We are hiring a Software Engineer to join the founding technology team behind a new AI-enabled equity hedge fund.

This is an early-stage build within an established investment business, giving you the pace and ownership of a start-up with the backing and infrastructure to build properly.

You’ll work directly with engineering, quantitative research and investment teams, building technology that has a real impact on the investment process.

What you’ll be building

  • Research applications, stock screeners and investment workflows
  • Backend services, APIs and data pipelines
  • Production AI and LLM-powered applications
  • AI agents, retrieval and document-processing workflows
  • Cloud-native, scalable production systems

What we’re looking for

  • 3+ years of commercial software engineering experience
  • Strong Python experience in production environments
  • Experience with C#, Java, Go or another strongly typed backend language
  • Strong API, backend and data engineering fundamentals
  • Experience with cloud, containers and modern engineering practices
  • An interest in LLMs, AI agents and building production AI systems

Previous hedge fund experience isn’t required. We’re looking for strong engineers who are curious, pragmatic and want to build.

If you want genuine ownership and the opportunity to work at the intersection of software, AI and investing, we’d like to hear from you.
