About the job

Job title: Senior Full Stack Engineer

Job description:

• Own the development, maintenance, testing, and operations of a full-stack application. The backend is primarily Elixir/Phoenix/Absinthe and hosted in GCP. The frontend is React, primarily TypeScript with some legacy JavaScript still being converted.
• Collaborate cross-functionally with our product manager, designer, other engineers, etc. to understand our users’ problems, design and build solutions to those problems, and validate our work.
• Build and maintain the application throughout the product life cycle.
• Take ownership and be empowered to make key decisions about what we build and how we build it.
• Grow as an engineer and assist those around you in their growth via mentorship, pairing, code reviews, and so on.
• Use LLMs (we use Claude and Codex) as part of your workflow, while owning the output, applying your own judgment, and keeping full understanding of what ships.

Salary range: USD $140,000–$170,000 per annum

Qualifications or experience required:

• 6+ years of backend software development experience, with 3+ of those in a functional language. Elixir or Erlang experience strongly preferred.
• 3+ years experience in React
• Self-directed and capable of working effectively in a startup environment
• Able to design data models and architect software solutions that consider both performance and future maintainability in a large, existing codebase
• Very communicative and responsive, as we work from home

What the successful job applicant will be working on: Full stack web development. We’re a relatively small team (7 engineers), so there’s an opportunity to have a lot of impact and cut across the entire stack.
