What are the responsibilities and job description for the iPhone System Engineer – Power & Charging position at Apple?
The iPhone Division is seeking a talented Power & 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 policy.
You will work closely with Apple's 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.
Minimum Qualifications:
BS/MS in Electrical Engineering or equivalent
3 years of industry experience
Strong EE fundamentals: power converters, op-amps, filters, ADCs/DACs, output drivers
Hands-on experience with lab equipment (oscilloscope, power analyzer, digital meter, etc.) and circuit prototyping and debugging
Strong verbal and written communication skills
Preferred Qualifications:
Experience in one or more of the following areas: switching mode power supply, linear power supply, PMIC, system power architecture, wired/wireless charging, high-efficiency DC-DC converters, battery management (charger, gas gauge, BMU), camera flash/laser drivers
Experience prototyping, bringing up, validating, and debugging circuits and products in the lab
Experience collaborating across hardware, software, mechanical, and thermal engineering disciplines
Strong organizational skills with the ability to manage multiple priorities and drive complex tasks to completion
Effective presentation skills and comfort working with IC vendors and contract manufacturers
MS or PhD in Electrical Engineering or equivalent
