About the role
- We are looking for a Senior Full Stack Engineer to join the early team and help define how money moves on Fin.
Responsibilities
- Design, build, and ship full stack features across our web and mobile surfaces, from APIs and services to polished user interfaces.
- Own projects end to end: work with product and leadership to scope requirements, design systems, implement, test, and ship to production.
- Build scalable, high performance services that handle real money movement with strong reliability and observability.
- Maintain a high bar for code quality through clean abstractions, tests, and thoughtful code review.
- Collaborate closely with product, design, and operations so that what we ship feels simple for users even when the underlying system is complex.
- Clear written and verbal communication, and an ability to work closely with non engineering partners.
Requirements
- Deep experience with TypeScript and Node.js.
- Production experience with React Native.
Benefits
- Bonus points if you are familiar with the Expo ecosystem and modern mobile build pipelines.
Company info
