The Apple Cellular Platform Software team is looking for a cross-disciplinary firmware engineer passionate about embedded this role you will work at the hardware/software interface and develop a range of low-level device drivers that directly control hardware such as CPUs memory DMA timers interrupts GPIOs I2C SPI and hardware loggers. There will be significant collaboration with hardware designers to understand improve and document hardware/software interfaces. Candidates must be knowledgeable and comfortable working across both hardware and software domains.

Design and develop Board Support Package (BSP) for RTOS and develop unit tests to ensure software pre- and post-silicon validation bring-up and performance software debugging using debuggers traces and crash software integration and manage branches with version control hardware specifications and assist with hardware factory testing and resolve critical issues on-site.

Bachelors degree in Electrical Engineering (EE) Computer Engineering (CE) or related field. n5 years of experience developing embedded firmware or kernel-mode in data structures and algorithms commonly used in an RTOS implemented in C/C and understanding of embedded system components such as CPUs memory hierarchies DMA timers interrupt control units and interconnect knowledge of real-time operating system (RTOS) concepts such as thread/process scheduling and synchronization exception handling virtual memory management and inter-process communication.

Experience with low-level hardware components (Memory DMA Timer GPIOs UART SPI I2C etc.).nExperience using Python as a support language for test automation data analysis and tool development to aid firmware validation and regression with pre-silicon bringup and validation on FPGA and emulation with cycle-accurate modeling and performance analysis.
