Senior Battery Electrical Engineer

Unique Systems Design • Contract • Lake Orion • 3m ago

The Senior Battery Electrical Engineer is responsible for the design, development, and execution of core battery electrical system components and assemblies. They are responsible for defining, documenting, designing, and releasing critical electrical systems and interfaces within the battery pack (e.g., cell interconnections and sensing circuitry, High-Voltage (HV)/High-Current (HC) interfaces) and overseeing validation of those components and assemblies. This role is responsible for the Battery Management System (BMS) Hardware.

The Senior Battery Electrical Engineer is comfortable applying technical knowledge to innovative designs, driving resolution of challenges, and taking ownership of new product development activities.

Apply technical knowledge to the on-time delivery of work products through the product development life cycle for each project.
Own the design and development of efficient designs for components and sub-assemblies. Work products include the design and release of HV Layouts, Grounding Strategies, Contactors, Fuses, Resistors, and Cabling.
Work in concert with Manufacturing Engineers in the development of processes and tools supporting manufacturing and assembly.
Component definition, sizing, selection, and design of cell electrical interconnections and bussing, module and pack HC and HV electrical interconnections and bussing, fusing, sensing, and control circuitry.
Assist the commodity responsible engineer with BMS Hardware and its interfaces to relevant battery subsystems.
Work closely with Systems Engineers and Computer-Aided Engineers (CAEs) to prove out design concepts prior to pack prototype builds.
Act as a mentor and advisor to Design Release Engineers (DREs) on the team.
Key contributor to electrical system Design Failure Mode and Effects Analysis (DFMEAs), Process Failure Mode and Effects Analysis (PFMEAs), Design Verification Plan and Reports (DVP&Rs), and Product and Process design reviews.
Lead supplier evaluation and development for responsible commodities, in collaboration with purchasing.
Support prototype system builds by ensuring parts are on time and that issues are resolved in a timely manner.
Adhere to federal and state regulations.
Adhere to all company policies, processes, and procedures.
Performs other duties as requested, directed, or assigned.
Predictable and reliable attendance.

Position Qualifications

Minimum of five (5) years of experience in HV (>350V) electrification product design or product development.
Proficient in root cause analysis and resolution.
Adept in data processing and statistical analysis.
Effective communicator, capable of concisely presenting highly technical data to internal & external customers, as well as effectively communicating with suppliers.
Experience with the design, handling, and manufacturing of HV lithium-ion battery systems and components such as busbars, resistors, shunts, connectors, and fuses.
Experience in Printed Circuit Board Assembly (PCBA), Hardware (HW), Electronic Control Unit (ECU) development and troubleshooting, with BMS-specific experience preferred.
Demonstrate understanding of the system operating principles and software functions of said ECU(s) to be an effective interface to Systems and Software Engineering counterparts.
Knowledge of Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) design standards and ability to interpret and troubleshoot test results.
Educated on common automotive and industry standards.
Familiar with the product design process.
Self-motivated problem solver; pays attention to the details.
Challenges the status quo and strives for continuous improvement.
