Overview The Commissioning Engineer (Mechanical) in the PS department will perform L2 installation verification and L3 equipment start-up and functional testing at the Stargate Norway hyperscale data centre near Narvik. The role focuses on mechanical and cooling systems, including closed-loop liquid cooling for high-density GPU halls, and requires complete, accurate documentation for progression to the next commissioning level. The assignment is expected to run through 31 December 2026, with possible extension.

Responsibilities

• Verify mechanical equipment and piping installation against design documents, P&IDs and isometrics; record deviations and redlines.
• Inspect equipment alignment, supports, vibration isolation, access, labelling, valves, instruments, strainers and flow direction.
• Witness pressure and leak testing; review certificates and oversee or witness flushing, cleaning, sampling and coolant filling.
• Complete and sign L2 checklists, maintain inspection records and raise and track punch items in the commissioning system.
• Prepare and conduct L3 start-up activities under site permit-to-work and lockout/tagout procedures.

• Coordinate BMS point-to-point and loop checks, support test and balance, and complete L3 test scripts and handover documentation.

Required Education Mechanical engineering or technician education, marine engineering training, or equivalent practical qualification as a skilled pipefitter or HVAC technician. Relevant hands-on commissioning experience may support an equivalent background.

Required Experience At least five years of mechanical or HVAC commissioning experience, including data centre commissioning.
