Agentic AI Architect in London

London Full-Time No working from home possible
N

Need to have experience in handling big teams. You will lead a small, high-output agentic engineering pod migrating AWS Lambda applications to Azure.

Inspired by OpenAI’s Harness Engineering model, your primary job is not writing code — it is designing the harness: the scaffolding, constraints, and feedback loops that let Claude Code agents do reliable work. You own the claude_code_forge scaffolding, define CLAUDE.md specs, enforce architectural invariants, and build the CI/CD guard-rails that keep agent-generated code coherent. You are player-coach: 70% building harness, 30% guiding the pod.

Key Responsibilities

  • Own and evolve the claude_code_forge scaffolding — repo structure, CLAUDE.md templates, creating agents, MCP tool configs, and custom slash commands
  • Decompose the AWS estate into depth-first migration work-packages with clear acceptance criteria agents can validate
  • Enforce architecture mechanically (structural tests, linting rules, dependency-layer checks) rather than through documentation alone
  • Run weekly entropy-management sweeps using background Claude Code tasks to maintain codebase coherence
  • Mentor engineers on prompt-driven TDD, multi-agent orchestration , and Claude Desktop / Cowork workflows
  • Report migration velocity, agent utilisation, and risk to stakeholders

You Bring

  • 6-8 years software engineering ; 2+ years leading delivery teams
  • Hands-on Claude Code , Claude Desktop , and Cowork proficiency
  • Track record of building developer tooling, CI/CD pipelines , or platform engineering
