Job Title: AI Coding Engineer

Location: London, United Kingdom

Our client are an AI Start-Up looking to build Agentic Systems for the purpose of auditing and certification. This role is 100% on-site and wouldn't be able to provide sponsorship.

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:

• Exceptional technical talent with more than 2 years of professional experience.
• Your GitHub, personal projects, or hackathon wins speak for themselves.
• A first-principles problem solver. You have a fundamentally strong computer science background (e.g., from a top university or equivalent experience) and are language-agnostic, picking the right tool for the job.
• AI-Native: You are already 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.
• High-Leverage & High-Output: You thrive in a high-pressure, high-growth environment. You understand that in an early-stage start-up, precision and speed are paramount.
