Acting as the central point of contact for engineers within your area, you will ensure that solutions are sustainable and aligned with the Government Digital Profession strategy.

Working alongside other Senior, Lead, and Principal Engineers, you will ensure technical approaches are appropriate, consistent, and endorsed. You will also engage with senior stakeholders in planning activities to establish a robust foundation for product delivery and ongoing maintenance. While your remit spans the engineering function, you will collaborate closely with Architects and other professional disciplines to deliver secure, resilient, and future-ready systems.
