## Description

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.

## Requirements

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.
