A CCS (Code Composer Studio) developer designs, develops, tests, and debugs embedded software applications using Texas Instrument's integrated development environment, Code Composer Studio. They work with microcontrollers and microprocessors to create real-time applications, often for systems with strict timing or resource constraints. They also optimize code for performance, size, and power consumption. CCS developers work closely with hardware engineers to integrate and test software with the hardware. They also troubleshoot and fix software bugs, maintain code documentation, and may contribute to system architecture design. They need a deep understanding of embedded systems, programming languages like C or C++, and debugging tools.
