Senior Firmware Engineer
Summary
Senior firmware engineer on Apple's Accessories team, developing embedded firmware in C for next-generation Apple and Beats accessory hardware. Day to day: hardware bring-up and chip-level debugging, prototyping on low-power ARM Cortex-M microcontrollers, bus interfaces like I2C/SPI/USB, and design characterization, test, and validation.
The Accessories team is seeking a highly motivated Firmware Engineer with a strong foundation in engineering principles and a deep passion for new technologies. In this role, you will be at the forefront of researching, developing, and innovating solutions for the next generation of Apple and Beats accessory products. You will play a critical role in the product development lifecycle, turning early concepts into fully realized, world-class devices. This role requires an energetic individual who thrives in a fast-paced, rapid-development environment and is ready to innovate.
The Firmware Engineer will be part of a team that architect, design, develop, and maintain hardware and software systems for Accessory products. This engineer will also perform characterization, test and validation of each design; analyze results and create reports/presentations when needed.
This role requires an energetic and motivated individual ready to innovate. Experience in a quick paced rapid development group is highly desired.
