iPhone System Engineer – Power & Charging

The iPhone Division is seeking a talented Power u0026 Charging Systems Engineer to join a top-notch engineering team developing next-generation iPhone products. This individual contributor role covers power management subsystems and wired/wireless charging solutions from circuit and IC definition through thermal management and charging will work closely with Apples internal hardware/software teams contract manufacturer teams and IC vendor teams across all stages of development. We expect familiarity with portable low-power consumer electronics and a commitment to delivering high-quality high-volume products.

As a power and charging systems engineer you are expected to bridge analog circuit design and system-level architecture. This requires a solid understanding of power conversion topologies (switching regulators linear regulators switched capacitors) charging systems (wired and wireless) battery management and high-efficiency DC-DC converters. You should also be comfortable addressing system-level challenges including power sequencing interference mitigation PCB layout optimization thermal management and digital interface design.
