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

  • Fin is a next-generation payments platform built for high-value, global, and instant transactions.
  • We are a Series A-stage company backed by Sequoia, Circle, and other notable investors.
  • Powered by stablecoins, Fin enables users and businesses to move millions of dollars in seconds - whether to other Fin users, directly into bank accounts, or across crypto rails.
  • By combining the speed of crypto with the reliability and trust of traditional finance, Fin reimagines how money moves worldwide.
  • If banks and payment products were reinvented today, they would look like Fin.
  • We are mostly a TS shop with some pockets of Rust.
