Job description

Deployable communications are the part of an alliance nobody sees until they fail. This role sits at third line behind one of those systems: the core services layer — virtualisation, directory, mail, name resolution, endpoint management and backup — that everything else on the mission network depends on.

It is hands-on engineering rather than ticket triage. You would be configuring, integrating and validating the kit before it deploys, keeping it healthy once it does, and writing the documentation that lets the next engineer pick it up cold.

What You Would Be Doing

• Build, configure and validate the core services layer of deployable communications kits, and prepare them for operational handover.
• Run the VMware estate day to day — vSphere, ESXi, vSAN, NSX, update services — and the storage and backup that sit under it.
• Administer the Microsoft core: Active Directory and domain trusts, Exchange, DNS, group policy, software distribution and endpoint protection.
• Take third-line incidents and changes through to closure, with proper root-cause analysis rather than a restart.
• Keep the technical documentation, procedures and configuration records accurate and auditable.
• Report monthly on service performance against the agreed measures.

What you would bring

• At least three years in a comparable infrastructure role, with A+ or an equivalent qualification.
• Real depth in VMware vSphere — ESXi, vSAN, NSX, CLI scripting — and in Veeam backup and replication.
• Solid Microsoft server administration: Windows Server, Exchange, Active Directory, DNS, group policy, software deployment.
• Comfort with small SAN and iSCSI storage, and with endpoint protection tooling.
• Good written and spoken English — this is a job where the handover notes matter.

The work is on site in Brunssum, in normal office hours, with occasional planned night work when a change window demands it and roughly one trip a month to other European locations.
