A principal electrical engineer serves as a project manager for electrical-related building or construction projects. In this role, your job duties may include designing electrical devices, ensuring proper installation, inspecting completed electrical work, and providing work estimates. You may also supervise a staff of junior engineers, overseeing their work, and ensure that the project is completed within the allotted timeframe and budget. Principal electrical engineers are often the liaison between the engineering team and upper management. You must create reports and communicate regular updates on the status of each project to ensure each stage is meeting deadline expectations.
