Core Responsibilities

Primary Functions

Act as the primary technical liaison between central engineering teams and field service technicians to resolve complex vehicle system issues related to electronics, software, and mechanical components.
Perform in-depth root cause analysis on escalated service concerns, utilizing advanced diagnostic equipment, data logging tools, and fundamental engineering principles to identify the source of failure.
Travel frequently to customer sites, dealerships, or service centers to provide on-site, hands-on diagnostic support and troubleshooting for critical vehicle-down or high-priority situations.
Develop, validate, and publish official service bulletins, repair procedures, and diagnostic guides for use by the wider service network, ensuring clarity, accuracy, and serviceability.
Capture and meticulously document vehicle data, customer feedback, and failure modes to create comprehensive, data-driven field reports for product engineering and quality assurance teams.
Lead remote diagnostic sessions with field technicians, expertly guiding them through complex troubleshooting steps for electrical, mechanical, and software-related problems.
Validate new vehicle software releases and hardware components from a serviceability perspective, providing critical feedback to R&D on potential field issues before product launch.
Design and deliver specialized technical training programs for service technicians, focusing on new vehicle technologies, complex systems (like EV/ADAS), and advanced diagnostic strategies.
Analyze warranty claim data and field intelligence reports to identify emerging failure trends, and proactively develop containment plans and engineering countermeasures.
Collaborate directly with design and release engineers to influence future product designs for improved reliability, serviceability, and diagnostics based on real-world field data.
Manage and maintain a fleet of engineering test vehicles, ensuring they are properly equipped and configured for specific diagnostic investigations and validation tasks.
Replicate and diagnose intermittent and difficult-to-reproduce customer complaints in a controlled workshop environment or through targeted, data-logged test drives.
Interface directly with Tier 1 and Tier 2 suppliers to investigate component-level failures and drive corrective actions throughout the supply chain to prevent recurrence.
Provide expert-level technical support for complex vehicle systems including high-voltage (HV) batteries, electric drivetrains, advanced driver-assistance systems (ADAS), and connected vehicle platforms.
Utilize CAN, LIN, and Automotive Ethernet diagnostic tools like Vector CANalyzer to intercept and analyze vehicle network communications for troubleshooting complex system interactions.
Author detailed technical reports that clearly communicate findings, root cause, and recommended permanent solutions to both technical and non-technical stakeholders across the business.
Support the development and testing of new special service tools and diagnostic software, ensuring they are effective, robust, and user-friendly for technicians in the field.
Act as the subject matter expert (SME) during critical vehicle launch phases, providing real-time support and rapid problem-solving for the initial wave of field issues.
Champion a "Fix It Right the First Time" culture by providing clear, concise, and accurate repair information and diagnostic support to the entire service network.
Evaluate competitor vehicles to benchmark service procedures, diagnostic strategies, special tools, and overall vehicle construction and technology to inform internal development.
Manage the technical escalation process for high-priority cases, ensuring timely communication and resolution while minimizing vehicle downtime and customer dissatisfaction.
Participate in regular cross-functional meetings with quality, manufacturing, and engineering departments to represent the "voice of the service technician" and the "voice of the customer."

Secondary Functions

Support ad-hoc data requests and exploratory data analysis of field failure data to uncover hidden trends.
Contribute to the organization's internal knowledge base and technical documentation repository.
Collaborate with the legal and safety teams to provide technical details for product liability or recall investigations.
Mentor junior engineers and new technicians within the technical service organization, sharing expertise and best practices.
