Job Description

Global Software Solution Provider, support the UK Government's most critical national security missions. Their UK infrastructure team is expanding and hiring engineers now.

The role:

  • Build, operate and maintain high-performance, scalable, reliable services across UK Government deployments
  • Own production reliability: monitoring, alerting, configuration management and upgrades
  • Lead automation to reduce manual operations, using modern platforms including LLM/AI tooling
  • Deploy new products into production and run infrastructure migrations
  • Shape systems design alongside forward deployed and product teams

What you'll need:

  • UK SC clearance, or eligibility to obtain it (active SC strongly preferred; no visa sponsorship)
  • 1-5 years in infrastructure engineering or SRE, building and deploying production systems - not just debugging
  • Hands-on Kubernetes/Docker in production; Terraform, Ansible or CI/CD pipeline experience
  • Proficiency in Java, Python, Go or JavaScript, applied to infrastructure or operations
  • Distributed systems, Linux and cloud (AWS/GCP/Azure) experience
  • CS or computer engineering degree
  • Comfortable balancing build work with operational support - this is a build-and-run role
  • Backgrounds in defence tech, tech-forward defence contractors, or security cleared cloud/infra teams

The package:

  • excellent salary, bonus and share scheme
  • Hybrid London working with 1-2 days from home
  • Small UK team, big remit, and genuine ownership from day one
