The role:

On behalf of a central government client, we're looking for an experienced Head of Technical Architecture to lead to lead architecture across the development of AI-enabled digital products used directly by the public.

This is a senior technical leadership role requiring someone who can hit the ground running, with a strong track record of building and releasing digital products at national scale. Experience delivering public-facing AI products and agentic solutions is particularly important, including managing safety risks, implementing guardrails and conducting red teaming or other threat assessments.

Key requirements:

• Extensive experience as a Technical or Solutions Architect, with a strong background in digital product development rather than enterprise architecture or back-office systems.
• Proven experience building and shipping user-facing digital products, including websites or applications, with clear examples of ownership across multiple major releases.
• Hands-on experience delivering AI-enabled products, ideally including AI agents deployed directly to end users.
• Experience scaling digital products to national audiences, ideally supporting tens of thousands of concurrent users.
• Strong technical leadership experience, including managing architecture teams and multiple architects.
• Strong AWS experience, ideally including serverless technologies and Amazon Bedrock.
• Experience establishing AI guardrails, managing safety risks and conducting red teaming or threat assessments.
• The successful candidate must hold SC clearance before starting.

Experience with agentic development, AI evaluation, secure-by-design principles, NCSC guidance, the Cyber Assessment Framework (CAF), privacy and user experience management would be advantageous. AWS certifications or a computer science qualification would also be useful, but practical experience is more important.

If you have the technical leadership experience and AI architecture background required, please get in touch with your latest CV.
