We’re supporting a pioneering technology team within one of the most technically sophisticated and financially successful firms operating today. They’re scaling a lean but high-impact engineering unit that builds internal tooling and platforms used across everything from People Ops to Investment Research.

The Opportunity

They’re looking for a seasoned React Developer to take real ownership of frontend projects — working on high-visibility platforms used by internal stakeholders across the business. You’ll collaborate closely with product-minded engineers and UX designers in a flat, remote-first team known for delivering fast, thoughtful iterations.

What Makes This Different?

  • Ownership: You’ll be trusted to lead feature development, manage iterations, and engage directly with end-users.
  • Autonomy: The team thrives on independence — no micromanagement, just trust and delivery.
  • Engineering Depth: You’ll join colleagues with backgrounds in Big Tech, all of whom understand React beyond surface-level usage.
  • Impact: While the core remit focuses on business process tools, the team is steadily branching into more investment-facing and AI-driven initiatives.

What They’re Looking For:

  • ~5+ years of professional software development experience
  • ~ Deep understanding of React – not just how to use it, but how it works under the hood
  • ~ Comfortable working across the stack (reading backend APIs, collaborating closely with backend teams)
  • ~ A pragmatic approach to engineering and a strong sense of product ownership
  • ~ Bonus points for previous experience in lean or remote-first engineering environments
  • ~ An in-depth Github portfolio

If you’re looking to join an elite team where you can make real impact, work with smart and humble engineers, and avoid bureaucracy — this is the one to explore.
