Form Energy is seeking a Principal Manufacturing Engineer to lead the development and deployment of battery cell assembly manufacturing systems at their high-volume production facility in Weirton, WV. This is a hands-on technical leadership role focused on scaling iron-air battery manufacturing from prototype to full production. You will own the complete manufacturing engineering ecosystem, including equipment selection, process design, and deployment. Key responsibilities include: developing manufacturing workstations from manual benchtop stations to fully automated integrated systems; providing Design for Manufacturability (DFM) feedback to design engineers; selecting and partnering with equipment integrators; installing, commissioning, and qualifying new equipment; designing robust processes for safety, uptime, and quality; debugging and resolving time-sensitive manufacturing issues; and collaborating across design, supply chain, operations, safety, and facilities teams. This role demands 18+ years of equipment or manufacturing engineering experience, ideally in electro-mechanical assembly. Required skills include direct experience purchasing and setting up automated manufacturing equipment, writing Standard Operating Procedures, providing DFM/DFA feedback, and hands-on build/test capabilities. A BS in Mechanical, Manufacturing, Industrial, or Electrical Engineering is required. Experience with plastic and metal welding, automated assembly, inspection, test systems, human-assist automation, automation programming, and MES systems is valued but not required. Form Energy is a venture-backed climate tech company revolutionizing energy storage with cost-effective, multi-day iron-air battery systems. Named a TIME Best Invention and MIT Technology Review Top Climate Tech Company To Watch, the company is rapidly scaling production. The Weirton facility is a 550,000-square-foot hub for high-volume battery production. Relocation assistance is available. The role is based on-site at Form Factory 1 in Weirton, an easy commute from Pittsburgh, PA.
