Capacitor Manufacturing Engineer
$105,000–$155,000 year
On-siteSan Leandro, California, United States
Job Summary
Lead the setup and commissioning of the capacitor manufacturing facility, including procurement and qualification of winding, impregnation, encapsulation, and high-voltage test equipment. Develop and optimize winding parameters for metallized polypropylene film systems, define tension and geometry for high-voltage pulse applications, and establish vacuum pressure impregnation processes to eliminate voids and maximize dielectric strength. Establish production acceptance testing for capacitance, dissipation factor, DC hipot, and partial discharge, while building quality controls to improve yield as production scales from pilot to high-volume manufacturing. Qualify suppliers for dielectric film and hardware, evaluate alternative materials for improved energy density, and implement automation across winding and testing to reduce unit cost.
Required Qualifications
- B.Sc or M.Sc in Electrical Engineering, Materials Science, Physics, Manufacturing/Process Engineering, or a related field
- 2+ years of hands-on experience in high-voltage film capacitor manufacturing, including winding, impregnation, encapsulation, and high-voltage testing
- Deep knowledge of polypropylene film dielectrics, metallization processes, and partial discharge physics at high field strengths
- Demonstrated experience with vacuum pressure impregnation (VPI) systems and epoxy/resin process chemistry
- Proficiency in high-voltage test methods, including capacitance bridge, tan δ, DC hipot, and partial discharge measurement (IEC 60270)
- Experience establishing or managing a manufacturing quality system (ISO 9001 or equivalent) for electrical components
- U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State
Desired Qualifications
- Prior experience at a pulsed-power capacitor manufacturer
- Familiarity with double-ended low-inductance capacitor architectures designed for pulse-discharge applications
- Experience with automated winding-machine programming and mechanical setup, including mandrel, tension control, and traversing
- Knowledge of capacitor life modeling under repetitive pulse stress, including voltage reversal, peak current, and dI/dt
- Familiarity with dielectric film casting or metallization processes
