Full Stack Engineer - Elixir

Company Description

Agree.com is an innovative payments platform that leverages robust e-signature technology to seamlessly integrate money movement with contract management. We are redefining document processing through advanced AI and OCR while offering CFO-grade reporting, analytics, and automated AR solutions. Imagine the combined power of DocuSign and Bill.com—signatures and payments unified into one comprehensive platform.

We are an early-stage fintech startup that is backed by some incredible investors, like Better Tomorrow Ventures and Pelion Venture Partners.

We are excited to be expanding our founding team and are looking for a talented Full Stack Engineer to help us build and scale this FinTech rocket ship 🚀

Role Description

As a senior member of the engineering team, you will play a pivotal role in the design, development, and future-state of our platform. You will work directly with everyone on the team from the CEO to the CTO to the Head of Design. This role requires a deep understanding of both the frontend and backend, with a strong emphasis on delivering a seamless user-experience.

The ideal candidate is a founder-minded professional who brings FinTech and/or LegalTech experience and excels in Elixir development. They are not afraid to ask hard questions and challenge the status quo. They are passionate about pushing the boundaries of innovation. They are customer-obsessed and might even answer a support email or two.

Some day-to-day challenges may include:

• Working in a highly collaborative environment, making decisions critical to the growth and scalability of the platform and leading new feature development

• Building out rich end to end user experiences in the platform with test coverage — from Postgres to LiveView, all the way to React Query and Tailwind

• Demoing WIP at a weekly all hands meeting in front of the entire team (bonus points if you show a terminal window!)

• Staying on the cutting edge of OCR and LLM technologies and industry insights, helping to further build out our AI/ML stack

• Improving Postgres query times and general platform o11y (we use PromEx and Grafana)

• Building and improving our integrations with third-party APIs, like Stripe, Anthropic, Intuit, and friends

Our stack consists of a Elixir/Phoenix monolith with React and Tailwind on the frontend, using LiveView to bridge the gap between real-time collaboration and rich user experiences. We leverage proprietary models and LLMs for document extraction/processing and OCR. We run primarily on Fly.io and heavily utilize technologies like Postgres, Tigris (S3), Oban, Docker, and Github Actions.

Qualifications

• 5+ years of professional experience in full-stack web development, with an emphasis on robust back-end architectures.

• Proven track record in integrating third-party APIs and developing custom RESTful APIs to support scalable Elixir applications.

• Strong knowledge of back-end development using languages like Elixir or Ruby

• Hands-on experience with relational databases such as Postgres or MySQL, ensuring optimal data integrity and performance.

• Proficiency with modern frontend frameworks such as React (desired), Vue, or Svelte, along with solid HTML and CSS expertise to complement a back-end focus.

• Exceptional ability to tackle complex challenges and lead projects from conception through execution.

• Excellent communication skills paired with a meticulous approach to quality in software development.

• Bonus: Extensive experience with the Elixir/Phoenix/LiveView stack or integrating modern front-end frameworks within Phoenix LiveView.

• Bonus: Familiarity with vector databases or vector extensions like pg_vector.

• Bonus: Prior experience in the FinTech industry and/or expertise in integrating payment solutions like Stripe.
