Job Description

The role

We are building our L3 Support Line from scratch to serve as the datacenter center of expertise for servers, firmware (BIOS/BMC), and deep Linux diagnostics across Europe and the US.

This is a senior technical role focused on deep investigations, cross-site pattern detection, and driving permanent fixes with R&D and ODM vendors. You will turn complex incidents into scalable solutions and elevate L1/L2 capabilities through strong technical enablement.

Location: Mäntsälä, Finland (you’re welcome to work in our DC in Mäntsälä, Finland).

Your responsibilities will include:

Deep Technical Investigation (Primary Focus)

  • Lead root cause analysis beyond L2 depth (GPU failures, firmware issues, Linux-level faults, HW/SW interactions).
  • Detect recurring patterns across sites and convert findings into durable fixes.
  • Own technical workstreams during high-severity incidents.
