ROLE DESCRIPTION The Cell Engineering team within the Technology group at Form is multidisciplinary and focused on delivering qualified battery cell designs that meet operational performance targets, at cost and with high reliability, from controlled processes on high-volume manufacturing lines for Form Energy's utility-scale multi-day energy storage system. We're hiring a Senior Mechanical Engineer to join our Cell Engineering Design team in Berkeley, CA. In this role, you will design plastic components for our iron-air battery cells. There will be a particular focus on injection molded plastics, and you will take the lead on design, test plan development, and validation testing of your components. This role will work closely with our manufacturing engineering team to define and support battery cell assembly process and equipment design. You will bring a willingness to become an expert in designing plastic components for manufacturing with injection molding, blow molding, thermoforming, or similar processes. You will also get hands-on experience with plastic joining methods, such as laser or hot-plate welding. This is an exciting opportunity to be part of scaling our multi-day energy storage system at Form and contributing to a sustainable future! WHAT YOU'LL DO: - Design molded plastic components for implementation in Form Energy’s iron-air battery cells - Apply first-principles engineering to design high-performance structural plastic and sheet metal components capable of withstanding static and dynamic mechanical loads - Own analysis, prototyping, and failure analysis efforts for plastic components - Fabricate first-of-a-kind plastic prototypes for mechanical fit checks and verification testing - Conduct validation testing to prove that designs meet critical requirements - Negotiate interface requirements with Battery Module and Electrode teams - Produce and release detailed 2D part and assembly drawings; define technical specifications (dimensional, functional, performance, manufacturing) WHAT YOU'LL BRING: - Degree in Mechanical Engineering, or related field; Bachelor's with 4+ years of industry experience - Experience with end to end product development, from concept to launch - Proficient in CAD and engineering analysis to drive design decisions - Strong data analysis skills, especially with respect to mechanical test results - Ability to thrive in
