We're looking for a Systems Engineer / Technical Architect to help us reimagine a function of government as part of an agentic ecosystem.
You'll join a small multidisciplinary team of designers, researchers and engineers, working closely with civil servants and the department's own technical teams.
You'll own working out what the new system is. What are the constituent pieces, how do they fit together, and what’s needed to make it secure, accountable and auditable? The role suits someone who can sketch a target architecture on Monday and make it real with a prototype by Friday.
In this role you will:
Design the target architecture based high-level requirements and constraints, agentic capabilities and best practices
Recommend approaches to new challenges such as delegated authority and permissions
Set out security, resilience and threat risks and mitigations, including agent-specific risks such as prompt injection and automated abuse
Design and build the components that make the system accountable and auditable, such as audit logging and permission checks
Identify and test the riskiest technical assumptions
Build working prototypes and PoCs with the engineers
Produce clear architecture decision records, diagrams and patterns that teams can reuse
Engage with the client’s architects, security and assurance experts to get input and agreement on the right approach
Set out a realistic path from prototype to delivery
KEY SKILLS AND EXPERIENCE
MUST HAVES:
Significant experience as a technical or solution architect working on complex, ambiguous problems
A strong background in API design, integration patterns and event-driven or distributed systems
Deep knowledge of how agents interact with other parts of the system; tools, MCP servers, agent-to-agent protocols etc
Experience designing for security, privacy, observability and auditability from the start including threat modelling
Experience of authentication and authorisation, including delegated access, such as OAuth
Hands-on coding skills, with the ability to build working prototypes quickly
Cloud architecture experience (AWS, Azure or GCP) and infrastructure as code
The ability to explain architecture clearly to designers, policy specialists and senior stakeholders
NICE TO HAVE:
Experience in working on UK government services
Exposure to data-sharing standards and legislation, such as the Digital Economy Act
An agency or consultancy background
