You will bring:

• Significant engineering leadership experience across complex digital services, ideally within UK Central Government or another regulated environment.
• A strong software engineering background and sufficient technical depth to command the confidence of senior engineers, architects and client technical leaders.
• Experience leading multiple engineering teams rather than only a single programme or product.
• Strong understanding of modern cloud engineering, DevSecOps, CI/CD, security, architecture and operational practices.
• Experience with GDS-style multidisciplinary delivery and an understanding of the Service Standard and Technology Code of Practice.
• Strong understanding of security and privacy by design.

• Strong consultancy skills and the ability to operate credibly with senior government stakeholders.
• Commercial awareness, including experience shaping work, estimating delivery and contributing to bids or proposals.
• The ability to balance technical quality, user outcomes, delivery constraints and commercial reality.
