Job description

Are you ready to build America’s energy future? Form Energy is an American manufacturing and energy technology company. We’re revolutionizing energy storage with cost-effective, multi-day technology designed to keep the electric grid secure and reliable, even during extended periods of stress. By strengthening the electric system and reimagining what’s possible, we’re giving clean energy a whole new form!

In recent years, Form Energy has earned a number of accolades, including being named by TIME as a “Best Invention”, MIT Technology Review as a “Top Climate Tech Company To Watch”, and Fast Company as “One of the Next Big Things In Tech”. We are making rapid progress on our mission of delivering energy storage for a better world, and our team is growing just as rapidly to meet demand. We have signed contracts with leading electric utilities across the United States and production of our iron‑air batteries is underway at our first high-volume manufacturing facility in West Virginia.

Working for Form Energy is more than just a job, it’s a chance to be part of something extraordinary. And now - right as we significantly scale up battery manufacturing - might be the most exciting moment in the company’s history to join. We are assembling a team of highly talented and driven individuals across the country. Driven by our core values of humanity, excellence, and creativity, our team is determined to deliver on our mission and transform the energy landscape for the better.

Feeling energized to make a meaningful impact on the world? Then keep reading - you’ve come to the right place.

Role Description

The Mechanical Engineering team at Form is focused on designing the battery cell, module, and full pack system that forms the foundation of our innovative utility‑scale multi‑day energy storage system. We strive to deliver designs that are optimized for performance, quality, reliability, and cost for high‑volume manufacturing at Form Factory.

We’re hiring a hands‑on Senior Mechanical Design Engineer to own the design of subsystems within our electrolyte & water management system. This is the circulatory system of Form’s iron‑air battery technology and it is critical to the system’s successful operation. In this role, you will play a key role in the product definition and detailed design stages, first‑of‑a‑kind build activities, vendor engagement, and design for manufacturing. You can expect to work on prototyping efforts across the company, build and validate models of our system, drive us through a series of design releases, and work closely with a cross‑functional team of chemical, electrical, and mechanical engineers to design, prototype, and test the storage systems. You will be responsible for design validation before the final manufacturing release.

Relocation assistance is available.

What you’ll do:

• Design, prototype, and test the electrolyte & water management system to meet critical performance requirements

• Use first principles of fluid flow to optimize system design and inform design architecture decisions

• Prepare and lead design reviews and trade studies covering your system components

• Fabricate and test first‑of‑a‑kind prototypes to validate system design choices

• Conduct critical vendor engagements and collaborate with manufacturing engineers to transition system designs from prototype to high‑volume production

• Collaborate with the Electrical and Firmware teams to optimize actuator and sensor integration

• Work with the battery cell and systems team to co‑develop auxiliary systems

• Champion safety, especially in the development of new laboratory processes

What you’ll bring:

• Degree in Mechanical Engineering or related field; Bachelor’s with 5+ years of industry experience in mechanical design of equipment, liquid, or gas handling systems

• Understanding of first‑principles modeling and design and experience optimizing designs for manufacturing and cost‑down

• Experience working in a manufacturing environment or with contract manufacturing vendors

• Demonstrated experience optimizing mechanical design, balance‑of‑plant systems, and interdisciplinary interfaces of fluid systems

• Direct experience in product development within an early‑stage environment
