Supercapacitor Cell Engineer

Eaton’s Electronics division is seeking a hands-on Supercapacitor Cell Engineer to support the development of advanced cylindrical EDLC supercapacitor cells. This role is based in Pleasanton, CA, and relocation assistance is available for qualified candidates in the United States.

About the Role

This position requires an experienced engineer to own and execute the full cell development cycle, from design implementation and laboratory prototyping through process development, pilot builds, manufacturing transfer, and production ramp-up. The candidate will collaborate globally with internal engineering teams, suppliers, equipment vendors, and manufacturing partners, with travel up to 20%.

Responsibilities

• Lead hands-on development of cylindrical EDLC supercapacitor cells, including cell construction, prototyping, testing, process optimization, and manufacturing scale-up.
• Own the full cell development lifecycle, including cell design implementation, process development, equipment selection, pilot-line execution, manufacturing transfer, and production support.
• Develop repeatable cell assembly methods, process flows, work instructions, tooling, fixtures, and process controls for laboratory, pilot, and production environments.
• Define and optimize critical process parameters related to electrode handling, stacking or winding, electrolyte filling, sealing, fixturing, inspection, and cell assembly operations.
• Select, qualify, and optimize commercially available manufacturing equipment and tooling for pilot and production use.
• Support pilot-line development, process qualification, production readiness activities, and technology transfer to manufacturing sites.
• Collaborate with materials, quality, operations, test engineering, module engineering, and manufacturing teams to ensure successful product development and scale-up.
• Work with suppliers and equipment vendors to develop robust, scalable manufacturing solutions and improve process capability, yield, and reliability.
• Provide cell-level design constraints, tolerances, and manufacturing capability data to support module integration activities.
• Lead troubleshooting, root-cause analysis, failure investigations, and continuous improvement efforts related to cell design and manufacturing processes.
• Interface globally with suppliers, equipment vendors, manufacturing teams, and cross-functional engineering organizations. Travel domestically and internationally up to 20% as required.

Requirements

• Bachelor's or Master's degree in Mechanical Engineering, Manufacturing Engineering, Materials Science, or related technical discipline.
• Minimum 5 years of experience in manufacturing, process development, electrochemical device development, precision assembly, or related industries.
• Eaton will not consider applicants for employment immigration sponsorship or support for this position (e.g., CPT, OPT, STEM OPT, F-1 to H-1B, H-1B cap registration, O-1, E-3, TN status, I-485 job portability).

Preferred Qualifications

• At least 1 year of experience in supercapacitors, lithium-ion batteries, electrolytic capacitors, or similar electrochemical devices.

Skills

• Hands-on experience developing products or manufacturing processes from laboratory development through pilot builds and early production.
• Strong process development, manufacturing, tooling, fixturing, and assembly knowledge.
• Experience selecting, implementing, and optimizing manufacturing equipment.
• Experience supporting pilot-line development, production ramp-up, manufacturing transfer, and process optimization.
• Ability to work effectively with global suppliers, equipment vendors, and manufacturing partners.
• Strong problem-solving, communication, documentation, and cross-functional collaboration skills.
• Experience with cylindrical cells, winding, laser welding, electrode handling, separator handling, electrolyte filling, sealing, crimping, or related manufacturing processes.
• Experience working with manufacturing equipment vendors, particularly in Asia.
• Experience supporting manufacturing operations in Asia.
• Familiarity with DFM, GD&T, tolerance analysis, process capability studies, and manufacturing process control.
• Experience developing work instructions, process flows, control plans, and production documentation.
• Willingness to travel up to 20%, including domestic and international travel.

Pay

The expected annual salary range for this role is $117,000 - $172,000 a year. Salaries are based upon candidate skills, experience, and qualifications, as well as market and business considerations.

Benefits

Eaton provides various Health and Welfare benefits as well as Retirement benefits, and several programs that provide for paid and unpaid time away from work.
