Structural Engineer, R&D for Large-Scale AI Compute

Fluidstack; Los Angeles (CA); On-site; USD 210,000 - 260,000; Full time

Job summary

Fluidstack in Los Angeles, CA seeks a structural engineer focused on high‑speed machinery to ensure safe, reliable containment and load paths for massive compute infrastructure. You will perform structural analyses on rotating components, coordinate with turbomachinery engineers on rotordynamic and modal studies, and design test cells and containment structures for extreme operating conditions.

The role emphasizes hands‑on ownership of designs from calculation to finished hardware, with a strong

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 rather than trusting the model.
• You’ve owned a containment or burst case and made the argument for why it holds to people whose safety depended on it.
• You’ve worked the modal and critical-speed problem jointly with whoever designed the aerodynamics, early enough to change both.
• You’ve signed off a structure that got built, and you were there when it was first loaded.

Responsibilities

• Own the structural analysis of the machine: impeller and rotor stress, casing and pressure containment, and the load paths through the packaged unit.
• Design the pressure-containing structures, and carry them from first calculation to hardware people are willing to stand next to.
• Run the rotordynamic and modal work alongside the turbomachinery engineer, covering critical speeds, whirl and the magnetic bearing interface.
• Design the containment case, so an energetic failure at speed stays inside the machine.
• Design the test cell structures and fixturing that carry the article, the drive and the loop under load.
