Job summary

Insight International (UK) Ltd in the United Kingdom is seeking a senior engineering leader to drive a pod migrating AWS Lambda applications to Azure. You will design the harness, define scaffolding, and own CI/CD guardrails to keep agent-generated code coherent.

You will lead a small, high-output team, reporting migration velocity and risk to stakeholders while mentoring engineers on prompt-driven multi-agent orchestration and architecture enforcement.

Qualifications

• 8–10 years software engineering experience.
• 4+ years leading delivery teams.
• Deep AWS and Azure serverless experience.
• Hands-on Claude Code, Claude Desktop and Cowork proficiency.

Responsibilities

• Lead and evolve the engineering pod for cloud migrations.
• Decompose the AWS estate into migration work-packages with clear criteria.
• Enforce architectural invariants with automated tests and linting.
• Run periodic entropy-management sweeps to maintain coherence.
• Mentor engineers on prompt-driven discovery, multi-agent orchestration, and tooling.
• Report migration velocity, agent utilization, and risk to stakeholders.

Job description

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

• 8-10 years software engineering; 4+ years leading delivery teams
• Deep AWS and Azure serverless experience (Lambda -> Functions, DynamoDB -> Cosmos DB,Step Functions -> Durable Functions)
• Hands-on Claude Code, Claude Desktop, and Cowork proficiency
• Track record of building developer tooling, CI/CD pipelines, or platform engineering
