Principal Thermofluids Engineer

Lead/Sr Thermofluids Engineer - El Segundo, CA - Industrial Power/Heat Exchangers

I’m supporting an early-stage startup in El Segundo, CA area that is building a next-generation industrial power conversion system, and I’m looking for a Lead/Senior Thermofluids Engineer who wants true ownership of core hardware.

This person will own the thermal-fluid design of critical heat-exchange hardware and architecture that directly drives system performance, efficiency, and test success.

The work will involve:

• Thermal-hydraulic design and sizing of compact, high-performance heat exchangers
• Pressure drop, heat transfer, and flow distribution analysis
• 1D modeling alongside 3D CFD
• Taking designs from early architecture through fabrication, inspection, build, and test
• Working directly with founders and cross-functional leads
• Coordinating closely with external vendors / fabricators on advanced heat-exchange hardware

Ideal background would include experience with some combination of:

• Compact heat exchangers, plate-fin, or similar architectures
• High-pressure / high-temperature thermal-fluid systems
• Combustion-side heat transfer or pressure-containing thermal hardware
• Thermal stress, pressure-boundary considerations, ASME-related design practices

This is a good fit for someone who wants to move fast , own meaningful hardware, and be early enough in a company to actually shape the product rather than inherit it.

If this sounds like you, or someone in your network, send me a message or email me directly at [email protected] and I'll be in touch promptly.
