Agentic AI Architect

Nexify Infosystems; Greater London; On-site; GBP 110,000 - 160,000; Full time

Job summary

Nexify Infosystems in Greater London seeks a seasoned software engineering leader to guide a small, high-output pod through the migration of AWS Lambda applications to Azure. Your focus is on designing the harness, setting scaffolding, constraints, and feedback loops that enable Claude Code agents to work reliably.

You own CLAUDE.md specs, enforce architectural invariants with automated tests, linting, and dependency checks, and mentor engineers in prompt-driven TDD and multi-agent workflows.

Qualifications

• 6-8 years of software engineering experience.
• 2+ years leading delivery teams.
• Hands-on Claude Code, Claude Desktop, and Cowork proficiency.

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).
• Run weekly entropy-management sweeps using Claude Code tasks to maintain codebase coherence.
• Mentor engineers on prompt-driven TDD and multi-agent orchestration, Claude Desktop / Cowork workflows.
• Report migration velocity, agent utilisation, 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

• 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
