Commissioning Lead

What you’ll do

A data center isn't done when the last wall goes up — it's done when every system is proven to work, under load, exactly as designed. As a Commissioning Lead at Giga, you own that final mile. You'll lead end-to-end commissioning on mission-critical facilities from first energization through full system validation and owner handoff, working across MEP, electrical, and controls systems in some of the most complex buildings being constructed today. This is the role where the entire project comes together — or falls apart. You'll be the person in the field making sure it's the former: coordinating vendors, driving the Cx schedule, and signing off on systems that the world's most demanding AI workloads will depend on. If you want to be the last line between a construction project and a live data center, this is your seat.

Where you’ll work

This is an on-site position that requires long term travel and/ or short term relocation. This person should be comfortable with 3-6 month periods of being at a location before moving to the next.
