TouchID Electrical Engineering Tech Lead

The fingerprint you use to unlock your device, authorize a payment, or access your most private data-that's Touch ID. We're looking for an experienced electrical engineer to define and drive the next generation of Touch ID sensor designs, from early architecture through high-volume production. You'll make technical decisions that shape how millions of users experience security and responsiveness on Apple products. The Sensing Systems team develops MEMS, magnetic, and capacitive sensors that bring Apple products to life. Touch ID is central to how users trust and interact with their devices-and you'll own the electrical design decisions that make it possible.\n\nThis role puts you at the center of sensor development. You'll define module architectures, drive circuit design tradeoffs, and solve integration challenges that don't have obvious answers. You'll influence silicon requirements, shape system-level decisions, and own technical strategy from concept through mass production. When something isn't working, you'll dig in to understand why-and propose solutions that balance performance, power, manufacturability, and schedule.\n\nWe're looking for someone who combines deep analog expertise with the judgment to navigate ambiguity. You'll lead technical discussions with cross-functional partners, present recommendations to executives, and drive alignment when the path forward isn't clear. Your designs will ship in products used by millions. Strong analog circuit design fundamentals with experience owning designs through full product development cycles\nProficiency with circuit simulation (SPICE) and lab debug\nProficiency with MATLAB, Python, or similar for analysis and automation\nBS and a minimum of 10 years relevant industry experience Track record of leading technical discussions and driving alignment across disciplines\nExperience with capacitive or biometric sensing systems\nExperience with flexible PCB design and signal/power integrity analysis\nProficiency with statistical analysis tools (JMP, Tableau) for data-driven design decisions\nFamiliarity with FEA/simulation tools (COMSOL, ANSYS, Maxwell)\nExperience creating engineering specifications and translating system requirements into circuit implementations, making technical tradeoffs that balance competing constraints\nExperience influencing silicon or ASIC requirements from a system perspective
