Job Description

Job Summary:

The Senior Electrical Systems Engineer leads the development of battery system electrical requirements, architecture, and analysis, using an interdisciplinary approach. This role drives early integration of electrical systems, defines system architecture and schematics, and supports them throughout the full project lifecycle. It involves identifying technical risks, contributing to design development, and ensuring system performance through testing and analysis. The engineer collaborates closely with cross-functional teams—including BMS, design, manufacturing, and validation—to support simulation, troubleshooting, and system optimization across battery pack and embedded systems.

Responsibilities:

• Apply advanced expertise to diagnose, resolve, and drive solutions for complex battery electrical systems engineering challenges.
• Derive and refine electrical sub‑system requirements and design guideline principles.
• Develop electrical system architecture and schematics and allocate to requirements.
• Develop external interface specifications for electrical interfaces across systems.
• Lead and effectively communicate cross‑functional electrical system engineering meetings.
• Drive resolution of electrical system issues between customers and design engineers.
• Support the Lead Systems Engineer on electrical engineering topics.
• Support Design Release Engineers during electrical component design reviews for Electromagnetic Compatibility (EMC) robustness, grounding/bonding strategy, shielding, harness routing, High Voltage / Low Voltage (HV/LV) separation, connector selection, isolation, and system integration.
• Analyze electrical system failure modes in Design Failure Mode and Effects Analysis (DFMEA) and support functional safety analysis.
• Develop electrical sub‑system integration test plans and drive prototype testing and analysis for EMC, communication, HV/LV power distribution, and BMS peripheral systems (contactors, pre-charge, voltage/temperature/current/isolation sensors), etc. 
• Collaborate with Validation Engineers, design engineers, suppliers, and external test labs to resolve Power, Control, Communication, and EMC-related design and compliance issues.
• Support analysis of BMS schematics, layouts, hardware, controls, communications, and Worst‑Case Circuit Analysis (WCCA).
• Track and prioritize top technical risks and known electrical system issues.
• Troubleshoot battery pack issues and update requirements and engineering guidelines from lessons learned.
• Drive model‑based analysis of the electrical battery system with Computer-Aided Design (CAD), Simulation Program with Integrated Circuit Emphasis (SPICE), and Computer-Aided Engineering (CAE).
• Support Validation with planning, testing, root-cause analysis, and corrective actions.
• Support electrical inspection requirements for end‑of‑line testing.
• Adhere to federal and state regulations.
• Adhere to all company policies, processes, and procedures.
• Perform other duties as assigned.
• Maintain predictable and reliable attendance.

Position Qualifications:

• Bachelor’s degree in Electrical Engineering, or an equivalent field.
• Master’s degree preferred.
• Minimum of seven (7) years of experience in automotive or similar electrical systems including HV/LV Battery Systems, BMS, Battery Disconnect Units (BDU), Power Distribution Units (PDU), or Controller Area Network (CAN) communications.
• Experience with DFMEA, Process Failure Mode and Effects Analysis (PFMEA), Design Verification Plan and Report (DVP&R), and the product design life cycle.
• Experience working in a lab environment working with multimeters, oscilloscopes, HiPot testers, Inductance-Capacitance-Resistance (LCR) meters, Controller Area Network analysis tools (CANalyzer/CANoe), and Data Acquisition systems (DAQs).
• Experience with WCCA, SPICE, CAD/CAE, and electrical design tools.
• Preferred experience with Ansys, Mathcad, MATLAB, Simulink, Simscape, LTspice, and Altium.
• Preferred experience with requirements management tools and systems engineering methodologies including Jama, DOORS, Sparx Enterprise Architect, Model Based Systems Engineering (MBSE), and SysML.
• Preferred experience with AI (Copilot, ChatGPT, Claude).
• Preferred experience handling high‑voltage lithium‑ion battery systems.

Key Competencies:

• Focuses on Quality: Drives work results with quality focus in actions and results.
• Continual Improvement: Displays a consistent orientation toward producing the highest quality products or services, while keeping a focus on sustainability. Constantly looking for incremental improvements in work and processes and results.
• Decision Making & Analysis: Makes sound decisions based upon a mixture of data-driven analysis, expertise, experience and judgment; collects relevant information, seeking input from others, and identifies connections and/or root causes of problems.
• Takes Initiative: Exhibits strong drive for results and success; conveys a sense of urgency and drives issues to closure; persists despite obstacles and opposition.
• Delivers Results: Achievement-oriented, feeling a sense of urgency to reach goals on time, if not before.
• Partnership Development: Establishes productive and effective relationships with both internal and external stakeholders.
