Senior System Admin

We’re hiring an IT Operations Engineer to run and continuously improve our 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.

You’ll work closely with engineering and business stakeholders to keep systems stable, secure, and compliant.

Nearfield Instruments (NFI) is a fast-growing scale-up high-tech company. We design, develop, integrate, market and service advanced metrology machines. Our machines enables our customers - the world’s leading chipmakers – to increase the production yields, and thus, functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics.

Founded in 2016, we bring together the most creative minds (approx. 380 employees) in science and technology and develop a one-of-a-kind, revolutionary high throughput Scanning Probe Microscopy system.

• Demonstrable experience working in an environment with ISO/IEC 27001 (controls, evidence, audits, risk treatment, policies).

• Entra  features:
  Conditional Access, PIM, identity protection, MFA strategy.

• Familiarity with Microsoft security tooling.

• Automation skills.

• Experience with ticketing/ITSM practices (incident/problem/change management).

• Basic networking knowledge (DNS, routing concepts) for troubleshooting identity/service issues.

• Experience with Palo Alto products (Prisma / Cortex / Strata).

• Experience with Zabbix.

• Stable, predictable IT operations with fewer recurring issues and clearer ownership.

• Improved security posture through enforceable baselines, least privilege, and high patch compliance.

• Monitoring that’s actionable (less noise, faster detection, better dashboards).

• Security playbooks that reduce incident time‑to‑contain and create consistent outcomes.

• ISO 27001 readiness: clean evidence trails, clear controls ownership, and continuous improvement.
