iPhone System Engineer – Power & Charging
Summary
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.
Description
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.
Responsibilities
- Plan system and subsystem power and charging architecture, including IO trees and charging policies (wired and wireless)
- Distill system requirements into IC definitions and write specifications; draft and review IC datasheets
- Conduct IC design reviews and manage bug tracking throughout the full design cycle
- Drive and participate in system-level discussions on power management, charging, and battery management
- Participate in IP development, schematic, and layout reviews
- Lead or assist in prototype bring-up and lab debugging
- Perform bench verification of functional and parametric characteristics, including automation scripting
- Conduct signal characterization across power and charging domains
- Provide production test support, manufacturing support, and field issue resolution
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
