Circuit Design Jobs

Circuit Design is the process of designing electrical circuits to create a complete electronic system. A Circuit Designer is responsible for designing circuits, testing the board and components through simulations, troubleshooting any errors, and even prototyping the board by manufacturing a few before completing the entire circuit accurately. Through this intricate process, a Circuit Designer will be able to optimize the design with their expertise and creative talent to push out an efficient product.

Circuit Designers are knowledgeable engineers with a high level understanding of electronics engineering and components that can be used in a circuit. They also possess analytical skills as they must be able to calculate loads, power consumption and sophisticated circuit architecture that involves cause and effects to produce sound results. With extensive knowledge of hardware engineering, Circuit Designers are responsible for hardware selection, board sizing, and routing of signals.

Here's some projects that our expert Circuit Designer made real:

  • Automation systems built through electronic schematics
  • Electrical systems concepted through hand sketches
  • PCB designs implemented through industry standard software
