Freelance Senior AI Engineer

The role

You will help build an agentic ecosystem that reimagines a function of government. You will build working prototypes and turn them into patterns and code that other government teams can reuse.

What you will do

• Design and build prototypes that expose services to agents through APIs, MCP servers and agent-to-agent protocols.
• Design and build agentic systems end to end, including orchestration, tool integrations, and memory and state.
• Build guardrails, evaluations and monitoring to check agents act safely and correctly.
• Work with designers and researchers to test agent-led journeys with real users.
• Advise on technical feasibility, risks and standards, in plain language.
• Turn prototypes into patterns, documentation and code that other government teams can reuse.

Required qualifications

• Design and build prototypes that expose services to agents through APIs, MCP servers and agent-to-agent protocols.
• Design and build agentic systems end to end, including orchestration, tool integrations, and memory and state.
• Build guardrails, evaluations and monitoring to check agents act safely and correctly.
• Work with designers and researchers to test agent-led journeys with real users.
• Advise on technical feasibility, risks and standards, in plain language.
• Turn prototypes into patterns, documentation and code that other government teams can reuse.
• Able to work from the London office at least two days a week.

Nice to have

• Substantial software engineering experience, with recent hands-on work building LLM-based applications or agents.
• Strong knowledge of tool use, agent frameworks and orchestration, and protocols such as MCP, and API design.
• Practical experience with guardrails, evaluation, testing and monitoring of AI systems.
• Sound judgement on security, privacy and safety risks, including prompt injection and misuse.
• Comfort working in fast, uncertain early-stage work, and explaining technical trade-offs to non-technical people.

Before you apply

• Hiring process: application with CV and portfolio, initial screening call, technical interview (about 60 minutes), and ways of working interview (about 45 to 60 minutes).
