Job summary

LayerZero Power Systems, Inc. seeks a senior individual-contributor engineer to design, build, and validate DC power-distribution hardware for AI and high-density data centers.

You will own detailed design of 800 VDC blocks, 1500 VDC scalability, and lab validation, reporting to the Director – High Power Solutions – R&D. You will develop conversion stages using SiC/GaN, design switchgear, perform fault and insulation analyses, and prepare schematics, BOMs, and test plans for UL/CSA/ETL

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; CFD thermal modeling.

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.).
