Capacitor Component Technologist

Join Apples innovative hardware team as a Capacitor Component Technologist where you will own Apples technology strategy across the polymer electrolytic film and safety capacitor families driving critical component solutions from initial concept to high-volume mass production across all Apple product lines.

In this senior role you will serve as the primary technical expert bridging Apples cross-functional teams with our global network of capacitor suppliers across the full non-MLCC capacitor space: tantalum polymer (including PFAS-free transition) aluminum polymer aluminum electrolytic film safety/Y-rated and emerging electrochemical energy storage technologies. You will be responsible for predicting component performance from supplier process choices pellet morphology and sintering chemistry oxide film formation kinetics foil etch architecture winding geometry and conductive polymer chemistry rather than relying on datasheet specifications and will set Apples technology direction across these families 3 years ahead of integration. You will work closely with our existing Passive Component Technologists SI/PI teams LOB EEs and commodity managers across iPhone iPad Watch Mac AirPods Vision Power Adapters and beyond. This is an exceptional opportunity for a scientist or engineer with deep materials science or electrochemistry expertise who is passionate about making a significant impact at Apple. This role requires approximately 1020% overseas travel.
