PMU Hardware Electrical Design Engineer

Apple • Cupertino, CA

4d

About The Position

Apple is seeking a hardware engineer to help develop custom mixed-signal integrated circuits for existing and future Apple product lines. The role involves designing complex test systems for state-of-the-art power supplies and contributing broadly to silicon development through simulation, software, bring-up, debugging, extraction, and analysis. The engineer will collaborate with a diverse, cross-functional team.

The position focuses on lab validation system design and development, PCB circuit design and review, hands-on hardware bring-up and debugging, and resolving engineering issues with cross-functional teams. Relevant systems may include LDOs, Buck converters, ADCs, DACs, operational amplifiers, FPGAs, and interfaces such as I2C, SPI, and SPMI. Experience with PCB manufacturing and assembly is also relevant.

Requirements

• Bachelor of Science degree.
• At least 3 years of relevant industry experience.
• Experience with hardware development from specification through bring-up and downstream support.
• Skill in component development and selection for schematic design.
• Ability to design or guide high-quality PCB layouts through fabrication and assembly.
• Familiarity with microcontroller, FPGA, or logic design and programming.
• Skill in an electronics lab environment using oscilloscopes, analyzers, function generators, automation hardware, power supplies, and electronic loads.
• Familiarity with power-quality, high-speed signal-integrity, and control-interface challenges.
• Excellent written, verbal, and communication skills, with a focus on teamwork and collaboration in a dynamic cross-functional environment.

Nice To Haves

• Master of Science in Electrical Engineering preferred.
• Knowledge of signal and power integrity, including PDN analysis.
• Prior experience with PCB CAD tools such as Cadence Allegro or Altium for multilayer board layout.
• Coding or automation experience in Python.

Responsibilities

• Design and develop lab validation systems using circuits such as LDOs, Buck converters, ADCs, DACs, operational amplifiers, and FPGAs, and control interfaces such as I2C, SPI, and SPMI.
• Perform circuit design, schematic development, analysis, layout, and review in a PCB environment.
• Conduct hands-on hardware bring-up and debugging in the lab.
• Drive debugging and resolution of engineering issues in collaboration with cross-functional teams.
• Contribute to silicon development through activities including simulation, software, bring-up, debug, extraction, and analysis.
• Support PCB manufacturing and assembly.
