DC-DC Power System Design Engineer

This is an excellent opportunity to work on the forefront of new power management technologies with Apple, a company consistently bringing innovations to the industry. In this position, you will work with teams developing innovative products used by millions of people. Your role involves implementing advanced DC-DC power design for Apple's next generation Mac platforms, covering desktop designs, portable computers, and other future Mac products.

As a DC-DC power system designer, you will be driving innovative power circuit designs and system level partitioning from concept investigation and design through successful product level implementation. Your responsibilities include:

• Working with system and power architects on CPU/GPU computer system architecture investigations using single-phase and multi-phase dc-dc voltage regulators.
• Applying technical rigor to analyze design tradeoffs including system performance, power consumption & efficiency, physical size, cost, carbon footprint, and scalability.
• Owning power circuit schematic and BOM, and working with the PCB layout team.
• Developing new components with integrated circuit, capacitor, and inductor vendors.
• Validating prototypes and performing competitive benchmarking through lab testing.
• Providing technical support for production issues debug and resolutions.
• Conducting DC-DC power seminars and training for multi-functional teams.
• Providing technical leadership and mentoring junior DCDC engineers.
• Spearheading innovation via exemplary behavior and collaboration.

This role requires an Electrical / Computer engineering degree with over 5 years of relevant work experience, preferably in consumer electronics or semiconductor companies. You should have a strong understanding of single- and multi-phase DC-DC regulators, control loops, operating modes, thermals, efficiency, passive components, and power delivery networks. The ability to predict performance using circuit simulators (e.g., Spice and Simplis), optimize schematic and PCB layout, and validate performance by lab measurements is crucial.

Preferred qualifications include being highly motivated, a self-starter, and able to work well with multi-functional teams in a dynamic work environment. Strong analytical skills, experience with multi-channel power management integrated circuits, background in analog, digital, or power integrated circuit design, and a track record of innovations (e.g., patents or publications) are highly valued. Code development skills (e.g., Python, Matlab, Math-Cad) and experience with digital hardware design such as microcontrollers and digital interfaces (I2C, SPI, SPMI, etc.) are also preferred.

Occasional travel within the US and overseas to provide factory or vendor support may be required.
