Sr. Simulation & Analysis Engineers – Battery & Charger Development

Milwaukee Tool•Brookfield, WI

1d•Onsite

About The Position

Milwaukee Tool is hiring a Sr. Simulation & Analysis Engineer for battery and charger development in Brookfield, Wisconsin. The role leads battery-pack and electro/thermal design, develops best practices for pack-level modeling and simulation, and balances mechanical, electrical, and fluid-flow simulation to evaluate pack heating and cooling. It also involves identifying, developing, and maintaining simulation tools to predict battery-pack performance, thermal behavior, and failure modes, and using results to guide design decisions that improve performance, reliability, and safety. The engineer establishes pack-level thermal test regimens, delivers data analysis to support design recommendations, and leads the development and implementation of test plans and project resources to correlate and improve simulation results. The role presents technical content, collaborates with design engineers to incorporate simulation early in the design process, and may manage project team members. It leads engineering analyses including electro-mechanical simulation, fluid and mass transfer, Design of Experiments, and statistical data analysis. Duties also include vibration analysis and testing, and use of additional test capabilities such as IR cameras, thermocouples, laser vibrometers, and strain gauges. Domestic and international travel of 10% is required.

Requirements
