What You’ll Do

Before a data center can go live, every test result, every deficiency, and every sign-off has to be tracked, documented, and accounted for — and that record has to be airtight. As a Cx Assistant at Giga, you're the person making sure nothing falls through the cracks. You'll support the Commissioning Manager and Site Leads with documentation, scheduling, and test coordination, learning the commissioning process from the ground up on some of the most complex buildings being constructed today. This is a great entry point into commissioning for someone detail-obsessed who wants to build toward a Site Lead or Cx Lead career path.

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.

• Maintain and organize the commissioning record package, including test results, deficiency logs, submittals, and as-built documentation
• Track deficiencies identified during testing through to closure, following up with vendors and trades on outstanding items
• Assist in preparing commissioning plans, FPT scripts, and IST procedures for review by the Commissioning Manager
• Help coordinate subcontractor and vendor schedules for systems startup and functional testing activities
• Attend and take notes during pre-functional inspections, functional tests, and integrated systems tests, flagging observations to the Site Lead or Commissioning Manager
• Support punch list tracking and help compile documentation for owner turnover and final acceptance
• Assist with RFI and submittal tracking related to commissioning scope

Requirements

• 0-2 years of experience in commissioning, construction, or a related technical field; internship or field experience on mission-critical or industrial construction projects a plus
• Familiarity with MEP and electrical systems (generators, UPS, switchgear, cooling infrastructure, BMS/controls) through coursework, internships, or early field experience
• Strong organizational skills and comfort managing detailed documentation across multiple active workstreams
• Ability to read basic construction drawings and specifications, with willingness to build deeper technical fluency on the job
• Comfortable working in an active, fast-moving construction environment alongside multiple trades and vendors

Bonus points
