About the Role

We are looking for a Mid-Level Full Stack Developer to join our engineering team. In this role you will design, build, and maintain web applications across the full technology stack, working closely with product owners, designers, and fellow engineers to deliver reliable, scalable solutions. You will contribute to both greenfield features and the ongoing improvement of existing systems, with meaningful ownership of the code you ship.

Key Responsibilities

• Design, develop, and maintain backend services and RESTful APIs using C# / .NET (including ASP.NET Core and Entity Framework).

• Build responsive, user-friendly front-end interfaces with Vue.js, HTML5, CSS3, and JavaScript/TypeScript.

• Collaborate with product owners and UX designers to translate business requirements into well-architected technical solutions.

• Write clean, testable, and well-documented code; participate in code reviews and uphold team coding standards.

• Integrate with third-party APIs, payment platforms, and external vendor systems.

• Troubleshoot and resolve production issues across the full stack, including database and infrastructure layers.

• Contribute to CI/CD pipelines, automated testing, and deployment processes.

• Participate in Agile ceremonies (stand-ups, sprint planning, retrospectives) and contribute to continuous process improvement.

Required Qualifications

• 3–5 years of professional experience in full stack software development.

• Strong proficiency in C# and the .NET ecosystem (ASP.NET Core, Entity Framework, Web API).

• Hands-on experience with Vue.js (Vue 2 or Vue 3) or a comparable modern JavaScript framework (React, Angular).

• Solid understanding of relational databases (SQL Server preferred) including writing optimized queries and understanding stored procedures.

• Experience with RESTful API design, versioning, and consumption.

• Familiarity with Git-based version control workflows (branching, pull requests, code reviews).

• Working knowledge of HTML5, CSS3, and responsive design principles.

• Bachelor’s degree in Computer Science, Software Engineering, or a related field — or equivalent practical experience.

Preferred Qualifications

• Experience with SOAP/WCF service integrations or XML-based data exchange.

• Familiarity with unit testing frameworks (xUnit, NUnit, MSTest) and mocking libraries (Moq, NSubstitute).

• Exposure to cloud platforms (Azure preferred) and containerization (Docker).

• Knowledge of CI/CD tooling such as Azure DevOps, GitHub Actions, or Jenkins.

• Experience working in telecom, fintech, or payments-related domains.

• Understanding of code quality tools (SonarQube / SonarCloud) and static analysis practices.

• Experience with AI/ML development, including working with LLMs, prompt engineering, AI-powered features, or integrating AI APIs (e.g., OpenAI, Azure AI Services).
• Bilingual in English and Spanish preferred.
