Fluids / Mechanical Engineer, R&D
Core
Designing and building gigawatt-scale thermofluid systems (compressors, chillers, heat exchangers) for AI data centers to reject massive heat loads.
Role type
Senior IC mechanical/thermofluids engineer (R&D)
Builds
Custom machine architectures, heat exchangers, and fluid systems for data center cooling
Domain
Data center infrastructure / Thermofluids / High-power cooling
Deliverable
production ML models | product features | dashboards & analysis | research | client delivery | infrastructure | physical/clinical work
Required skills
thermodynamic cycle modeling, heat exchanger sizing, fluid system design, two-phase heat transfer analysis, real-gas properties, relief path design, test stand data reconciliation
Preferred skills
vapor-compression and transcritical cycles, propulsion and cryogenic fluid systems, high-pressure piping design, data center thermal architecture (CDUs, dry coolers)
Technologies
CoolProp, REFPROP, Cavallini, Gnielinski, Wang
Responsibilities
Define machine cycle models (working fluid, pressures, temperatures, flows); design heat exchangers with massive surface areas; design fluid systems (piping, valves, headers); run design trade-offs (air-side temp rise, face velocity, subcooling); validate models against test stand data; sign off on relief path safety
Seniority
Senior, hands-on IC
