Senior Electrical Engineer: Renewable Energy Power Systems

Voya Energy is commercializing a groundbreaking metal-based fuel to rapidly deploy reliable, clean, affordable electricity anywhere on Earth.

Our breakthrough technology allows us to convert abundant, high-energy, recycled metals into a powerful, safe, durable fuel. We are also creating a foundational new category of energy generation devices, delivering fast access to power - free from the limitations of the grid.

We are assembling a highly-experienced team of visionary founders, tenacious researchers, multi-disciplinary first principles engineers, battle-tested operators and world-class investors to deliver on Voya’s ambitious mission.

Join us in fueling our electric future.

Voya 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.

• 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.

• 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., Solid Works, 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.
