About the role

Lead the design and safety engineering of medium-voltage DC distribution systems for gigawatt-scale AI campuses, from architecture through safety case, coordinating with SST and facility electrical teams and driving vendor strategy for DC components.

Responsibilities

  • Architect MVDC distribution for gigawatt-scale campuses: pick the voltage level, topology, and grounding scheme, and defend every choice on fault behavior, stability, and cost.
  • Own the system EMT model and run the fault and stability analysis program that proves a fully converter-interfaced network holds, with margins you can state and stand behind.
  • Set the protection philosophy with the protection engineer and own the safety case where standards haven't caught up, rigorous enough to survive review by an AHJ working from an incomplete code.
  • Lead the DC Systems team, define its first deliverables, and hold the technical interfaces to the SST and facility electrical teams so nothing falls between them.
  • Drive vendor strategy for SSCBs, converters, and DC-rated components, and know which gaps in the ecosystem the architecture must design around.

Qualifications

  • 12+ years in power systems or power electronics, with direct MVDC or HVDC system design experience: shipboard MVDC, HVDC converter stations, or grid-scale converter-dominated networks, designed end to end.
  • You own the system-level story: architecture, grounding, fault behavior, and stability of converter-dominated networks, and you can walk a DC fault sequence from initiation to clearing.
  • You're fluent in EMT simulation (PSCAD/EMTDC) and have used it to prove designs, not just to check them after the fact.
  • You've built defensible safety cases ahead of immature standards, in the territory between IEEE 1709 and the MVDC provisions just arriving in NEC 2026.
  • You've led small technical teams and know what their first deliverable should be.
  • You know what evidence would make you kill a concept, and you'd say so before anyone spends another dollar on it.
  • Bonus: SSCB and DC breaker ecosystem knowledge, depth in DC grounding and insulation coordination, islanded or behind-the-meter system experience, or standards committee participation.
