I’m currently supporting a major public sector digital programme that is looking for an experienced Senior Developer to join their engineering team. This is an opportunity to work on large-scale, meaningful services used across health and social care, contributing to both greenfield development and the modernisation of existing digital platforms.

The environment is collaborative, user-focused and aligned to GDS-style delivery, with an emphasis on open working, high engineering standards and transparent decision-making.

• Designing and building secure, reliable backend services in Python, following TDD and automated testing practices
• Developing front-end features using React and modern JavaScript / Type Script tooling
• Delivering cloud-native solutions on AWS, working with services such as Lambda, API Gateway, ECS and RDS
• Working closely with product, design, research and engineering teams in an agile, multidisciplinary setting
• Contributing to CI / CD pipelines, Dev Ops automation and infrastructure-as-code
• Participating in code reviews, technical discussions and continuous improvement initiatives
• Supporting open documentation and transparent version-controlled design choices
• Balancing new feature delivery with the ongoing improvement of existing services

• Strong hands‑on experience with Python for production services (FastAPI, Django or similar)
• Solid experience working with React and modern frontend development patterns
• Proven AWS capability, ideally across both serverless and containerised workloads
• Strong understanding of CI / CD, automated testing, code quality and Dev Ops practices
• Experience with in the public sector, GDS-aligned teams or large enterprise environments is highly desirable
• Ability to collaborate effectively within an agile, multidisciplinary team
• A focus on engineering quality, clear communication and user‑centred delivery

• Familiarity with the government design frameworks
• Experience with Terraform, CDK or other infrastructure-as-code tools
• Exposure to legacy technologies such as Java or .NET (not essential)

• The chance to work on highly impactful digital services used at national scale
• A mature engineering culture that values quality, transparency and continuous improvement
• A mix of modern greenfield work and meaningful transformation projects
• Flexible working and long‑term programme stability
