Thermofluids Controls Engineer: High-Scale Cooling

Fluidstack; Austin (TX); On-site; USD 140,000 - 190,000; Full time

Job summary

Fluidstack seeks a control systems engineer to own the machine control architecture and test rigs. You will write safety interlocks, fault handling, and capacity control strategies, delivering robust hardware-in-the-loop validated software for production deployment.

The role requires deep experience with high‑scale chillers, compressors, and turbine loops, and collaboration with site teams. As part of the Thermofluids R&D team, you’ll influence machine performance at grid scale, ensuring safety

Qualifications

• Wrote control logic for rotating machinery and was present at first run.
• Designed interlocks for fault scenarios to protect hardware and personnel.
• Conducted hardware-in-the-loop testing to catch issues before commissioning.
• Tuned control loops on live machines and analyzed model-vs-plant discrepancies.
• Delivered well-documented control systems ready for handing over to operators.

Responsibilities

• Own the control architecture for the machine and the test rigs.
• Write safety interlocks and fault-handling logic for critical systems.
• Deliver capacity control via motor and turbine speed, avoiding valve throttling.
• Validate the control system with hardware-in-the-loop before live testing.
• Coordinate deployment from test cell to production chiller and site integration.
