What Does an Electronic Engineer Do?

Electronic engineers refer to senior engineering and technical personnel who are engaged in research, teaching, product design, technological development, production and management of various types of electronic equipment and information systems. Generally divided into hardware engineers and software engineers. The hardware engineer is mainly responsible for circuit analysis and design; and uses the computer software as a tool for PCB design. After the factory PCB is manufactured and the electronic components are soldered, the test and debugging are performed. The software engineer is mainly responsible for writing and debugging embedded programs such as MCU, DSP, ARM, FPGA and so on. FPGA programs are sometimes the domain of hardware engineers.
