# Capacitor Manufacturing Engineer - Company: [Fuse]() - Location: San Leandro, California - Team: Engineering / Technical Ops\. - Employment type: Full Time - Salary: $105K – $155K - Posted: August 19, 2026 ## Job description ## **About Fuse** We are building one of the most potentially consequential companies of the century. Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win. ## **About the Role** Fuse is establishing a dedicated in-house manufacturing facility for high-voltage pulsed-power capacitors. The program requires production of hundreds of thousands of 40–160 nF, 100 kV double-ended capacitors, previously produced only by a handful of specialized manufacturers worldwide. As the Capacitor Manufacturing Engineer, you'll bring deep hands-on expertise in high-voltage film capacitor fabrication to commission, qualify, and operate this facility from the ground up — a founding engineering role with direct impact on the core pulsed-power infrastructure. ## **Core Responsibilities** **Facility Setup & Process Engineering** * Lead the setup and commissioning of the capacitor manufacturing facility, including procurement and qualification of winding, impregnation, encapsulation, and high-voltage test equipment. * Establish the manufacturing process from raw film through finished, tested capacitor. **Film Winding & Dielectric Stack Assembly** * Develop and optimize winding parameters for metallized polypropylene (PP) film or film/foil electrode systems for high-voltage, low-inductance pulse applications. * Define winding tension, layer counts, geometry, and metallization strategies to improve performance and service life. **Vacuum Impregnation & Encapsulation** * Develop and qualify vacuum pressure impregnation (VPI) and encapsulation processes to eliminate voids, suppress partial discharge, and maximize dielectric strength. * Ensure terminal integration and mechanical robustness under repetitive discharge stress. **High-Voltage Testing & Quality Control** * Establish production acceptance testing, including capacitance, dissipation factor (tan δ), DC hipot, partial discharge, and pulse discharge life testing. * Build quality controls and statistical process tracking to improve yield and identify failure modes as production scales. **Materials & Supply Chain** * Qualify suppliers and establish material standards for dielectric film, metallization, electrodes, impregnants, and capacitor hardware. * Evaluate alternative materials and processes that could improve energy density, reliability, or temperature performance. **Continuous Improvement & Scale-Up** * Drive the transition from pilot production to high-volume manufacturing. * Implement automation across winding, testing, and packaging to improve yield, throughput, and unit cost. ## **Minimum 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. ## **Preferred 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 is a strong plus. ## **What We Value** * Give a shit. Build things you're proud of. * Take responsibility. If something is broken and you can fix it, fix it. See things through. * Move fast. Make decisions, learn quickly, and keep moving forward. * Think bigger. Simplify relentlessly. Don't default to the safe answer. * Disagree and commit. The best idea wins. Once a decision is made, we move. * Desire to win. This is hard. Expect intensity. We are here to win. * Plan B is to make Plan A work. ## **Benefits** * Medical, dental, and vision coverage. * Relocation assistance for roles that require it. * Flexible time off. Take what you need, no accrual tracking. * 2 weeks of paid time off built into the end of each year, subject to team and business needs. * Supportive leave of absence policies. * Paid leave for new parents. ## **ITAR Requirements** To conform to U.S. Government technology export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a 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. ## **Equal Opportunity** Fuse is an Equal Opportunity Employer; employment with Fuse is governed on the basis of merit, competence, and qualifications and will not be influenced by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, ancestry, immigration status, sexual orientation, gender identity, marital status, mental or physical disability, or any other legally protected status. ## Apply [Apply on Fuse]() Canonical job page:
