Senior Engineer I, High Voltage Systems

Livermore, CA 94550

Must be a US Citizen or Green card holder.

The Senior Engineer I in the New Product Engineering team will be responsible for the design, development, and integration of the High Voltage systems for all new vehicles. This candidate will be the owner of the High Voltage systems specifications and drive them back to the suppliers to meet and exceed every aspect of requirements. You will have direct influence on vehicle electrical systems from concept through to manufacturing launch to field support.

You will be part of the team that develops the industry’s best-in-class zero emission bus. This role will focus on High Voltage (HV) design requirements and component evaluation and selection for the application, including HV cable assemblies, HV connectors, and HV circuit protection devices. Assignments are broad in scope and highly complex that require outstanding creativity, superior initiative, good judgement, and leadership skills combined with the willingness to do hands-on engineering. You will report directly to the Electrical Engineering Manager in New Product Engineering.
