12v System Design Engineer

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 & ArchitectureGather, analyze, and consolidate stakeholder inputs from vehicle systems and 12V sub-domainsIdentify and manage environmental, operational, and architectural constraintsDefine and manage upper-level 12V system requirements, constraints, and use casesDefine functional system architectures aligned with Quality, Cost, Timing, and Performance (QCTP) objectivesPerform functional decomposition and allocation across hardware, software, and processesProvide system-level synthesis of system behavior, operating strategies, and vehicle interactions Electrical Power System Design & SizingPerform battery sizing calculations based on vehicle load profiles, duty cycles, and customer usage scenariosPerform alternator sizing and capability analysis to ensure adequate power generation under all operating conditionsConduct Ignition Off Draw (IOD) and parasitic load analysis, including network and module sleep behaviorSupport definition and optimization of charging and power management strategies Requirements & Functional SpecificationDefine high-level functional and technical requirements for hardware, software, and validation teamsEnsure full requirements traceability throughout the development lifecycleEnsure clear understanding, alignment, and acceptance of system requirements across stakeholdersSupport diagnostics and functional behavior definition related to the 12V system Vehicle-Level Testing & ValidationDefine and execute system-level and vehicle-level validation plans for the 12V electrical systemPlan, set up, and conduct vehicle tests covering:12V lead-acid and future lithium battery systemsAlternators and charging systems120V / 230V DC/AC invertersBattery sensors and intelligent power componentsLIN- and CAN-based loads and control modulesExecute 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 resultsEnsure system strategies are correctly implemented and validated to achieve expected vehicle behavior Diagnostics, Communication & Issue ManagementUse CANoe and CANalyzer to analyze CAN and LIN communication, signal behavior, and diagnosticsValidate network behavior during key-on, key-off, and sleep transitionsDiagnose LIN communication issues including wake-up behavior, timeouts, and configuration issuesUse PICO Scope and oscilloscopes to analyze voltage, current, ripple, transients, and communication signalsPerform root cause analysis of electrical, communication, and sleep current issuesTrack, manage, and resolve issues and deviations across the development lifecycle Cross-Functional & Supplier CollaborationWork closely with systems, software, hardware, and validation teams to align architecture and requirementsSupport supplier coordination for batteries, alternators, inverters, sensors, and LIN/CAN-controlled componentsParticipate in design reviews, technical reviews, issue resolution meetings, and program milestones Documentation & Process ComplianceCreate and maintain technical documentation including system analyses, requirements, test plans, and reportsSupport compliance with internal development processes, system engineering methodologies, and automotive standardsContribute to continuous improvement of system engineering and validation processes
