Senior Mechanical Engineer, R&DResearch & Development * Somerville, MA On-site

Are you ready to build America's energy future? Form Energy is an American manufacturing and energy technology company focused on energy storage to keep the electric grid secure and reliable.

Form Energy is hiring a mechanical engineer to drive mechanical design, prototyping, and validation of electrochemical cell architectures for our next-generation technology. As part of the R&D team, you will own experimental hardware from concept through validation, partnering closely with other mechanical engineers, battery engineers, and materials scientists to de-risk early-stage product concepts. This is an exciting opportunity to contribute to a fast-moving company with breakthrough technology and an important mission.

Relocation assistance is available.

• Design, build, and validate prototype electrochemical cell architectures and experimental setups, translating functional requirements into hardware that works
• Own the iterative design cycle end to end, ensuring mechanical and electrochemical requirements are met and refine designs based on experimental results, in close partnership with battery scientists and electrochemists
• Select and carry out engineering analyses to support designs (e.g., hand calculations, FEA, CFD, tolerance stack-ups, and materials testing), using judgment to fit the method to the problem
• Drive prototyping in-house and through external manufacturers, and manage vendor relationships
• Maintain the design record through written documentation, 3D CAD files, engineering drawings, and test data
• Identify design gaps and opportunities early, propose creative solutions, and communicate proactively across engineering and science teams
• Coordinate and mentor junior engineers and technicians on shared prototyping efforts

• Bachelor's + 4 years work experience;
  Master’s + 1 year; or PhD in Mechanical Engineering or related field
• Demonstrated depth across the full mechanical design cycle, from concept through prototyping and validation, with a track record of owning designs independently
• Proficiency in computer-aided design (CAD), including engineering drawings and geometric dimensioning and tolerancing
• Hands-on experience with metal and plastic prototyping techniques (e.g., laser cutting, 3D printing, machining, welding), and judgment about in-house vs outsourced work
• Strong engineering analysis skills (e.g., FEA, CFD, tolerance analysis, or materials testing) and ability to select the right method for a given problem
• Excellent communication and organizational skills

Compensation Range: $128,662 - $168,844
