Position SummaryVoya Energy is seeking a highly skilled and motivated Senior Electrical Engineer to take ownership of the design, build, and test of the power system architecture essential to the development and scaling of our metal-fueled generator technology. You will be responsible for the architecture that manages power flow between the generator, the battery storage, the local load, and the utility grid-including a switching solution that allows the grid to take over the load seamlessly when desired. The ideal candidate has a hands-on approach based on engineering first principles and industry experience, a deep understanding of hybrid inverters and converters, and demonstrated experience in bringing hardware (components, sub-assemblies, top-level assemblies) through a complete workflow: conceptual trades/design, performance prediction/analysis, development testing iteration and eventually to production. Collaboration with mechanical, fluids, automation, data and controls is essential.
Responsibilities:- Rapid Development: Design and bring up the Hybrid Inverter, converter, switches and battery management system architectures with a focus on speed-to-prototype.
- Load & Grid Management: Design the switching logic and hardware to allow the onsite AC load to be powered by either the hybrid system or the grid.
- Intelligent Power Flow: Build the 2charge-and-switch2 logic, ensuring the system can buffer energy from the generator and manage the transition between battery, generator, and grid power.
- Practical Architecture: Source components from multiple vendors to avoid long lead times. You prefer 2available now2 over 2perfect in six months.2
- Hardware-Mechanical Synergy: Use your mechanical aptitude to ensure electronics fit physical constraints, accounting for thermal management and ruggedized packaging.
- Small Team Collaboration: Thrive in a tight-knit environment where you help define requirements for software and mechanical peers to move the whole project forward. Directly support design, test readiness and test data reviews.
- Testing & Validation: Develop test plans and perform development testing for verification and validation of assemblies.
- Create and maintain system electrical schematics.
- Adhere to relevant safety standards.
- Document assembly and operating procedures for new equipment and systems.
Qualifications:- Bachelor9s 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 2worst-case2 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.
- Familiar with modern engineering collaboration toolsets: Confluence,, Slack, Asana, etc.
- Demonstrated experience reading electrical schematics/drawings.
- Demonstrated ability to operate in a fast-paced, start-up environment. Hands-on and biased towards action.
Location: Hayward, CA. Full-time on-site.
Salary & Benefits:- Competitive salary and equity compensation commensurate with experience
- Unlimited PTO
- Medical, dental, and vision coverage
- 401(k) plan
