Full Stack Engineer

Job Title: Full-Stack Developer

Location: London, United Kingdom

Type: Permanent

Our client are an AI Start-Up looking to build Agentic Systems for the purpose of auditing and certification.

This role would be full time on-site and wouldn't be able to sponsor visas.

Responsibilities:

Build, test, and ship high-quality, high-velocity code across the full stack (front-end,

back-end, and AI-agent infrastructure).

Collaborate directly with the co-founders to solve complex architectural problems, like how to capture an auditor's "tribal knowledge" into a self-improving, agentic system.

Go beyond simple prompting: You will use LLM coding tools as a partner, understanding how to negate their weaknesses and build robust frameworks around them to maximize your output.

Get hands-on with our first design partners, understand their real problems (not just what they ask for), and build solutions that they will actually use.

The Ideal Candidate

BSc in Computer Science or relevant subject

A sophisticated user of LLM tools (e.g., Claude Code, Cursor, etc.) for coding - you understand their strengths, weaknesses, and how to build systems that leverage them effectively.

Candidates can use whatever language they feel most comfortable in but ideal would be Python/React alongside heavy usage of an AI coding tool such as Claude
