Mechanical Cell Engineer

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.

Position Summary:

We’re looking for scientists and engineers who are passionate about research, innovation, and entrepreneurship to help develop and scale the cell architecture for Voya’s proprietary metal-air fuel cell. The successful candidate will take a leading role in setting the technical direction of the company.

Responsibilities:

• Design, build, and validate a high-power metal-air fuel cell for Voya’s generator.
• Work with material scientists to select and optimize cathode, anode, membrane/separator, and electrolyte materials as well as form-factor.
• Develop and iterate novel current collector, separator/membrane, and electrode architectures to improve cell power, efficiency, and durability.
• Develop manufacturing procedures for novel architectures.
• Work with subscale and stack teams to identify scaleup limitations and implement innovative solutions.
• Work with subscale and stack teams to develop operational strategies that improve cell power, efficiency, and durability.
• Rapidly prototype bench-scale electrochemical flow cells to test new chemistries, architectures, materials, and stack configurations before committing to pilot-scale builds.
• Design and iterate cell & stack hardware, including bipolar plates, flow fields, manifolds, end plates, gaskets, and compression/clamping systems to improve cell power, efficiency, and durability.
• Own mechanical design and tolerancing of cell and stack components in CAD (SolidWorks or equivalent).
• Work with Voya's product development team to scale and demonstrate cells from bench to pilot and production-intent systems.

Qualifications:

• Track record of developing novel electrochemical cell architectures, with hands-on experience building the physical stack hardware for flow-based systems (e.g. fuel cells, flow batteries, electrolyzers), specifically bipolar plates, flow fields, manifolds, gasket/sealing systems, and compression hardware.
• Proficiency in CAD-based mechanical design and DFM; comfortable moving from drawing to prototype to test stand yourself, not just handing off to a mechanical team.
• Mechanical background with exposure to electrochemistry preferred.
• Experience working with cross-functional teams, preferably for system or device development.
• Ability to operate in a fast-paced, start-up environment.
• Results-oriented with a strong sense of urgency.

Location: Hayward, CA. Full-time on-site.

What we offer:

• Competitive salary and equity compensation commensurate with experience
• Unlimited PTO
• 100% employer paid medical, dental, and vision coverage
• 401(k) plan
