À propos
The 12v Systems Design Engineer is a key contributor within the Product Development & Technology (PDT) organization, operating in the Electrified Hardware Engineering (EHE) and Hardware Engineering (HWE) perimeter. The role supports the design, integration, validation, and vehicle-level performance of the 12v Energy Provider subsystem. This position is responsible for defining robust, cost-effective, and innovative 12v electrical system solutions by ensuring alignment between vehicle needs, system and subsystem strategies, and architectural constraints. The engineer works cross-functionally on system architecture, requirements definition, component sizing, vehicle testing, diagnostics, and validation to ensure correct vehicle behavior and customer satisfaction. Hands-on experience with vehicle electrical systems, communication networks, testing tools, and data analysis is essential. Key Responsibilities:
Gather, analyze, and consolidate stakeholder inputs from vehicle systems and 12v sub-domains Identify and manage environmental, operational, and architectural constraints Define and manage upper-level 12v system requirements, constraints, and use cases Define functional system architectures aligned with Quality, Cost, Timing, and Performance (QCTP) objectives Perform functional decomposition and allocation across hardware, software, and processes Provide system-level synthesis of system behavior, operating strategies, and vehicle interactions Electrical Power System Design & Sizing
Perform battery sizing calculations based on vehicle load profiles, duty cycles, and customer usage scenarios Perform alternator sizing and capability analysis to ensure adequate power generation under all operating conditions Conduct Ignition Off Draw (IOD) and parasitic load analysis, including network and module sleep behavior Support definition and optimization of charging and power management strategies Requirements & Functional Specification
Define high-level functional and technical requirements for hardware, software, and validation teams Ensure full requirements traceability throughout the development lifecycle Ensure clear understanding, alignment, and acceptance of system requirements across stakeholders Support diagnostics and functional behavior definition related to the 12v system Vehicle-Level Testing & Validation
Define and execute system-level and vehicle-level validation plans for the 12v electrical system Plan, set up, and conduct vehicle tests covering: 12v lead-acid and future lithium battery systems Alternators and charging systems 120v / 230v DC/AC inverters Battery sensors and intelligent power components LIN- and CAN-based loads and control modules Execute testing under various environmental and operating conditions (hot, cold, key on/off, high load, charging, sleep modes) Review, approve, and document system validation and test results Ensure system strategies are correctly implemented and validated to achieve expected vehicle behavior Diagnostics, Communication & Issue Management
Use CANoe and CANalyzer to analyze CAN and LIN communication, signal behavior, and diagnostics Validate network behavior during key-on, key-off, and sleep transitions Diagnose LIN communication issues including wake-up behavior, timeouts, and configuration issues Use PICO Scope and oscilloscopes to analyze voltage, current, ripple, transients, and communication signals Perform root cause analysis of electrical, communication, and sleep current issues Track, manage, and resolve issues and deviations across the development lifecycle Cross-Functional & Supplier Collaboration
Work closely with systems, software, hardware, and validation teams to align architecture and requirements Support supplier coordination for batteries, alternators, inverters, sensors, and LIN/CAN-controlled components Participate in design reviews, technical reviews, issue resolution meetings, and program milestones Documentation & Process Compliance
Create and maintain technical documentation including system analyses, requirements, test plans, and reports Support compliance with internal development processes, system engineering methodologies, and automotive standards Contribute to continuous improvement of system engineering and validation processes Basic Requirements:
Bachelor's degree in Electrical Engineering or a related discipline A minimum of 5 years of relevant experience. Experience in system engineering, electrical architecture, or vehicle integration Hands-on experience with vehicle-level electrical testing and troubleshooting 12v electrical power systems and energy storage experience Root cause analysis and risk assessment experience Preferred Requirements:
Skills & Competencies Battery and alternator sizing Ignition Off Draw (IOD) and vehicle sleep behavior DC/DC converters, DC/AC inverters, and other power electronics CAN & LIN communication and diagnostics Functional analysis, requirements management, and validation strategy Tools & Languages CANoe, CANalyzer PICO Scope and electrical measurement equipment Vehicle data logging and test instrumentation Microsoft Office (Teams, Outlook, Excel, Visio)
