Full Job Description
Who We Are Factorial Energy is a pioneering U.S.-based solid-state battery company driving the future of energy storage and electrification. Partnered with global leaders including Mercedes-Benz, Stellantis, Hyundai, and Kia, Factorial is at the forefront of developing next-generation e-mobility platforms for commercial, defense, and consumer applications—spanning electric vehicles (EVs), drones, eVTOL aircraft, power tools, marine systems, robotics, and more. The company has achieved multiple industry firsts, including being the first to power a demonstration vehicle with a global OEM (Mercedes- Benz) which achieved over 1,200 km (749 mi) of range, and the first to earn UN 38.3 certification for automotive-sized lithium-metal solid-state cells, the first to deliver B-samples of automotive-sized solid-state batteries to major OEMs. The Opportunity: Factorial is seeking an experienced Formation Process Engineer to lead the development, optimization, and mass-production support of lithium-ion battery formation (Formation) and grading (Capacity Sorting) processes for consumer electronics applications. This role covers the full process lifecycle — from R background in consumer battery (TWS, mobile, wearable) mass production lines strongly preferred. Deep understanding of formation fundamentals: SEI layer formation, gas evolution behavior, lithium deposition suppression, and electrolyte decomposition reactions. Proficiency in DOE, SPC, FMEA, and Six Sigma methodologies; Green Belt or Black Belt certification is a plus. Demonstrated experience in process transfer from R familiarity with PPAP/APQP workflows. Familiarity with major formation cycler platforms (e.g., Neware, Landt, Arbin, Basytec) and their programming logic; ability to independently troubleshoot equipment faults. Proficiency in electrochemical testing techniques: EIS, DCIR, self-discharge, and battery analysis software (BTS, Arbin, etc.). Skilled in JMP, Minitab, Python, or Excel for large-scale data analysi
