The Manufacturingorganization is seeking a solutions-oriented Vehicle Diagnostic Engineer to support the Assembly Plant Quality team. This role is focused on vehicle diagnostics in a production environment, including electrical and mechanical failure analysis, interpretation of vehicle signals, and technical root cause definition for issues identified during assembly, End-of-Line validation, certification, containment, rework and quality verification processes.

Core Mission: Diagnose, understand and resolve vehicle issues by connecting mechanical operation, electrical/electronic behavior, diagnostic data and production process conditions to define accurate root cause and sustainable corrective actions.

Key Responsibilities Lead vehicle diagnostic activities in the assembly plant for issues detected during build, End-of-Line, certification, quality gates, rework areas, yard holds and customer protection activities. Use diagnostic tools to read, monitor and interpret vehicle signals, DTCs, network communication, module behavior and system responses to support failure analysis. Analyze electrical and mechanical vehicle systems to determine true root cause, including interaction between components, wiring, modules, software behavior, assembly process and design intent. Support and lead cross-functional troubleshooting with Manufacturing, Product Engineering, Quality, Maintenance, Supplier Quality and Corporate Engineering teams. Document diagnostics, findings, evidence, containment actions, clean point definition and corrective action status in a clear, structured and data-driven manner. Support Corporate Quality objectives and internal/external KPI improvement by identifying top issues, trends, recurrence risk and effectiveness of corrective actions. Protect vehicle design intent and function by validating repair/inspection procedures,



rework methods and product disposition decisions according to engineering standards. Participate in technical calls with Corporate teams, clearly communicating failure analysis status, diagnostic strategy, evidence and support required for resolution. Support launch, pilot builds and production readiness activities by identifying diagnostic risks, validating vehicle functionality and escalating critical electrical/mechanical concerns. Provide technical guidance to salary and hourly personnel regarding diagnostic methods, inspection criteria, issue escalation and repair confirmation. Basic Qualifications Bachelor’s degree in Engineering, preferably Mechanical, Electromechanical, Electronics, Automotive Systems, Automotive Design or a closely related technical engineering discipline. Equivalent relevant experience may be considered. 5+ years of experience in the automotive industry, preferably in vehicle assembly, manufacturing, diagnostics, product quality, electrical systems, mechanical systems or root cause analysis. Strong understanding of vehicle operation from both electrical/electronic and mechanical perspectives, including the ability to connect component behavior with complete vehicle function. Hands-on experience using automotive diagnostic tools for reading signals, DTCs, module behavior, network communication and vehicle performance conditions. Advanced English communication skills, written and spoken, required for frequent interaction with Corporate Engineering, Quality and cross-functional teams.



Strong analytical capability to investigate complex issues, organize evidence, perform structured problem solving and define root cause based on facts and data. Ability to work under pressure, manage priorities, meet objectives and respond quickly to production needs in a fast-paced manufacturing environment. Self-directed, proactive and capable of working with limited supervision while maintaining accountability for deliverables and issue closure. Full availability to support any productive shift according to company needs, including first, second or third shift, overtime and weekends. Preferred Qualifications Experience with CDA, CANalyzer/DI alizer, CAN tools or equivalent diagnostic and signal interpretation tools. Experience with similar tools from other OEMs or automotive companies may be considered. Ability to interpret vehicle communication signals and correlate CAN data with physical vehicle behavior, failure modes and process conditions. Experience in electrical wiring, electronic modules, software validation, powertrain/chassis/body systems, End-of-Line testing or vehicle functional validation. Previous experience in manufacturing quality, product engineering, launch, rework/repair validation or issue resolution in a vehicle assembly plant. Proficiency with Microsoft Excel and Power Point for data analysis, technical reporting and presentation of findings to plant and management audiences. Required Competencies Technical curiosity and strong hands-on diagnostic mindset. Clear communication with plant floor teams, engineers, managers and Corporate stakeholders. High sense of urgency, ownership and follow-through until closure. Ability to separate symptoms from root cause and validate corrective action effectiveness. Comfortable working in high-intensity environments with multiple simultaneous priorities. #J-18808-Ljbffr
