12v System Design Engineer

The12V Systems Design Engineeris a key contributorwithinthe Product Development & Technology (PDT) organization,operatingin the Electrified Hardware Engineering (EHE) and Hardware Engineering (HWE) perimeter. The role supports the design, integration, validation, and vehicle-level performance of the12V Energy Provider subsystem.

This positionis responsible fordefining 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,componentsizing, 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, andconsolidatestakeholder inputs from vehicle systems and 12V sub-domains

• Identifyand manage environmental, operational, and architectural constraints

• Define and manageupper-level12V 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

• Performbattery sizing calculationsbased on vehicle load profiles, duty cycles, and customer usage scenarios

• Performalternator sizing and capability analysisto ensure adequate power generation under all operating conditions

• ConductIgnition 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 executesystem-level and vehicle-level validation plansfor 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 andvalidatedto achieve expected vehicle behavior

Diagnostics, Communication & Issue Management

• UseCANoeand CANalyzerto analyze CAN and LIN communication, signal behavior, and diagnostics

• Validate network behavior during key-on, key-off, and sleep transitions

• DiagnoseLIN communication issues including wake-up behavior, timeouts, and configuration issues

• UsePICO Scope and oscilloscopesto 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 andmaintaintechnical 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
