About The Position

Ready to step up from merely managing systems to designing the future of our entire technology ecosystem? We're seeking X2 Senior Technical Architect to be the driving force behind our next generation of scalable, resilient, and innovative solutions, directly translating business strategy into technical reality. Do you possess the deep technical mastery to mentor a high-performing engineering team while navigating the complex trade-offs between speed, cost, and quality? We are seeking a visionary Senior Technical Architect ready to own and evolve our enterprise-wide DDaT technical strategy and architecture. You will be the defining authority, responsible for architecting highly scalable, secure, and resilient solutions that directly impact public service delivery. Lead technical governance, mentor high-performing engineering teams, and drive our complex digital transformation journey by translating national strategy into robust technical reality. The Digital & Data Services (DDS) directorate is at the heart of CCS's digital transformation journey, responsible for delivering modern, efficient, and user-centred digital services that support over £30bn of public sector procurement annually. We're building a world-class digital capability that will revolutionise how the public sector buys common goods and services. The team operates as a single, unified unit of 6 (and growing to 10), combining both Enterprise Architecture (EA) and Senior Technical Architecture expertise. While we leverage supplemental support from preferred partners, we always maintain control, with our architects establishing the guardrails and managing the strategic direction of their work.
