Python Software Engineer

We’re looking for an experienced Senior Python Software Engineer with a strong background in cloud platforms and platform engineering to join a nationally critical programme supporting the UK’s healthcare infrastructure.

You’ll be working on a highly available, secure healthcare integration and messaging platform that forms part of the UK’s Critical National Infrastructure (CNI). The platform enables the secure exchange of patient and workforce data between healthcare organisations and digital services, helping ensure vital healthcare systems remain resilient, secure and available.

This is an opportunity to work on software that has a genuine impact on millions of people while helping shape engineering standards across a modern cloud-native platform. What You’ll Be Doing

Key responsibilities include:

• Developing high-quality, secure Python applications for complex distributed systems
• Maintaining and improving code quality across the platform
• Building, managing and monitoring CI/CD pipelines and code quality gates
• Ensuring deployments meet technical, security and governance standards
• Provisioning and supporting cloud-native infrastructure, primarily within AWS
• Collaborating with product teams to help build observable, reliable cloud-native services
• Supporting incident investigation and driving continuous platform improvements
