Embedded software engineers design, develop, and test software that controls embedded systems - devices dedicated to performing specific tasks. Their scope ranges from programming microcontrollers, designing real-time systems, interfacing with hardware, optimizing code for performance and power consumption, to debugging complex system-level issues. They work closely with hardware engineers to define system architecture and often need to understand hardware principles and electronics. The scope of their work can span various industries, including automotive, telecommunications, healthcare, and consumer electronics, among others. In addition, they may also be involved in tasks such as developing device drivers, firmware upgrades, and creating documentation for their designs.
