Are you a Senior or Tech Lead Software Engineer who loves solving infrastructure challenges through code?

We're recruiting for an experienced Python Software Engineer to join a significant government technology project, helping to build secure enterprise customer platforms used by critical organisations. This is an opportunity to work on complex cloud infrastructure, automation, and platform engineering challenges where your work will have a direct impact on the success of a high-profile programme.

Unlike many infrastructure roles, this is a genuinely software engineering-focused position. You'll spend your time building automation frameworks, developing internal tooling, creating Infrastructure as Code solutions, and eliminating manual processes through clean, scalable, production-quality code.

What You'll Be Doing

• Building automation frameworks and tooling using Python
• Developing Infrastructure as Code solutions with Terraform
• Creating reusable templates and code generation platforms using Jinja2
• Automating Windows environments through PowerShell
• Managing and improving configuration management with Puppet
• Building CI/CD integrations for infrastructure delivery
• Working closely with cloud, platform and engineering teams to improve automation and operational efficiency
• Driving infrastructure standardisation, reliability and scalability across complex environments

What We're Looking For

• Strong commercial Python development experience
• Experience building automation tools, frameworks or platforms
• Terraform and Infrastructure as Code experience
• Experience with AWS cloud services
• Puppet configuration management experience
• CI/CD and DevOps automation experience
• Passion for engineering best practices, testing and code quality
• Experience working in cloud and hybrid infrastructure environments
