Job summary

Nearfield Instruments in Rotterdam is seeking an IT Operations Engineer to run and improve internal IT operations with a strong focus on Microsoft 365, Active Directory, Windows Server, and security operations.

This role sits at the intersection of reliability and security: you’ll standardize how we operate, improve observability through monitoring tooling, and build pragmatic security playbooks that make incident handling faster and more consistent.

Qualifications

• 5+ years in IT operations / systems administration roles.
• Strong hands‑on experience with Microsoft 365 administration (core services + identity).
• Strong Active Directory + Group Policy administration experience (permissions, OU design, policy hygiene).
• Solid Windows Server experience (patching, roles/features, troubleshooting, hardening).
• Experience with monitoring tools (infrastructure/app/service monitoring, alert tuning, dashboards, on‑call hygiene).
• Experience creating and maintaining security playbooks/runbooks (structured incident handling, triage-to‑resolution workflows).
• Demonstrable experience working in an environment with ISO/IEC 27001 (controls, evidence, audits, risk treatment, policies).

Responsibilities

• Own day-to-day IT operations across Microsoft 365 (Exchange Online, Teams, SharePoint/OneDrive, Entra ID/Azure AD).
• Administer and harden Active Directory and Windows Server (GPO, patching, RBAC/permissions, baseline configs).
• Manage endpoints and policies (e.g., Intune, device compliance, conditional access, Windows update rings).
• Improve operational visibility: implement and tune monitoring/alerting for core services (identity, endpoints, servers, key business systems).
• Build and maintain security playbooks (incident response runbooks, triage steps, containment actions, escalation paths).
• Support vulnerability and patch management: tracking, remediation coordination, and evidence capture.
• Own operational hygiene: documentation, runbooks, change control, and repeatable processes.
• Handle escalations: troubleshoot authentication, access, policy, endpoint, and service issues end-to-end.
• Contribute to ISO 27001 practices: controls implementation support, evidence gathering, audits, and continuous improvement.
