A Hardware Bringup developer is primarily responsible for the initial setup, configuration, and troubleshooting of new hardware systems. They work closely with design and manufacturing teams to ensure that the hardware is functioning correctly, and that any issues are identified and resolved promptly. This involves writing and debugging low-level firmware, testing the hardware's functionality, and making necessary adjustments to the system's software. They also document their work for future reference and to aid in debugging. Their ultimate goal is to ensure that the hardware is ready and functioning correctly for the next phase of development or production.
