Job summary

Fluidstack in Austin is seeking a senior mechanical engineer to own the structural analysis of large-scale machines and containment systems for high-power thermofluid projects. You will design pressure vessels, perform rotordynamic analyses, and coordinate with turbomachinery and test teams to ensure safe, reliable operation at grid-scale compute speeds.

The role emphasizes early involvement with aerodynamic integration, real-world validation against test data, and collaboration with a

Qualifications

You’ve taken a pressure-containing design from calculation through to a fabricated article, and it held.
You’ve run FEA on rotating hardware and correlated it against test data.
You’ve owned a containment or burst case and made the argument for safety.
You’ve worked the modal and critical-speed problem jointly with aerodynamics early enough to influence both.
You’ve signed off a structure that got built and was loaded.

Responsibilities

Own the structural analysis of the machine: impeller and rotor stress, casing and containment.
Design the pressure-containing structures and drive them from calculation to production.
Run rotordynamic and modal work with the turbomachinery engineer for critical speeds.
Design the containment case to keep energy contained at speed.
Design test cell structures and fixturing to carry the article under load.
