Apple Inc.
Cupertino, California, United States Hardware
The people here at Apple don’t just create products — they create the kind of wonder that’s revolutionized entire industries. It’s the diversity of those people and their ideas that inspires the innovation that runs through everything we do, from amazing technology to industry-leading environmental efforts.Apple is looking for an experienced AC-DC Adapter Design Engineer to develop the next generation of high-density offline power supplies for our portable products. In this role, you will shape the architecture, performance, and reliability of adapters used by millions of customers around the world.Our team is collaborative, creative and passionate about what we do and the products we make.Come join us!
Description You will lead designs from early concept exploration through mass production, working hands‑on with simulations, prototypes, and validation in the lab. You will partner closely with mechanical, thermal, reliability, and manufacturing teams to deliver compact, efficient, and robust power solutions that meet demanding design goals and ship at high volume.This is a highly technical, individual‑contributor role for an engineer who enjoys solving complex problems, sweating the details, and taking full ownership of their design from first principles to factory ramp.
Responsibilities
Owning up AC-DC adapter design from architectural concept through mass production.
Performing detailed analysis, modeling, simulation, and hands‑on prototype bring‑up and validation in the lab.
Ensuring robust integration by working closely with mechanical, thermal, reliability, and manufacturing partners.
Driving key design decisions and root‑cause complex issues using strong analytical and problem‑solving skills.
Providing technical guidance to junior engineers while maintaining a primary focus on deep, hands‑on technical contribution.
Minimum Qualifications
Bachelor’s in EE or related field and a minimum of 10 years of industry experience
Experience with AC/DC power conversion topologies such as flyback, resonant converter and PFC design
Strong foundation in semiconductor and power electronics fundamentals, including silicon/GaN behavior, circuit analysis, control systems, magnetics, and embedded systems for power control
Proven ability to lead technical discussions and work effectively with cross‑functional mechanical, thermal, reliability, and manufacturing teams
Preferred Qualifications
Master's or Ph.D. in EE, with 5 years or equivalent of relevant working experience
Experience in high‑volume adapter development, with familiarity in manufacturing processes, tolerances, and production variation.
Mastery of offline AC-DC power supply design , including topology selection (flyback, forward, LLC, other Resonant topologies) and high efficiency PFC design with advanced analog/digital control techniques
Prior experience with a power supply module or adapter company is highly desirable
End‑to‑end design capability – analytical modeling, in‑depth simulation experience including parasitics , prototype bring‑up, validation, and design‑for‑manufacturing
Expertise in safety and EMC regulatory compliance, component selection, high‑density layout, and cutting‑edge efficiency optimization (including no‑load and light‑load techniques)
Deep understanding of thermals, mechanical integration, packaging, and power density tradeoffs
Experience in high‑frequency magnetic designs including magnetic material selection and various winding construction for power transformers and filters
Excellent communication and presentation skills
