Data Center Structural Engineer

Location: Austin, TX, NYC, San Francisco, CA, Phoenix, AZ, or Seattle, WA preferred. Strong remote candidates will be considered. 25% travel required for all locations.

About the Role

Engineer the mechanical systems of the modular product: cooling, piping, and airflow from concept to released drawings. Own the liquid cooling loops, pumps, and heat rejection design the modular product's density depends on. Solve the integration problems where mechanical meets structure and electrical: routing, interfaces, and tolerances where the disciplines collide. Support the factory and field: mechanical RFIs answered same-day, fixes engineered into the next revision. Prototype and validate: mockups, fit checks, and first-article reviews you attend in person.

Responsibilities

• Design mechanical systems for modular infrastructure, focusing on cooling, piping, and airflow.
• Develop and own liquid cooling loops, pumps, and heat rejection systems.
• Resolve integration challenges between mechanical, structural, and electrical systems.
• Support prototype builds, first-article reviews, factory acceptance testing, and production launches.
• Collaborate directly with fabrication shops, manufacturers, and installers to resolve design issues.
• Create P&IDs, equipment layouts, piping drawings, and fabrication-ready mechanical packages.
• Iterate designs rapidly while maintaining configuration control.

Requirements

• 7+ years designing mechanical systems for modular infrastructure, cooling systems, industrial equipment, or manufactured products.
• Experience designing liquid cooling systems, pumps, heat exchangers, piping systems, cooling towers, or heat rejection systems.
• Experience developing P&IDs, equipment layouts, piping drawings, and fabrication-ready mechanical packages.
• Experience supporting prototype builds, first-article reviews, factory acceptance testing, or production launches.
• Experience working directly with fabrication shops, manufacturers, installers, or production teams to resolve design issues.
• Proficiency with SolidWorks, Inventor, Revit, Creo, or similar 3D mechanical design tools.

Preferred Qualifications

• Direct-to-chip cooling, liquid cooling loops, CDUs, or AI/HPC cooling experience.
• Modular data centers, equipment skids, or prefabricated infrastructure experience.
• Advanced proficiency with SolidWorks, Inventor, Creo, or similar mechanical product design tools.
• DFM/DFA and manufacturing-focused design experience.
• First-article builds, FAT, production launches, or manufacturing engineering experience.

About the Team

Examples of key problems the team is working on:

• Design the module that makes 6-month data centers possible. Fluidstack builds data centers in months, not years, and that speed lives in the modular product: a data center engineered as a manufactured unit, not a construction project.
• Take designs from concept to the manufacturing line in weeks. Concept, released drawings, first article, and rate production on a compressed schedule, with the factory building from your work the same month you release it.
• Engineer for the thousandth unit, not the first. On the way to 10 GW, every drawing, tolerance, and BOM decision has to survive rate manufacturing, so repeatability is designed in from the start.

Skills

• Hands-on experience engineering mechanical systems for complex physical products or modular construction.
• Strong drawing skills with minimal fabricator feedback; ability to resolve issues quickly.
• Cross-disciplinary collaboration; avoids siloed problem-solving.
• Experience supporting production launches of your own designs.
• Fast iteration with strong configuration control.
• Bonus: Liquid cooling depth, sheet metal and piping design, 3D CAD mastery (SolidWorks, Inventor, Revit), DFM instincts.
