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.
