Job summary

LayerZero Power Systems LLC is seeking a senior electrical engineer to design, build, and validate DC power-distribution hardware for AI and high-density data centers. You will report to the Director - High Power Solutions - R&D and own DC power blocks, switchgear, bus distribution, and rack interfaces.

You will design 800 VDC to 1500 VDC architectures, simulate AC/DC and DC/DC stages using SiC/GaN devices, develop DC switchgear and protection, and test prototypes in the R&D lab to ensure

Qualifications

• Bachelor's degree in electrical engineering with power-electronics emphasis
• 8+ years designing DC or power-electronics systems for critical infrastructure
• Experience with LVDC/HVDC distribution, converter topologies, and DC protection and coordination
• Hands-on SiC/GaN converter design, magnetics, and thermal management
• Simulation fluency - PLECS, Simulink/MATLAB, SPICE, 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.)
