About Computer Hardware Engineers

Electrical Engineers design, develop, and test electrical systems and components including power generation and distribution systems, electronic circuits, communication systems, control systems, and embedded systems. The field spans power engineering, electronics, signal processing, telecommunications, and embedded systems design. Power engineers design high-voltage transmission systems, substations, and electrical distribution networks. Electronics engineers design printed circuit boards, analog and digital circuits, and microelectronic devices. Embedded systems engineers develop firmware and hardware for microcontrollers in products ranging from appliances to aerospace systems. Control engineers design feedback and automation systems for manufacturing, robotics, and process control. Electrical engineers use simulation tools such as MATLAB, Simulink, SPICE, and Altium Designer, and must translate theoretical designs into physical hardware that meets performance, reliability, and regulatory requirements. They work in energy, manufacturing, telecommunications, aerospace, automotive, and consumer electronics industries. PE licensure is required for power systems engineers working on public utility projects.
