Senior Thermofluids Engineer - Data Center Heat Systems

Fluidstack; Austin (TX); Hybrid; USD 150.000 - 210.000; Vollzeit

Zusammenfassung

Fluidstack is hiring a senior thermofluids engineer to define the machine cycle and fluids, focusing on high‑pressure fluid systems and heat exchanger design. You will work on machine architectures at scale for data-center compute, with regular travel and a strong preference for Austin, TX.

You will model thermodynamic cycles, size exchangers, and validate predictions against test data, communicating findings to cross‑functional teams in a clear way.

Qualifikationen

• 10+ years of experience in thermofluids engineering and cycle modeling.
• Able to defend model assumptions to challenge and stakeholders.
• Sizable heat exchangers using published correlations and data.
• Calibrated models against machine data and reported gaps honestly.
• Written analyses readable by engineers and non-engineers alike.

Aufgaben

• Define machine requirements and the cycle model that sets fluids, pressures and flows.
• Design large-area heat exchangers, influencing the data center footprint.
• Architect the fluid system piping, valves, reliefs, and headers.
• Run trades: pressure drop, temperature rise, and subcooling in models.
• Compare predictions to test data and clearly report discrepancies.
