Job summary

LayerZero Power Systems LLC in Aurora, OH is seeking 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 for 800 VDC blocks and rack power interfaces, and work toward scalable toward 1500 VDC.

You will perform lab validation, develop protection schemes, integrate metering and telemetry, and prepare schematics, BOMs, and test plans for UL/CSA/ETL certification.

Qualifications

• Bachelor's in electrical engineering, 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/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 central blocks and DC distribution, scalable toward 1500 VDC.
• Design and simulate AC/DC and DC/DC conversion stages using SiC and GaN devices.
• 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.).
