DC-DC Power System Design Engineer

This is an excellent opportunity to work on the forefront of new power management technologies with the exemplary company consistently bringing innovations in the industry. In this position, you will work with teams developing innovative products used by millions of people. Your role on the team involves implementing the 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. - Work with system and power architects on CPU/GPU computer system architecture investigations using single-phase and multi-phase dc-dc voltage regulators. - Apply technical rigor to analyze design tradeoffs including system performance, power consumption & efficiency, physical size, cost, carbon footprint and scalability. - Own power circuit schematic and BOM. Work with PCB layout team. - Develop new components with integrated circuit, capacitor and inductor vendors. - Validate prototypes and perform competitive bench marking through lab testing. - Provide technical support for production issues debug and resolutions. - Conduct DC-DC power seminars and training for multi-functional teams. - Provide technical leadership and mentor junior DCDC engineers. - Spearhead innovation via exemplary behavior and collaboration.

Electrical / Computer engineering degree with >5 years of relevant work experience, e.g. in consumer electronics or semiconductor companies. Understanding of single- and multi- phase DC-DC regulators, control loops, operating modes, thermals, efficiency, passive components and power delivery network. Ability to predict performance using circuit simulators, e.g. Spice and Simplis, optimize schematic and PCB layout, validate performance by lab measurements. Occasionally travel in the US and overseas to provide factory or vendor support.

Highly motivated, self-starter, able to work well with multi-functional teams in dynamic work environment. Strong analytical skills and ability to guide critical investigations and decisions. Experience with multi-channel power management integrated circuits. Background in analog, digital or power integrated circuit design. Track record of innovations, e.g. patents or publications. Code development skills, e.g. Python, Matlab, Math-Cad. Experience with digital hardware design such as microcontrollers and digital interfaces (such as I2C, SPI, SPMI, etc)
