Container & Unix Administrator

Join a dynamic and growing IT software and systems provider at the forefront of secure, high-performance infrastructure. You’ll work on a highly specialised, air-gapped container platform in a defence-sector environment, tackling complex technical challenges that few professionals get to experience. This is your chance to advance your career, from hands‑on administration to senior‑level responsibilities and strategic influence. All this while contributing to critical, high-security operations.

• Work in a highly secure, air-gapped environment with cutting-edge technologies.
• Join a varied technical environment spanning containers, Kubernetes, Unix/Linux, and automation.
• Unlock a clear path from junior to senior responsibilities, with opportunities to shape architecture and platform operations.

• Contribute to CI/CD processes, documentation, and compliance with security policies
• Participate in incident, change, and problem management
• Take on increasing responsibility over time, including architecture decisions and platform optimization
• Senior candidates: expected to perform independently across all areas
• Junior/mid-level candidates: expected to learn, grow, and gradually take on these responsibilities
