Senior Battery Systems Test Engineer

Senior Battery Systems Test Engineer

Lake Orion, Michigan

Job Summary:

The Senior Battery Systems Test Engineer will be responsible for supporting bench and customer testing for the development of high-voltage automotive battery packs. The Battery Systems Test Engineer will be responsible for working cross-functionally, (including systems engineering, validation, testing, product engineering, software engineering, and program management teams), to define and execute development testing designed to verify system-level requirements at a battery pack; instrument DUTs for CV testing; create problem reports and drive resolution of these problems; and collect, process, analyze, and communicate test data to internal and external customers. The role is vital to the success of the organization as the Battery Systems Development Engineer develops the battery systems to reduce design iterations during the DV phase.

Responsibilities:

• Leads the development of the battery system verification test plans and budgets; executes the test plan for the development of battery pack systems to ensure compliance with customer requirements
• Lead and drive problem resolution of issues identified during testing, utilizing the cross- functional engineering team
• Statistically analyzes the subsequent test data, creates tables/charts, prepares/presents the test reports to internal and external teams, supports correlation to virtual validation efforts
• Collaborates with lead system engineers to integrate project-specific system verification test plans and test cases into the requirement management system; updating them, and their traceability.
• Update the team and the requirement management system with test results and support project teams to track the status.
• Supports engineering in the evaluation of projects and technical risk analyses to drive attention and focus of testing and analysis on the highest risk items that need verification; such as DFMEA outputs.
• Supports and consults validation team on higher risk design validation testing items.
• Leads the development of system inspection requirements for end-of-line testing, from quality control plan
• Collaborates with other key functional engineering groups to support and consult with them on their verification-related tasks.

Required Qualifications

• Bachelor’s degree in Mechanical, Electrical, or Systems Engineering (or equivalent).
• Minimum of five (5) to seven (7) years of engineering experience in systems testing, system verification, or HIL testing of lithium-ion battery or EV project.
• Experience developing and executing testing on CAN-based systems either on bench or in- vehicle.
• Experienced with the handling of both low and high-voltage lithium-ion battery systems.
• Expert communicator, capable of concisely presenting highly technical test data to internal and external customers, and cross-functional teams.
• Ability to travel and work flexible hours as needed (less than 10% travel on average).
• Experience with Microsoft office tools (Word, Excel, and PowerPoint).
• Basic lab/shop skills (multimeter, power tools, etc.)
• Experience using Minitab, MATLAB/Simulink, and/or other comparable statistical analysis software, particularly with lithium-ion test data.

Preferred Qualifications

• Master’s degree in Systems Engineering or Engineering Degree in Energy Systems Engineering.
• Minimum of seven (7) years experience in lithium-ion battery systems testing on production battery pack programs.
• Product experience with Li-Ion batteries, battery pack design, electric vehicles, power systems, alternative energy systems, electronic control units (ECUs), battery management systems (BMS), MEMS, and sensors.
• Educated on common lithium-ion cell, module, and battery pack test certifications.
