Fuse Energy
Capacitor Manufacturing Engineer
About this role
Fuse is building an in-house manufacturing facility for specialized high-voltage pulsed-power capacitors (40–160 nF, 100 kV) and seeks a Capacitor Manufacturing Engineer to commission and operate this facility from the ground up. You'll own the complete process—from equipment qualification and film winding to impregnation, testing, and scale-up—drawing on deep expertise in high-voltage film capacitor fabrication.
What you'll do
- Commission and qualify winding, impregnation, encapsulation, and high-voltage test equipment for the new facility
- Develop and optimize film winding parameters for metallized polypropylene and film/foil systems, including tension, geometry, and metallization strategy
- Develop and qualify vacuum pressure impregnation and encapsulation processes to eliminate voids and suppress partial discharge
- Establish production acceptance testing including capacitance, tan δ, DC hipot, partial discharge, and pulse discharge life testing
- Qualify suppliers and material standards for dielectric film, metallization, electrodes, impregnants, and hardware
- Drive transition from pilot to high-volume production, implementing automation and continuous improvement
What they're looking for
- High-voltage film capacitor manufacturing and design
- Polypropylene dielectrics and metallization processes
- Vacuum pressure impregnation (VPI) and resin chemistry
- High-voltage testing methods (capacitance bridge, tan δ, DC hipot, partial discharge per IEC 60270)
- Partial discharge physics and dielectric strength analysis
- Manufacturing quality systems (ISO 9001) and statistical process control
- Automated winding machine programming and mechanical setup
- Supply chain qualification and materials evaluation
