Senior Staff Mechanical Engineer, Advanced Product Development

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

Form's Advanced Product Development team is responsible for architecting and designing the next generation of our iron-air battery system — the cell, module, pack, and the support systems that keep them running reliably for decades in the field. We work ahead of our production programs, translating breakthrough electrochemistry and system requirements into mechanical designs that can scale to high-volume manufacturing.

We're hiring a Senior Staff Mechanical Engineer to develop the mechanical architecture and design of our next-generation battery and support systems. You will be responsible for developing systems which span thermal, fluid, and structural subsystems, and while resolving the toughest interdisciplinary trade-offs. This will include first principles modeling and analysis, first of a kind designs for experimentation and verification testing, and iteration into our next energy storage product. You'll work closely with battery scientists, materials engineers, electrical and controls engineers,and manufacturing engineers to make sure design decisions made today hold up at gigawatt-hour scale tomorrow.

Relocation assistance is available.

What you'll do:

• Own the mechanical design and architecture of next-generation energy storage systems (cell, module, thermal, fluid handling, structural) end-to-end, from concept through system verification

• Make and defend high-leverage trade-offs across subsystem interfaces — performance, cost, manufacturability, and reliability — where the right answer isn't obvious

• Build or direct first-principles analytical models that inform architecture decisions

• Lead first-of-a-kind prototype builds and test campaigns to validate system-level design choices

• Set technical direction for design-for-manufacturing and design-for-cost across the next-gen program, partnering with manufacturing engineering to plan the path from prototype to Form Factory-scale production

• Represent mechanical engineering in cross-functional architecture reviews with electrochemistry, controls, program management, and compliance

• Engage directly with critical vendors on early-stage development and sourcing strategy for novel components

• Champion safety, especially when introducing new lab processes, prototype hardware, or test methods

What you'll bring:

• Degree in Mechanical Engineering or related field; Bachelor's with 12+ years, or advanced degree with equivalent experience, in mechanical design of complex electromechanical or fluid/thermal systems

• Demonstrated track record owning system-level architecture — not just component design — including the trade-offs across thermal, fluid, and structural interfaces

• Deep first-principles grounding in thermo-fluid systems, with experience translating analytical models directly into design decisions

• Experience taking a product from early-stage concept through to manufacturing and driving development strategy along the way

• A record of technical leadership and mentorship — influencing engineering direction and raising team capability

• Comfort operating with significant ambiguity in an early-stage environment ramping toward production, with the urgency to hit demanding schedule targets

• Strong ownership mentality to do what it takes; eager to roll up sleeves and get hands-on with hardware when necessary

• Experience in energy storage, batteries, or another safety-critical, highly regulated hardware industry is a strong plus
