Job Description:

We are partnered with a well-funded, early-stage fintech building critical infrastructure for the digital assets industry.

  • Designing and integrating connections to financial data providers and banking APIs
  • Developing frontend dashboards in React that make complex financial data clear and actionable for clients

  • Helping establish engineering practices and standards from the ground up

What We’re Looking For:

  • Strong Python experience, ideally in data-intensive or financial applications
  • Solid full‑stack capability – comfortable across backend services and React frontends
  • High agency: you take ownership, move fast, and work well without hand‑holding
  • Comfortable in an early‑stage environment where requirements evolve
