R&D Electric Motor Controls Engineer (2021)

Location: 

Saginaw, MI, US

Division:  North America (NA)
Req ID:  42975

Overview

We are looking for a highly self-motivated individual who is ready to take on a technology development and innovation role. The candidate should possess good attention to detail, good mentorship ability, be creative, and possess good time management skills. This position is for research and development, including modeling, simulation, analysis and verification, of electric drive systems, and enforcing the technology development process for various technical projects from research through production implementation. This position allows the candidate to assist in advancing the motor control technology roadmap that both supports the existing Nexteer product line and enables expansion for the next generation products. The candidate will also be responsible for coordinating cross-functional projects with multiple technical groups within the organization, support the organization for all areas of motor control development and develop new motor control system algorithms individually.

This role is focused towards high voltage, high power electric motor drive systems for electric and hybrid vehicle propulsion applications. The ideal candidate would possess strong technical skills that encompass multiple disciplines including familiarity with electromagnetics, electric machine design, and electric motor drive control system modeling and design.
