Über

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:

System Engineering & Architecture

  • 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
