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.
