About the company

Our client is a fast-growing financial technology company.

The role

Raydar is recruiting for this role on behalf of our client. Join a small engineering group as an early hire with significant autonomy, building backend services and tooling for an AI-driven software product while also supporting existing core platform systems. The work is hands-on and mostly backend, with some exposure to frontend development.

What you'll do

  • Build and extend the set of tools an AI agent can use to complete multi-step business tasks.
  • Improve the quality, breadth and depth of the agent's capabilities so it delivers dependable end-to-end results.
  • Combine existing tools and create new ones, such as email drafting, document completion and third-party account integrations.
  • Contribute to the shared infrastructure that supports the company's other business lines.
  • Own delivery from the start, ramping up quickly and working in a fast-moving, AI-assisted development workflow.

What we're looking for

  • Between new graduate level and 5 years of engineering experience.
  • A strong background signal, such as time at a notable startup or large technology company, or a degree from a top computer science program.
  • Solid Python backend fundamentals, including APIs, async programming, databases and cloud deployment.
  • Daily use of agentic coding assistants, with well-formed views on how to make agent-based systems better.
  • A self-motivated, tech-lead-style approach: quick to ramp up, able to work with minimal guidance and comfortable with ambiguous scope.

Bonus points

  • Full-stack experience, including TypeScript on the frontend.
  • Zero-to-one startup experience with demonstrable users.
  • Background in high-frequency trading or quantitative engineering.
  • Genuine interest in user experience and product, not only systems.

Location and work model

  • New York City, NY, United States
  • On-site (in-person)
  • Full-time

Compensation, as the posting describes it

  • Equity
