Network & Systems Administrator

Your mission & challenges

• Network operations: Operate, maintain, and continuously improve the Gym network (Aruba switching and Wi-Fi, 100G backbone, firewalls) and keep it available and fast under continuous training load. React quickly to incidents and fix root causes.

• Segmentation & Zero Trust: Maintain and improve the separation between training cells and internal networks, and keep strengthening Zero Trust access controls.

• Traffic & performance: Use QoS and traffic engineering to prioritise training-data uploads to the cloud and keep latency-sensitive traffic flowing.

• Monitoring & capacity: Use and refine monitoring for the network and on-site systems, act on alerts, and plan capacity so problems and bottlenecks are found and resolved before they affect training.

• Systems administration: Support the administration of on-site Windows and Linux systems together with your colleagues, and step in on systems topics where you can.

• Automation: Improve day-to-day operations by automating repeatable network and system tasks with Ansible, Python, or PowerShell.

• On-site IT support: Be an approachable, visible contact for developers, engineers, and robot trainers, and share first-line support with your on-site colleagues.

• Devices & lifecycle: Provision and support workstations, laptops, and peripherals, handle local onboarding and offboarding, and keep device records accurate.

• Smart escalation: Judge what is yours to fix and what belongs with the HQ team, and hand it over with the right context. Coordinate with HQ on cross-site connectivity and security governance.

• Vendors: Work with network hardware vendors and service providers on equipment and maintenance.

• Documentation & process: Maintain topology diagrams, IP plans, VLAN tables, and runbooks. Follow and help refine central IT processes rather than building local workarounds.

• Growing with the Gym: Share configuration standards and operating experience as further NEURA Gym sites are set up.

What we can look forward to

• Degree in an IT-related field or completed IT apprenticeship (e.g. Fachinformatiker/in Systemintegration), with at least 3 years of professional experience in network operations

• Strong hands-on network skills: switching, routing, enterprise Wi-Fi, VLAN segmentation, and firewall configuration; Aruba/HPE experience is a plus

• Experience with high-throughput LAN environments and QoS

• Understanding of Zero Trust principles

• Experience with network monitoring and structured troubleshooting

• Scripting and automation experience (Ansible, Python, or PowerShell)

• An advantage: administration experience with Windows and Linux, and working knowledge of Microsoft 365 and Entra ID

• A structured, independent, and proactive way of working and the confidence to take ownership of the network

• A service-minded, calm, and analytical approach under operational pressure

• Fluent English, spoken and written (B2+)

• A relevant certification (e.g. ACCP, CCNA, CCNP, or Network+) is an advantage
