Senior Network Operations Engineer – Enterprise Infrastructure

Lund, Sweden | On-site | Long-term assignment (Oct 2026 – Sep 2027, strong extension potential)

About the role

We're looking for an experienced network operations specialist to join a large-scale Infrastructure Services team for one of our clients - a global industrial technology company based in Lund. This is a hands-on, operationally critical role: you'll be the person keeping a sprawling enterprise network environment stable, secure, and running, across Cisco and HPE Aruba infrastructure.

You'll work close to the metal - configuring, monitoring, troubleshooting - while also coordinating with internal IT teams and external telecom providers to keep everything within SLA. If you like solving real problems in a live, 24x7-critical environment rather than just writing documentation about them, this is built for you.

What you'll actually be doing

Day-to-day administration of enterprise-scale Cisco and HPE Aruba networks

Configuring and maintaining HPE Aruba environments, including SD-WAN

Managing Cisco Nexus infrastructure

Keeping switches, routers, and wireless infrastructure (controllers + APs) healthy and fast

Working inside Cisco ISE, Prime, and DNAC for network management and security

Driving incidents to resolution within SLA, using ServiceNow and ITIL-based processes (Incident, Problem, Change, Knowledge Management)

Liaising directly with telecom providers on WAN/connectivity issues

Contributing to proactive failure detection and planned maintenance, not just firefighting
