What you'll do

As Plumbing and Fire Protection Designer at Giga, you will produce the plumbing and fire protection designs for our AI data center infrastructure projects. You'll design restroom plumbing and roof drainage, lay out sprinkler systems and run the hydraulic calculations, prepare riser diagrams, and review and edit specifications. You'll collaborate with clients, architects, structural and mechanical engineers, electrical teams, code officials, and AHJs to deliver designs that meet stringent reliability, operational, and code requirements. Our Engineer of Record sets design direction and seals the drawings. This is a high-visibility, hands-on role for someone who takes pride in clean, correct drawings, works well with a team, and thrives in fast-paced, complex technical environments.

Where you'll work

This role is based in one of our offices (Houston, TX / Long Beach, CA / San Francisco, CA / Reno, NV) or Fully Remote. We work in person because the best engineering happens when smart people are in the same room. Some travel to active project sites and client meetings should be expected.

That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs. If you're the right person for this role, we'll have a conversation about what works.
