What you’ll be doing:

  • Configuring and running Kubernetes environments for scalable, resilient deployments
  • Designing and building CI/CD pipelines that make releases faster and safer
  • Supporting both on-premise and cloud infrastructure, keeping it consistent through automation and Infrastructure as Code
  • Implementing monitoring and alerting to keep platform services healthy and performant
  • Managing source control and repository tooling across teams
  • Leading automation work that removes manual effort and improves reliability
  • Advising development teams on platform best practice
  • Improving the platform’s security, supportability and scalability as it grows
  • Keeping on top of new tools and techniques and bringing the useful ones in

Experience you’ll need:

  • 5+ years in Platform Engineering, SRE, DevOps or a similar role
  • Strong hands-on Kubernetes configuration and container orchestration
  • Monitoring experience with Prometheus, Grafana or similar
  • Solid Git and repository management skills
  • A track record of automation that made a measurable difference
  • Clear communication and comfort working across teams
  • A degree in Computer Science or Engineering, or equivalent experience
  • Cloud experience (AWS, Azure or GCP) is a bonus

Because of the nature of the work, you must be a UK National and eligible for SC clearance. Holding active SC is a strong advantage.
