Senior Software Engineer (Python, FastAPI, React, AWS)

We’re looking for a senior engineer, who can own and drive complex projects end-to-end. You’ll be responsible for designing and building key product features, coordinating work across functions, and making thoughtful technical tradeoffs with minimal oversight. You should be comfortable taking a loosely defined problem, shaping it into a clear plan, and executing quickly.

This is a hands-on technical role. You’ll spend most of your time designing systems and writing code. You thrive in ambiguity, ask the right questions, figure things out independently, and have a strong “get stuff done” mindset without needing much hand-holding.
