About this role

Lead the design and operational integration of large-scale fluid systems for Fuse's Z-Star pulsed-power accelerator, managing millions of liters of transformer oil and deionized water through CFD simulation, thermal analysis, and commissioning support.

What you'll do

  • Design large-scale fluid circuits for storage, recirculation, and reconditioning of transformer oil and DI water systems
  • Build and run CFD models to optimize flow paths and identify risks like cavitation or turbulence
  • Develop fluid-quality protocols including breakdown-voltage testing, moisture control, and particle filtration
  • Perform thermohydraulic analyses and design cooling strategies for heat loads from pulsed discharges
  • Create P&IDs, system schematics, and operational procedures for all fluid subsystems
  • Support on-site fabrication, testing, commissioning, and troubleshooting of fluid systems

What they're looking for

  • CFD tools (ANSYS Fluent, CFX, OpenFOAM, or COMSOL)
  • Large-scale industrial fluid system design and pump/filter/heat exchanger selection
  • Transformer oil and dielectric fluid properties and testing
  • Convective and forced-flow heat transfer analysis
  • Piping and instrumentation diagram development
  • Deionized water systems and ion-exchange resin bed operation
  • Python for data post-processing and automation
  • ASME piping codes and high-voltage facility standards
