Job Description:

Full Stack Product Engineer (Stealth AI Startup) ? London, UK (On-site, 5 days/week)

About the Role

Join a small, high-performing product engineering team at an early-stage AI startup (currently in stealth). As the third engineer on a close-knit London-based platform team, you’ll play a pivotal role in building and iterating on a powerful, user-facing platform from the ground up.

This is an opportunity to help define the architecture and direction of a product with the potential to reshape how AI is deployed in complex business environments. We’re building technology around cutting-edge AI workflows that require deep technical ownership and creativity.

What You’ll Do

• Build end-to-end product features across the stack (frontend, backend, data)
• Work closely with founders and engineers to ship fast, iterate quickly, and influence product direction
• Solve novel technical challenges related to scaling, performance, and usability
• Contribute to a product that leverages AI in practical, real-world workflows

You Might Be a Fit If You Have

• 3–7+ years of experience as a software engineer working on production-grade applications
• Expertise in at least some of our core stack: Python, FastAPI, React, Next.js, TypeScript, Postgres
• A product-minded engineering approach – you care about what gets built and why
• Experience building platforms or internal tools, ideally in a startup or fast-paced environment
• The ability to thrive in an early-stage environment: ambiguity, speed, and autonomy excite you

Why Join Us

• Be part of the foundational team at a well-funded AI startup
• Help define the product, engineering practices, and company culture
• Work closely with experienced founders from top-tier tech backgrounds
• Competitive salary and equity
• Work in-person with a team that values collaboration, speed, and innovation
