IT System Administrator

• Administer and secure our IT environment: • You will administer and continuously improve our Microsoft 365 and cloud environment, including identity and access, devices, and tooling for collaboration and security. • You will operate our zero-trust and secure-access setup and investigate and follow up on security alerts. You will also maintain endpoint security, patching and logging. • You will manage office networks, printing and meeting rooms at both sites, together with local partners where needed. • You will make sure backup, monitoring and recovery are in place and tested. • Run IT operations and support: • You will run and mature our IT operations, including the service desk, onboarding and offboarding, device lifecycle and asset management, licensing, and incident, change and problem management. • You will be the go-to person for colleagues with IT questions. You will solve issues yourself or coordinate with vendors, and you will help raise digital literacy across the organisation . • You will manage key IT suppliers and service partners, and you will keep licensing and costs under control. • You will document systems, procedures and decisions so that knowledge does not live in one person’s head. • Protect what matters: • You will support our information security function in policies, access reviews, risk assessments, vulnerability management, audits and security incidents. • You will ensure that systems, data storage, and remote and vendor access comply with export control requirements (EU dual-use regulation) and with the integrity and traceability expectations of a safety-critical environment. • Automate and grow: • You will replace manual work with scripted and repeatable solutions, using PowerShell, Intune and Entra configuration, and increasingly infrastructure as code. • You will support the IT side of engineering platforms, such as CAD and version control systems, simulation and data environments, and secure environments for AI tools. You will work together with the people who build and use them. • This is a role where success depends on reliable, secure systems and satisfied colleagues in a fast-moving engineering environment, not on perfect designs. ]]> • You enjoy owning an environment end to end, from fixing a laptop to tightening a conditional access policy, and you are motivated to make things more automated and secure each month. • You bring: • 3 to 10 years of experience in system administration or IT engineering, ideally in a growing, technical or regulated organisation . • Strong hands-on experience with Microsoft 365, Entra ID and Intune, and working knowledge of cloud computing. • A solid grasp of security fundamentals, including identity and access management, endpoint security, patching and zero-trust principles. • Scripting skills in PowerShell, or comparable skills in Python or Bash. • Fluency in English. • Experience with the following is a plus: infrastructure as code, Git, CI/CD and HCP. So is experience in nuclear, defense, aerospace or other export-controlled or safety-critical industries, and knowledge of Dutch or French. • Beyond technical skills, how you work is critical: • You work with openness: you make assumptions explicit, document what you build, and engage constructively with disagreement. • You take responsibility: you own problems end to end and do not depend on perfect organisational clarity to act. • You contribute to unity across teams: you serve colleagues across disciplines and both sites, and you explain technology in plain language. • You are pragmatic: you choose solutions that fit a ~50-person company with a credible path to scale, and you avoid unnecessary complexity. • What makes this role unique: • You will be the hands-on owner of the IT environ
