• Proven delivery of GDS-aligned services through Beta
• Experience in ASP.NET Core APIs and modern web architectures
• Ability to operate as both technical lead and senior engineer
• Strong understanding of cloud-hosted platforms and CI/CD pipelines
• Experience mentoring developers and leading agile teams
• Previous public sector or Local Authority engagement
• UK-based

Summary of the Best Candidate
