Description du poste

Microsoft infrastructure is easy until it has to be secure, federated and audited. Then it needs someone like you.

You would provide the senior Microsoft engineering for a multinational defence organisation in Mons, Belgium — designing, building and running the enterprise platform and the identity services on top of it, through the whole of their life.

What you would be doing

• Designing, configuring, operating and troubleshooting complex Microsoft enterprise infrastructure in secure environments
• Carrying Windows Server platforms and their services end to end: architecture, deployment, hardening, patching, upgrade, migration, monitoring and decommissioning
• Designing and administering Active Directory — domains, forests, trusts, group policy, authentication, DNS integration and the identity infrastructure around it
• Being the expert on identity and access: authentication, authorisation and federation, including AD FS, Entra ID and open-source stacks such as Keycloak
• Building and maintaining public key infrastructure, certificates and everything that depends on them, including lifecycle and trust
• Running on-premise SharePoint environments — site architecture, permissions, metadata, taxonomy, search, content management and integration
• Designing secure integrations with the rest of the estate, including the Atlassian stack, Power BI, Splunk and SQL Server
• Supporting the cloud reference environment and the pipelines behind it: source control, automated deployment, continuous integration and delivery, configuration management
• Automating with PowerShell and infrastructure as code so the work is repeatable
• Keeping it all inside the security requirements and hardening standards, remediating what reviews turn up
• Advanced troubleshooting and root-cause analysis, and the incident, problem, change, configuration and release processes around it
• Advising on where the platform should go next — technology, resilience, availability, scale

What you would bring

• At least six years designing and running Microsoft enterprise infrastructure at medium to large scale
• Strong hands-on Windows Server and Active Directory, with group policy and DNS, plus federation and single sign-on through AD FS and Entra ID
• Real depth in PKI, certificates, TLS and certificate lifecycle
• SharePoint from installation through security, integration and lifecycle, plus Microsoft 365 and hybrid environments
• Practical Azure and hybrid cloud, with pipelines and infrastructure automation
• Strong PowerShell; Python, SQL and infrastructure-as-code such as Terraform or Bicep are a plus
• SQL Server and the enterprise plumbing around it — networking, firewalls, proxies, load balancing, high availability, backup and recovery
• Troubleshooting complex failures, hardening, patching, upgrades, migrations and vulnerability remediation
• Working inside IT service management, and writing documentation someone else can follow
• A technical degree with a substantial IT component, plus four years in exactly this kind of work — or, exceptionally, ten years of progressive expertise in it
• Professional English

Nice to have

• Microsoft certification in Azure, identity, Windows Server, Microsoft 365 or SharePoint
• Security, service management, DevOps or cloud architecture certifications
• Work for military, governmental or other security-sensitive organisations, and on mission-critical services
• Integrations with Jira, Confluence, Bitbucket, Splunk or Power BI
• Endpoint configuration manager, Exchange or web application proxy

Why this one is worth a look

Identity and certificates are where the real engineering is, and here they carry a security weight most enterprises never see.
