Job Title: Full-Stack Developer
Location: London, United Kingdom
Our client are an AI Start-Up looking to build Agentic Systems for the purpose of auditing and certification.
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 startup, precision and speed are paramount.
