Electrical and electronics engineers design, develop, test, and maintain electrical and electronic devices. Many of these devices create power, help people talk to one another, or provide lighting for buildings.

Engineers use computer-aided design (CAD) systems and engineering software to design devices and equipment. They factor in safety, environmental impact, and energy usage. They calculate costs and select materials that follow manufacturing standards.

Engineers work with a team to build systems and products they have designed. They oversee and make sure workers build the product correctly. During construction, engineers identify problems and solve them.  They plan the layout of equipment and lines. They make sure products meet specifications, safety standards, and codes.

After construction, engineers test equipment and provide ongoing maintenance if needed. They also evaluate devices and systems already in use and make recommendations for repair or redesign.

Electrical engineers design electrical equipment such as:

• Electric motors
• Radar and navigation systems
• Communications systems
• Power generation equipment

Electronics engineers design and develop electronic equipment such as:

• Broadcast and communications systems
• Global positioning systems (GPS)

Sometimes engineers design small components for large systems, such as power inverters for solar energy systems.

Some electrical and electronics engineers work for green technology companies where they may develop products that use less power. For example, in the car industry electrical engineers build efficient parts for electric cars.
