About the role

What You'll Work On

  • Core backend services and APIs
  • Product surfaces that finance teams rely on daily
  • Interfaces and tools that simplify complex concepts for internal and external users
  • Internal systems that improve reliability, observability, and performance

Engineers partner closely with Product and Design through quick conversations, whiteboard sessions, and collaborative problem solving.

What We Care About

You'll thrive if you:

  • Enjoy owning systems end-to-end, from first design doc to fixing production edge cases
  • Care deeply about correctness and long-term maintainability
  • Are curious about domains you don't already understand, and are willing to sit with discomfort while you learn
  • Can disagree respectfully, explain your reasoning, and change your mind when the data says you should

We're optimizing for excellent engineers who are good teammates.

We don't care as much about:

  • Exact years of experience
  • Whether you're "frontend" or "backend" by title
  • Whether you've worked in fintech before

If you've built scalable systems, shipped real software, and learned from breaking prod, we want to talk.
