Engineering Technician, Cell

Stealth-mode Battery StartupSan Jose, CA
Onsite

About The Position

We are a stealth-mode battery startup developing cutting-edge battery technology. Our mission is to revolutionize battery technology to accelerate the global transition to clean energy. By leveraging innovative materials, advanced manufacturing techniques, and next-generation energy storage architectures, we are building the future of sustainable energy. We are seeking a hands-on Engineering Technician to support the assembly, testing, and development of next-generation battery cells. This role will work closely with engineers and scientists to build prototype and pilot-scale cells, execute manufacturing processes, collect data, and help scale production from development into commercialization. Unlike large-scale automated manufacturing environments, this position involves significant manual assembly, process experimentation, and problem-solving. The ideal candidate enjoys working with their hands, follows detailed procedures, and is excited about contributing to the growth of a rapidly evolving battery technology company.

Requirements

  • High school diploma or GED required.
  • 3+ years of experience in manufacturing, assembly, laboratory operations, battery manufacturing, electronics assembly, semiconductor manufacturing, medical device manufacturing, or a related technical environment.
  • Demonstrated mechanical aptitude and ability to work with hand tools and precision equipment.
  • Basic computer skills and familiarity with production records, spreadsheets, or data entry systems.
  • Takes ownership of responsibilities and delivers work with a high degree of precision and quality.

Nice To Haves

  • Experience assembling lithium-ion batteries, battery cells, fuel cells, or other energy storage products.
  • Familiarity with dry room, cleanroom, or controlled manufacturing environments.
  • Ability to read engineering drawings, assembly instructions, and technical documentation.
  • Degree or technical certification in manufacturing technology, engineering technology, electronics, chemistry, or a related field.
  • Experience participating in process improvement or manufacturing scale-up efforts.

Responsibilities

  • Assemble battery cells and related components according to engineering specifications, work instructions, and quality standards.
  • Perform battery cell assembly processes including electrode preparation, stacking, winding, tabbing, sealing, electrolyte filling, and formation activities.
  • Operate laboratory, pilot-line, and production equipment used in battery cell manufacturing.
  • Conduct in-process inspections and quality checks to ensure cells meet performance and reliability requirements.
  • Record manufacturing data, process parameters, and observations accurately.
  • Support engineers with prototype builds, process development activities, and manufacturing trials.
  • Troubleshoot assembly, equipment, and process issues and communicate findings to engineering and operations teams.
  • Maintain clean, organized, and safe workspaces, including dry room and controlled-environment areas.
  • Prepare materials, consumables, and tooling needed for daily production and development activities.
  • Assist with inventory tracking, material handling, and production readiness activities.
  • Follow all safety, environmental, and quality procedures.
  • Contribute to continuous improvement efforts to enhance yield, quality, and manufacturing efficiency.

Benefits

  • Opportunities for professional growth and career advancement.
