Plumbing Engineer, R&D
Austin, TX$169k - $208kFull-timePosted today
About the role
Role focused on owning and integrating plumbing design for data center cooling infrastructure within Fluidstack's infrastructure R&D group, delivering repeatable, kit-able water and drainage systems for gigawatt-scale AI data centers.
Responsibilities
- Own the plumbing design. Design domestic water, process and make-up water, condenser water piping, drainage, and stormwater systems for data center buildings and prefabricated modules, from concept through construction documents.
- Size and specify. Run hydraulic calculations, select pumps, valves, backflow preventers, water heaters, and storage, and write the specifications vendors and contractors build to.
- Hold the codes. Keep designs compliant with plumbing, mechanical, and health codes across jurisdictions Fluidstack builds in, and manage the permit and inspection questions that come back.
- Integrate with cooling. Work with the mechanical, water-quality, and controls engineers so make-up water, treatment, and blowdown are designed as one system with the cooling plant.
- Support the build. Review contractor submittals and shop drawings, answer RFIs, and walk installations through commissioning.
Qualifications
- 5+ years of plumbing or piping design engineering on industrial, mission-critical, or large commercial facilities, with at least one project taken through construction documents and commissioning.
- Working knowledge of the IPC or UPC, IMC, and local amendments, and of how to get a design through permit review.
- Hands-on with hydraulic calculations, pump and pipe sizing, backflow protection, and water storage design.
- Fluency in Revit or AutoCAD MEP and a hydraulic modeling tool.
- Experience reviewing contractor submittals and answering RFIs, and knowledge of deviations that matter.
- Ability to write specifications a contractor can bid without a meeting.
- Bonus: Professional Engineer license or CPD certification. Data center or liquid-cooling plant experience. Water treatment or industrial process piping background.
