Job summary

LayerZero Power Systems LLC is seeking a senior design engineer to craft and validate DC power-distribution hardware for AI and high-density data centers. You will lead detailed design, lab validation, and certification activities, reporting to the Director – High Power Solutions — R&D.

You will own 800 VDC central power blocks, DC switchgear, protection schemes, and downstream distribution, collaborating with ORNL and industry partners to ensure manufacturability and reliability.

Qualifications

• Bachelor's in electrical engineering with power-electronics emphasis (MS preferred).
• 8+ years designing DC or power-electronics systems for critical infrastructure.
• Depth in LVDC/HVDC distribution, converter topologies, and DC protection and coordination.
• Hands-on SiC and GaN converter design, magnetics, and thermal management.
• Simulation fluency — PLECS, Simulink/MATLAB, SPICE, and CFD thermal modeling or equal.
• Lab-forward: prototype build-up, power-analyzer and scope work, and test-plan authorship.

Responsibilities

• Execute detailed design of 800 VDC (±400 VDC) central power blocks and DC distribution, scalable toward 1500 VDC.
• Design and simulate AC/DC and DC/DC conversion stages using SiC and GaN devices for high density and efficiency.
• Develop DC switchgear, solid-state and hybrid breakers, fusing, and selective-coordination schemes.
• Perform DC fault-current, short-circuit, arc-flash, and insulation-coordination analysis.
• Engineer downstream distribution — DC busway, PDU, RPP/RDP panelboards, and HVDC connectors to the rack DC-DC power shelf.
• Build, instrument, and test prototypes in the R&D lab — thermal, load, transient, and life-cycle testing.
• Integrate metering, controls, and telemetry with DCIM/SCADA; support ESS/BBU ride-through integration.
• Produce schematics, BOMs, test plans, and documentation; support UL/CSA/ETL certification, DVT, and manufacturing hand-off.
• Design to OCP, NEMA, IEEE, IEC 62443, UL 1778/2367 and NEC requirements; contribute to development partnerships (ORNL, etc.).
