About The Position

The Staff Engineer, Power Integrity develops new electrical systems/circuits for various applications. You will research system ideas and draw up plans for these systems, and capture them in schematics and system specifications. Other responsibilities will be testing, simulation, validating and qualifying the systems and make adjustments as needed. You will need to provide support throughout the manufacturing of the electrical systems that have been designed. The role will work in cross functional teams with other designers, customers, manufacturing engineering and project leadership to ensure robust and high quality product development. You will enhance designs with feedback from reviews in areas such as manufacturing, test, supply chain, reliability, industrial design and simulations.
