Role

Senior Network Operations Engineer — Office Networking

Location: Utrecht

Workload: 36 hours per week

This is an operational squad role within an Agile team (not a project assignment), responsible for daily operations, service stability, changes, deployments, release testing, and continuous improvement for an HPE Aruba SD-Branch based office network delivering wired and wireless connectivity globally.

Responsibilities

  • Troubleshoot and resolve LAN, WiFi, SD‑WAN, and authentication-related incidents.
  • Perform structured root cause analysis on complex issues.
  • Handle service requests, operational tickets, and changes independently.
  • Interpret monitoring alerts and assess service impact.
  • Drive improvements in automation, monitoring, documentation, and reduction of recurring incidents.
  • Participate actively in Agile/Scrum ceremonies.
  • Communicate with stakeholders, regional IT teams, and end-users when needed.
  • Participate in an occasional standby/on-call rotation.

Must-have skills

  • Strong knowledge of routing and switching.
  • Good understanding of SD‑WAN architectures, including overlays and underlying connectivity (e.g. IPsec, segmentation, routing behavior).
  • Understanding of enterprise authentication flows (e.g. 802.1X/RADIUS).
  • Solid experience troubleshooting in enterprise‑scale network environments.
  • Experience working within ITIL-based operations (incident/change management).
  • Ability to work independently and take ownership of operational work.
  • Strong communication skills in operational and stakeholder‑facing situations.
  • Python scripting: reading, modifying, and writing simple scripts.
  • Experience with REST APIs and Git.
  • Experience with monitoring/alerting and understanding service impact.

Preferred skills

  • Experience with Aruba Central, Aruba SD‑Branch, and/or Aruba ClearPass (or comparable enterprise networking / SD‑WAN / NAC platforms).
  • Ability to read logs and troubleshoot authentication/NAC-related issues.
  • Confidence to make configuration or policy changes in network and NAC environments.
  • Automation mindset: improving operational efficiency using scripting, APIs, or similar.
  • Familiarity with DevOps practices (e.g. version control, CI/CD concepts).

Candidate profile

  • Service-oriented, proactive, team-first engineer who takes ownership and delivers results.
  • Comfortable operating in a high-impact environment and handling incident pressure.
  • Ability to contribute to improving both the service and team ways of working.
  • Senior-level qualities: decision-making, mentorship, and leadership within the squad.
  • Demonstrable impact such as improving stability, reducing incidents, or increasing operational efficiency.
  • Language: English mandatory.

Eisen

  • DevOps
  • Git
  • REST APIs
  • SD-WAN
