Senior Network Operations Engineer - Enterprise Infrastructure
Cyber Instincts ABBeskrivning
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.
