Job summary

Voya Energy in Hayward, CA is seeking a Senior Power Systems Engineer to own the design, build and test of the power system architecture for our metal-fueled generator technology. You will orchestrate the interface between generator, battery storage, local load, and grid, emphasizing fast prototyping and robust hardware.

The role requires deep hands-on experience in hybrid inverters, high-power electronics, thermal management and end-to-end development, from trade studies to production, within a

Qualifications

• Bachelor’s degree or higher in Electrical Engineering or related field.
• 7+ years of relevant industry experience in system-level power electronics.
• Direct experience with High Power (25-250kW) Hybrid Inverters and DC-DC conversion.
• Familiarity with AC switching/transfer logic and protection coordination.
• Ability to perform "worst-case" analysis and simulations (SPICE/PLECS) to ensure design robustness.
• Proficiency in PCB layout with a focus on DFM (Design for Manufacturing).
• Proficiency in Altium Designer (or similar) with specific experience in high-current/high-voltage layout.
• Proficiency in 3D CAD software (e.g., SolidWorks, NX, or Creo). Demonstrated experience working in PDM and/or PLM environments.
• Expert-level use of PLECS, PSIM, or MATLAB/Simulink to simulate power stages and control loops before building hardware.
• Demonstrated knowledge of UL 1741 and IEEE 1547.
• Hands‑on experience with heat sink sizing, fan selection, and thermal interface materials to keep the system stable under load and operating environment requirements.
• Demonstrated firmware experience, specifically C/C++ for microcontrollers to ensure the hardware and software are aligned.
• Experience with development testing, failure analysis, and debugging complex systems. The successful candidate will own and drive documentation and configuration management.
• Comfortable working in an environment based on accountability: scope, schedule, budget, 2-way feedback and collaboration.

Responsibilities

• Design, build, and test the power system architecture for metal-fueled generator tech.
• Develop hybrid inverter, converter, switches, and BMS architectures for rapid prototyping.
• Design switching logic to power onsite load from hybrid system or grid.
• Model energy flow and transitions between generator, battery, and grid.
• Source components across vendors to shorten lead times.
• Collaborate with mechanical, controls, and data teams; support testing and validation.
• Create electrical schematics and ensure adherence to safety standards.
• Document procedures for new equipment and systems.
