Every login, every certificate, every name lookup. Somebody has to build that foundation properly.

A multinational defence organisation in Brunssum is delivering new communication and information systems, and it needs a senior engineer to take the core services from design through to a clean handover - directory, identity, certificates and the Windows infrastructure underneath them.

What you would be doing

• Producing technical designs for core services and turning them into working, tested installations
• Installing, configuring and integrating Active Directory, Group Policy, DNS, DHCP, certificate services and federation, including hybrid identity with Entra ID
• Running testing and acceptance, then supporting deployment and migration into live service
• Writing the technical documentation that goes with every build
• Spotting risks early, contributing to quality assurance and keeping project governance informed
• Reporting regularly on progress, milestones, issues and next steps

What you would bring

• At least 5 years designing, implementing and deploying enterprise infrastructure and core services, ideally with a degree in computing or engineering
• Strong Active Directory, Group Policy, PKI and Windows Server engineering
• Virtualisation (VMware vSphere or Hyper-V), enterprise storage and backup, high availability and disaster recovery
• Infrastructure as Code and automation with tools such as Terraform, Ansible or PowerShell DSC, plus CI/CD and Git
• A security-first mindset: hardening, privileged access and certificate-based authentication
• Experience in large government or defence environments is a strong plus, as are Microsoft, VMware, Terraform or security certifications

Why this one is worth a look

It is the layer every other system depends on, built from the design stage rather than inherited, inside a long-running international programme.
