Job Summary

We are seeking an experienced Automotive System Engineer with strong expertise in system architecture, system decomposition, and Model-Based Systems Engineering (MBSE) for Lithium-Ion Battery Systems, Super Capacitor modules, and Battery Management Systems (BMS).

The ideal candidate will have hands-on experience with Automotive SPICE (ASPICE) SYS.3, system architecture modeling, interface definition, and requirements allocation across hardware, software, diagnostics, functional safety, and cybersecurity domains.

This role focuses on developing scalable, reliable, and reusable system architectures for automotive energy storage products while ensuring alignment with customer requirements, engineering standards, and regulatory expectations.

Key Responsibilities

• Develop and maintain system architectural designs for Lithium-Ion batteries, Super Capacitor modules, and Battery Management Systems.
• Define system elements, subsystems, logical and physical architectures, communication networks, and operational modes.
• Decompose system architectures into battery packs, battery modules, cell monitoring units, BMS controllers, contactor systems, sensors, and thermal management components.
• Define internal and external system interfaces and develop interface control specifications.
• Allocate system requirements and functions across hardware, software, mechanical, diagnostics, functional safety, and cybersecurity domains.
• Conduct architectural trade-off studies, feasibility assessments, and technology evaluations.
• Maintain bidirectional traceability between system requirements and architectural elements.
• Analyze battery system functionality, including SOC, SOH, SOP, cell balancing, thermal management, contactor control, diagnostics, and charging/discharging management.
• Collaborate with hardware, software, mechanical, validation, functional safety, and cybersecurity engineering teams.
• Conduct architecture reviews, impact assessments, and engineering change management activities.
• Ensure compliance with ASPICE SYS.3 process expectations and maintain architecture documentation, reviews, baselines, and configuration records.
• Support system integration activities and resolve architectural inconsistencies.
• Promote architecture reuse, scalability, maintainability, and compliance with customer specifications.
• Document architectural decisions, interface models, system dependencies, and technical risks.
