Senior Solid State Equipment Engineer
About The Position
LayerZero Power Systems LLC. is a global provider of power-distribution solutions for critical industries, with a primary focus on data centers. This senior individual-contributor engineering role designs, builds, and validates direct-current power-distribution hardware for AI and high-density data centers. The position reports to the Director – High Power Solutions — R&D. The engineer owns detailed design and laboratory validation of DC power blocks, DC switchgear and protection, bus distribution, and the rack power-shelf interface, translating architecture direction into tested, manufacturable hardware. The work includes high-voltage DC distribution and conversion, protection and coordination, downstream distribution equipment, prototype testing, telemetry integration, certification support, and manufacturing hand-off.
Requirements
- Bachelor's degree in electrical engineering with a power-electronics emphasis.
- At least 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 experience.
- Fluency with PLECS, Simulink/MATLAB, SPICE, and CFD thermal modeling or equivalent.
- Hands-on laboratory experience with prototype build-up, power-analyzer and oscilloscope work, and test-plan authorship.
Nice To Haves
- Master's degree.
- Data center power experience with PDU, STS, RPP, or busway at 30 kW–1 MW racks.
- UL/CSA/ETL certification testing and familiarity with IEC 62443 security.
- ESS/BBU integration, DCIM/SCADA telemetry, and firmware/controls collaboration.
- Experience delivering skids, eHouses, or other prefabricated power modules.
- Experience with solid-state power converters and systems, including solid-state transformers, solid-state and hybrid DC breakers, and rectifier/inverter power blocks, including their controls, switching, and gate-drive design.
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 silicon carbide (SiC) and gallium nitride (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, including 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, including 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, including ORNL.
Benefits
- $0-cost dental insurance.
- $0-cost vision insurance.
- $0-cost short-term and long-term disability insurance.
- $0-cost life insurance with additional buy-up options.
- Medical plan choices, including one no-cost medical option and two additional buy-up plan options.
- $0-cost Employee Assistance Program offering confidential counseling and support services.
- Employer Health Savings Account contributions.
- Retirement plan options with generous employer matching contribution.
