Founding Software Engineer

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.
