Electrical Engineer: Power Systems

Position Summary

Voya Energy is seeking a Senior Power Systems Engineer to design, build, and test the power system architecture for our metal-fueled generator technology.

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 "charge-and-switch" 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 "available now" over "perfect in six months."
• 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

• 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.
• 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.
