills section lacks some leadership keywords
You list strong technical skills but miss leadership keywords employers search for. Add terms like "architecture review", "roadmap ownership", "stakeholder communication", and "technical hiring" to improve ATS hits and show senior ownership.
Few details on system design decisions
Your bullets show results but not design trade-offs. Add one-line notes about architecture choices, constraints, and alternatives considered. For example, why you chose read replicas or a particular job strategy. That shows deep system thinking.
Principal Rails Developer Resume Example and Template
What's this resume sample doing right?
Proven impact with measurable results
Your experience lists clear metrics that show real impact, like boosting availability from 99.85% to 99.98% and cutting DB costs by 32%. Those numbers make your achievements concrete and directly match a Principal Rails Developer role focused on reliability and cost reduction.
Strong architecture and modernization examples
You describe phased extraction of six Rails components and a 70% deploy time reduction. That shows you can modernize monoliths into services and deliver operational gains, which directly supports the job need for large-scale Rails modernization.
Good observability and platform practices
You highlight OpenTelemetry, Prometheus, Grafana, and an engineering-wide Rails performance playbook. Those items show you lead on observability and platform reliability, key responsibilities for the Principal Rails Developer role.
How could we improve this resume sample?
Summary could be more targeted
Your intro lists strong credentials but reads broad. Tighten it to name the exact outcomes you will bring to Shopify, like lowering p99 latency or enabling independent scaling. That makes your value immediate to hiring managers.
Skills section lacks tooling depth
You list core skills but omit specific tools and versions that ATS look for. Add details like Ruby versions, Rails versions, PostgreSQL features, Sidekiq scaling patterns, and cloud platforms used. That improves keyword match and credibility.
Work bullets need clearer role context
Many bullets show outcomes but not your exact scope and ownership. For each major result, state whether you led the effort, designed the solution, or coordinated cross-team work. That clarifies your principal-level leadership and decision authority.
1. How to write a Rails Developer resume
Applying for a Rails Developer position can be daunting, especially when you see so many resumes that look alike. How can you ensure yours stands out? Hiring managers want to see how you've applied your skills to real projects, not just a list of technologies you've used. Unfortunately, many applicants mistakenly focus on technical jargon instead of showcasing their tangible contributions.
This guide will help you craft a compelling resume that highlights your unique strengths and experiences. You'll learn how to transform generic job descriptions into impactful statements that reflect your achievements, such as detailing how you improved application performance by 30%. We'll also cover essential sections like work experience and skills. After reading, you'll have a resume that effectively communicates your value as a Rails Developer.
Use the right format for a Rails Developer resume
When crafting a resume for a Rails Developer position, the best format is typically the chronological one. This format highlights your work history and skills in a clear, organized manner. It works well for those with a steady career progression in software development. If you've changed careers or have gaps in your employment, consider the combination or functional format instead. These formats allow you to emphasize your skills over your work history.
Regardless of the format you choose, ensure your resume is ATS-friendly. Use clear section headings and avoid complex graphics or tables. Here’s a quick breakdown:
- Chronological: Best for steady career progression.
- Functional: Great for career changers or those with gaps.
- Combination: Useful for showcasing both skills and experience.
Craft an impactful Rails Developer resume summary
The resume summary is your chance to quickly grab the employer's attention. For experienced Rails Developers, a summary is ideal. If you're just starting out or changing careers, an objective statement might serve you better. A strong summary follows this formula: [Years of experience] + [Specialization] + [Key skills] + [Top achievement]. This structure helps you highlight your strengths effectively.
For instance, if you have five years of experience in Rails development, your summary should reflect that along with specific skills and a notable project you completed. This approach makes it easy for hiring managers to see what you bring to the table right away.
Good resume summary example
Resume Summary:
Rails Developer with 5 years of experience specializing in scalable web applications. Proficient in Ruby on Rails, PostgreSQL, and API development. Successfully led a project at Spinka that improved application load time by 30%.
Objective:
Aspiring developer with a focus on Ruby on Rails, eager to contribute to a dynamic team. Completed a Rails bootcamp and built several personal projects highlighting web application functionality.
These examples work because they clearly state experience and skills while showcasing a meaningful achievement or a proactive learning approach.
Bad resume summary example
Resume Summary:
I am a Rails Developer looking for a new opportunity. I hope to use my skills at a great company.
This summary fails because it lacks specific details about experience, skills, or accomplishments, making it too vague for potential employers.
Highlight your Rails Developer work experience
When listing your work experience, always put your jobs in reverse chronological order. Make sure to include your job title, company name, and dates of employment. Use bullet points to detail your accomplishments, starting each with a strong action verb. For a Rails Developer, you might use verbs like 'developed,' 'implemented,' or 'optimized.' Don't forget to quantify your impact when possible. Instead of saying 'Responsible for improving application performance,' say 'Optimized the application, resulting in a 40% decrease in load time.' This gives employers clear evidence of your contributions.
The STAR method (Situation, Task, Action, Result) can help structure your bullet points. Keep your descriptions concise and focused on achievements.
Good work experience example
Responsibilities:
- Developed a Rails application at Spinka that increased user engagement by 50% through optimized user interface design.
This works because it uses a strong action verb, specifies the company, and quantifies the result, showcasing the impact of your work.
Bad work experience example
Responsibilities:
- Worked on various Rails projects at Gerlach-Schultz.
This fails because it lacks specificity and quantifiable achievements, making it less impactful.
Present relevant education for a Rails Developer
In the education section, include the school name, degree, and graduation year. For recent graduates, you can make this section more prominent and include your GPA or relevant coursework. If you have significant work experience, this section can be less prominent, and you might omit your GPA. If you've completed any relevant certifications, consider adding them here or in a dedicated section.
Keep the formatting clean and straightforward. This makes it easy for hiring managers to find your educational background quickly.
Good education example
University of Technology, Bachelor of Science in Computer Science
Graduated: May 2018
GPA: 3.8
Relevant Coursework: Web Development, Database Management
This works well because it clearly states the degree, institution, and relevant details that showcase your qualifications.
Bad education example
Community College, Some courses in Computer Science
Not completed
This fails because it doesn't clearly indicate a degree or relevant completion, making it less valuable to potential employers.
Add essential skills for a Rails Developer resume

Use these impactful action verbs to describe your accomplishments and responsibilities:
Add additional resume sections for a Rails Developer
Consider including additional sections like Projects, Certifications, or Volunteer Experience. These can showcase your skills and dedication beyond work experience. Projects can highlight your coding skills and problem-solving abilities, while certifications demonstrate your commitment to ongoing learning. Including relevant languages can also set you apart in a competitive field.
Good example
Projects:
- Developed a personal finance tracking application using Ruby on Rails, allowing users to visualize their spending habits. This project received positive feedback from over 100 users.
This works because it details a specific project, highlights a skill, and shows user engagement.
Bad example
Projects:
- Worked on some personal coding projects.
This fails because it doesn't specify what the projects were or the impact they had, making it less effective.
2. ATS-optimized resume examples for a Rails Developer
Applicant Tracking Systems (ATS) are software tools that help employers manage the recruitment process. They scan resumes for keywords that match job descriptions, making it essential to optimize your resume for the Rails Developer role. If your resume lacks the right keywords or has formatting issues, the ATS might reject it before a human even sees it.
To boost your chances, follow these best practices:
- Use standard section titles like “Work Experience,” “Education,” and “Skills.”
- Incorporate relevant keywords from job descriptions, such as “Ruby on Rails,” “RESTful APIs,” and “JavaScript Frameworks.”
- Avoid complex formats like tables, columns, or images that ATS may misread.
- Stick to readable fonts like Arial or Calibri.
- Use common file formats, like PDF or .docx, and avoid fancy designs.
Common mistakes include using creative synonyms instead of exact keywords from job descriptions. Relying on headers or footers might also lead to ATS ignoring crucial information. Don't forget to include essential keywords related to skills, tools, or certifications that are relevant to the Rails Developer position.
ATS-compatible example
Work Experience
Rails Developer at Strosin
January 2020 - Present
- Developed and maintained applications using Ruby on Rails, enhancing user experience and performance.
Why this works: This example clearly states the role, company, and relevant technologies. It uses standard formatting and includes important keywords that ATS looks for.
ATS-incompatible example
My Previous Job
Worked at Gerlach and Keeling
- Created web apps using various technologies, including some programming languages.
Why this fails: The section title is non-standard, making it harder for ATS to categorize. The description is vague and lacks specific keywords like Ruby on Rails, which ATS needs to identify your fit for the role.
3. How to format and design a Rails Developer resume
When you're crafting your resume as a Rails Developer, choosing the right template is key. Aim for a clean, professional layout, preferably in a reverse-chronological format. This approach helps recruiters quickly see your most recent experience, which is crucial in tech roles where skills evolve rapidly.
Generally, one page works best for entry-level or mid-career developers, while more experienced candidates might need two pages to cover their extensive history. Just remember to keep it concise and focused, showcasing your relevant projects and skills without unnecessary fluff.
For fonts, go with professional options like Calibri or Arial in sizes 10-12pt for body text and 14-16pt for headings. Make sure there's plenty of white space to enhance readability. Avoid overly creative designs that could confuse applicant tracking systems (ATS) and human readers alike.
Common mistakes include using complex templates with multiple columns or graphics that can trip up the ATS. Excessive colors or non-standard fonts can hurt your professional appearance too. Lastly, ensure you have clear section headings to guide the reader through your qualifications.
Well formatted example
Beier Group
Rails Developer
January 2021 - Present
- Developed and maintained scalable web applications using Ruby on Rails
- Collaborated with cross-functional teams to deliver high-quality software solutions
This clean layout ensures readability and is ATS-friendly. Clear headings and concise bullet points make it easy for recruiters to spot key information.
Poorly formatted example
Lemke-Hand
Rails Developer | January 2021 - Present | Developed, maintained applications using Ruby on Rails, worked with teams to deliver high-quality solutions. |
- Implemented features
- Improved performance
ATS may struggle to parse columns, and the lack of clear spacing makes it hard for human readers to follow along. This format looks cluttered and less professional.
4. Cover letter for a Rails Developer
A tailored cover letter is essential when applying for a Rails Developer position. It complements your resume and shows genuine interest in the role and company. Employers want to see your enthusiasm and how your skills align with their needs.
Start with a strong opening paragraph. Clearly state you’re applying for the Rails Developer position, express your excitement about the opportunity, and mention a key qualification. This grabs attention right away.
In the body paragraphs, connect your experience to the job requirements. Highlight key projects you've worked on, specific technical skills like Ruby on Rails, and relevant soft skills such as teamwork. Use quantifiable achievements to demonstrate your impact. Tailor your content to the specific company and role by incorporating keywords from the job description.
- Header: Include your contact information, the company's details, and the date.
- Opening Paragraph: State the specific role, express enthusiasm, and mention a compelling qualification.
- Body Paragraphs: Showcase relevant experience, skills, and achievements.
- Closing Paragraph: Reiterate your interest, express confidence, and include a call to action.
Conclude by thanking the reader for their time. Maintain a professional yet enthusiastic tone throughout. Customize your letter for each application to avoid sounding generic.

5. Mistakes to avoid when writing a Rails Developer resume
Creating a resume for a Rails Developer role means you need to showcase your technical skills and project experience clearly. Common mistakes can undermine your chances of getting noticed by hiring managers. Paying attention to detail is essential for making a strong impression.
Let’s explore some frequent pitfalls that you should avoid when crafting your resume.
Avoid vagueness in technical skills
Mistake Example: "Proficient in web development."
Correction: Be specific about your skills. Instead, write: "Proficient in Ruby on Rails, HTML, CSS, and JavaScript with experience in building RESTful APIs and integrating third-party services."

Correction: Detail your contributions to specific projects. For instance, "Developed a customer management system using Rails that improved client onboarding efficiency by 30%." This shows your impact and role clearly.
Typos and grammatical errors
Mistake Example: "I have experience in developping Ruby applications."
Correction: Always proofread your resume. The correct version would be: "I have experience in developing Ruby applications." Use tools like Grammarly to catch errors.
Poor formatting for ATS
Mistake Example: Using unusual fonts and layouts that may confuse Applicant Tracking Systems.
Correction: Stick to a simple, clean format. Use standard fonts like Arial or Times New Roman, and clearly label sections like 'Experience' and 'Skills' to help ATS parse your resume effectively.
Including irrelevant information
Mistake Example: Listing outdated technologies or unrelated work experience, like "Worked as a barista for two years."
Correction: Focus on relevant experience. If you worked on a side project that involved Rails, mention that instead. Highlight skills that directly relate to the Rails Developer position.
