The Role

We're looking for a Technical Lead with proven industry experience in digital product delivery and architecture to join our team. You will be an expert collaborator and technical communicator with a structured, hands-on approach to breaking down complex technical architectures and data structures.

In this role, you will lead the technical pathfinding for a key cross-system data initiative with the Ministry of Justice (MoJ). You will excel at working collaboratively within a multidisciplinary Rainbow Team alongside Delivery Managers, Software Engineers, User Researchers, and Product Designers to build technical proofs-of-concept (PoC) and operational prototypes. Acting as the technical authority, you will work closely with government system owners and SMEs to understand integrations, map technical flows, and establish a shared data foundation that directly empowers frontline users.

Skills and Experience Required

• Technical Design & Architecture: Proven experience creating both high-level conceptual designs and detailed, low-level technical designs for engineering teams to deliver on.

• Feasibility Assessment: Ability to conduct technical feasibility assessments of candidate architectural approaches, defining clear constraints and outlining recommended paths from concept to implementation.

• Government Standards Alignment: Understanding of how to design and build solutions that comply with government digital, data, and technology standards, security controls, and data governance.

• Agile Pathfinding & Prototyping: Experience working within an Agile, test-and-learn environment to rapidly validate technical assumptions, de-risk delivery, and break candidate solutions into deliverable components.

• Stakeholder & SME Engagement: Strong written and spoken communication skills, with the ability to confidently engage with senior leaders, system owners, and technical SMEs to resolve complex technical unknowns.

Technical Experience and Tooling

• API & Integration Patterns: Hands-on experience working with APIs, complex data access patterns, identity resolution services, and managing integration constraints across fragmented Legacy systems.

• End-to-End Data Flow Mapping: Proven expertise in designing and documenting secure technical workflows, specifying exactly how data moves, where business logic sits, and how role-based access control is applied.

• Vetting Requirements: Candidates must hold Security Check (SC) clearance.
