About the role

Senior Materials Scientist focused on capacitor technologies (polymer, electrolytic, film, and safety capacitors) driving technology direction from concept to high-volume production across Apple product lines; serves as primary technical expert coordinating with suppliers and cross-functional teams.

Responsibilities

  • Own Apple's technology strategy across polymer, electrolytic, film, and safety capacitor families.
  • Bridge cross-functional teams with global capacitor suppliers across non-MLCC capacitor space (tantalum polymer, aluminum polymer, aluminum electrolytic, film, safety/Y-rated, and emerging electrochemical energy storage).
  • Predict component performance from supplier process choices (pellet morphology and sintering chemistry, oxide film formation kinetics, foil etch architecture, winding geometry, and conductive polymer chemistry) beyond datasheet specs.
  • Set Apple's technology direction across capacitor families 3+ years ahead of integration.
  • Collaborate with Passive Component Technologists, SI/PI teams, LOB EEs, and commodity managers across product lines.
  • Lead and influence development programs to successful and on-schedule delivery.
  • Demonstrate hands-on manufacturing awareness and factory-floor experience.

Qualifications

  • PhD in Materials Science & Engineering, Chemical Engineering, Electrical Engineering, Chemistry, or Physics with a minimum of 5 years of relevant professional experience in capacitor or passive component technologies.
  • Solid track record of leading passive component product development from concept to mass-production across multiple capacitor technology families
  • Experience with PFAS-free materials qualification and supplier transition management
  • Familiarity with MLCC ceramic dielectric R&D and supercapacitor / EDLC construction and reliability limits is a plus
  • In-depth knowledge of capacitor supply chains, including tantalum ore sourcing, aluminum foil markets, and polymer electrolyte supply base
  • Strong interpersonal skills and demonstrated cross-LOB technical collaboration
  • Hands-On Manufacturing Experience — a minimum of 5 years (preferably in a recent role) of direct, on-site factory floor experience with capacitor manufacturing processes is mandatory.
  • Cross-Disciplinary Knowledge — Familiarity with PDN and EMI filter circuit topologies, power supply design, IEC safety standards and regulatory frameworks (PFAS/REACH restrictions and supply-chain implications), and device-level reliability requirements across consumer electronics.
