A Firmware Engineer designs, creates, and updates firmware, which is the software programmed into hardware devices. They work closely with hardware engineers to align hardware and software compatibility, often developing software for embedded systems or microcontrollers. They use languages like C or C++, and must understand hardware schematics and components. They need to troubleshoot and resolve issues that arise during development, testing, and post-production stages. Additionally, they ensure the firmware is efficient, reliable, and secure. They often work on tech products such as smartphones, medical devices, or automotive systems.
