Job summary

LayerZero Power Systems LLC. is seeking a senior IC-DC power systems engineer to design, validate, and optimize high-density DC power distribution for AI-focused data centers.

You will own architecture-to-test processes for DC blocks, switchgear, and rack interfaces, collaborating with R&D leadership. Responsibilities include detailed 800 VDC/DC concepts, lab validation, and integration with DCIM/SCADA systems.

Qualifications

• Bachelors 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 or equal.
• Lab-forward: prototype build-up, power-analyzer and scope work, and test-plan authorship.

Responsibilities

• Design 800 VDC central power blocks and DC distribution, scalable toward 1500 VDC.
• Simulate AC/DC and DC/DC stages using SiC and GaN devices.
• Develop DC switchgear, solid-state and hybrid breakers, fusing, and coordination schemes.
• Perform DC fault-current, short-circuit, arc-flash, and insulation-coordination analysis.
• Engineer downstream distribution — DC busway, PDU, rack interfaces.
• Build, instrument, and test prototypes in the R&D lab — thermal, load, transient testing.
• Integrate metering, controls, and telemetry with DCIM/SCADA; support ESS/BBU ride-through integration.
• Produce schematics, BOMs, test plans, and documentation; support certification and manufacturing hand-off.
• Design to OCP, NEMA, IEEE, IEC 62443, UL 1778/2367 and NEC requirements; collaborate with partners.
