What you'll need:

  • 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.
