Are you a Technical Lead Software Engineer who loves solving infrastructure challenges through code?

We're recruiting for a Technical Lead Software Engineer to join a significant government technology programme, helping build secure, large-scale 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.

• 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

• 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

The process is lean, friendly, and all hosted via MS Teams. There will be 2 interview stages lasting approx 2 hours in total.

• No external coding tests. No presentations. No trick questions. Quick turnaround.
• Interviews are happening in July and August. Start dates from 0-3 months depending on your availability.
