Hire an AI Implementation Engineer, UK

An AI implementation engineer wires AI — coding agents, LLM tooling, automation — into the systems and workflows a company already runs, so it reaches production rather than staying a demo. I do this as contract or fractional work, available immediately, inside or outside IR35.

What you get

  • An audit of your current stack and workflows to find where agentic AI or LLM tooling actually earns its keep — and where it's theatre.
  • Hands-on implementation: wiring coding agents (Claude Code, Codex, Cursor and Kimi-class tools) into existing engineering workflows, with review and proof-of-work gates so output is trustworthy, not just fast.
  • A provider-agnostic setup — a multi-engine router and credential/quota broker pattern, so the team isn't locked to one vendor.
  • Adversarial cross-engine review built into the delivery process from day one — one model builds, a different model attacks the diff — catching production-class defects (SSRF, IDOR, auth gaps, races) that single-engine review misses.

Who it's for

  • Engineering teams that already have a codebase, CI and a review culture, and want AI implemented properly inside it.
  • Leaders who've watched a coding-agent pilot produce plausible-looking but unverified output, and want the guardrails rather than another demo.
  • Regulated or security-sensitive teams — fintech, payments — where "the agent said it worked" isn't evidence.

Who it's NOT for

  • Teams wanting an AI-strategy slide deck with no implementation attached — that's a different engagement.
  • A single canned tool install with no change to how work gets reviewed — that doesn't fix the reliability problem.
  • A full-time in-house hire — this is contract or fractional engineering, not a day-to-day staff seat.

How it runs

  • Starts with a scoped audit of the current stack and where agent-driven work would land.
  • Runs as a contract engagement, or a fractional arrangement for ongoing work — cadence agreed per engagement.
  • Delivered directly through Appaya Ltd, my own company — not resold through an agency.
  • Remote or London hybrid.
