About the role

Lead electrical design and sizing of multi-hundred-megawatt storage plants, qualify and dual-source BESS vendors, define plant dispatch with solar and on-site generation, drive NFPA 855 compliance and commissioning for grid-scale battery energy storage systems (BESS) integrated with Fluidstack's AI infrastructure.

Responsibilities

  • Own the storage plant design. Lead the electrical design and sizing of multi-hundred-megawatt storage plants, from single line, protection and grounding through power and energy ratings and augmentation strategy, across several concurrent gigawatt sites.
  • Qualify and dual-source BESS vendors. Choose on technical merit, and run factory witness testing, failure mode review and warranty terms alongside supply chain.
  • Define how the plant dispatches. Specify how storage, solar and on-site generation dispatch together so the plant holds a firm load profile through resource swings and generator trips.
  • Get fire safety approved before equipment lands. Drive NFPA 855 compliance, hazard mitigation analysis and large-scale fire test evidence through the AHJ and the insurer before equipment reaches site.
  • Take each plant through commissioning. Complete capacity and round-trip performance testing and controls integration before the first training load connects.

Qualifications

  • 10+ years of experience in grid-scale battery energy storage engineering, from plant design and sizing through vendor qualification, fire safety approval, and commissioning.
  • You've taken grid-scale battery storage from single line to energized plant, and you can name the sites and the megawatts.
  • You've sized a storage system against a real duty cycle and lived with the result, including augmentation calls and identifying model inaccuracies.
  • You've chosen between BESS vendors on technical grounds, participated in factory witness testing, and scrutinized datasheets.
  • You've argued NFPA 855 and hazard mitigation analysis in front of an AHJ or insurer and obtained approval.
  • You've integrated storage controls with generation and load so the combined plant behaves as one machine.
  • You write clearly enough that procurement leads, fire marshals, and CEOs can extract needed decisions from the same document.
  • You're comfortable with regular travel: expect 25% or more.
  • Most of our team is based in Austin, TX; strong preference for Austin with hybrid model, but locations may be considered for the right candidate.
