Senior Core Services Engineer (Active Directory, PKI, Windows Server) for NATO with security clearance

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.
