About the company

Our client is a technology company.

The role

Raydar is recruiting for this role on behalf of our client. Take ownership of major product areas from concept through production as a hands-on full-stack engineer. Work across interfaces, backend services and infrastructure, collaborating with research and infrastructure colleagues and learning directly from end users. The position is an early-team seat with real influence on product and technical direction.

What you'll do

- Own new product areas end to end, from first prototype to production release.

- Build across the full stack, including interfaces, backend workflows, AI model orchestration and supporting infrastructure.

- Turn emerging AI capabilities into dependable, intuitive products.

- Speak with users regularly, learn how they work and iterate quickly on their feedback.

- Prototype rapidly and make sound product and technical decisions.

- Help shape the product, the technical architecture and the team culture.

Requirements

What we're looking for

- Strong engineering skills combined with good product judgment and taste.

- A history of launching customer-facing software that gained real adoption, ideally built from scratch.

- Comfort working across product, engineering, models and infrastructure rather than in one narrow specialty.

- Evidence of exceptional ownership, such as founding a company, leading a major product or delivering consequential work at a leading technology company.

- High agency, speed, ambition and a founder mentality.

- Approximately 3 to 6 years of applied or product engineering experience, with exceptional candidates at other levels welcome.

- Comfort in a very early, fast-moving, self-directed environment.

Bonus points

- Experience at a company building AI-driven products.

- Early-team or founder experience.

- Standout achievement in a competitive field such as programming or math olympiads, quantitative work or elite competition.
