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.
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.
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
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
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
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
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
Drive the transition from pilot production to high-volume manufacturing
Implement automation across winding, testing, and packaging to improve yield, throughput, and unit cost
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
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
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
Compensation: $105K - $155K per year
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
Compensation: $105K - $155K per year
