About the role
The Product Engineering, DC Systems Team designs the medium-voltage DC distribution systems that will power gigawatt-scale AI campuses. This role involves architecting MVDC distribution for such campuses, ensuring the system's architecture, grounding, fault behavior, and stability are all defensible. The candidate will also lead the DC Systems team, define its first deliverables, and ensure technical interfaces with the SST and facility electrical teams are clear.
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.
- Build 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.
Requirements
- 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
- Standards committee participation
