The Role
We’re hiring a Senior Full-Stack Engineer to own the front end and carry real weight on the back end of a subscription SaaS product in the financial space. It is live, paid for, and used daily, with gated premium content, an AI assistant, and data-heavy dashboards. The front end is Next.js with React and TypeScript. The back end is Python microservices on FastAPI with PostgreSQL on AWS. You’ll live mostly in the first and be expected to move confidently in the second.
We are an AI-first engineering team Claude Code, Codex and Cursor are part of how we ship, not an experiment on the side. This is a hands-on senior role on a small team. You’ll take a feature from a spec conversation to production yourself, and you’ll talk directly to client-side engineers while doing it.
We need someone who reads an existing codebase, takes ownership, and drives decisions not someone who waits for the next instruction.
