Core Responsibilities

Primary Functions

Develop, implement, and meticulously manage preventative and predictive maintenance schedules for the entire vehicle fleet to minimize unplanned downtime and extend asset life.
Conduct comprehensive and advanced diagnostic evaluations on complex vehicle systems, including electronic control units (ECUs), powertrain, HVAC, and chassis, using specialized software and equipment to pinpoint root causes.
Engineer and document standardized repair procedures for common and complex faults, ensuring consistency, quality, and safety across all maintenance activities.
Act as the highest level of technical support for maintenance technicians, providing expert guidance, hands-on assistance, and mentorship for challenging diagnostic and repair tasks.
Manage the entire lifecycle of vehicle assets, from specification and acquisition support to mid-life refurbishment recommendations and end-of-life disposal planning.
Analyze vehicle performance data, maintenance records, and failure trends to identify recurring issues and opportunities for engineering improvements or process changes.
Liaise with vehicle and component manufacturers (OEMs) to address warranty claims, resolve engineering-level problems, and stay informed on technical service bulletins and recalls.
Oversee the vehicle parts inventory strategy, including setting stock levels for critical components, identifying reliable suppliers, and evaluating the quality of aftermarket parts.
Ensure the workshop and all maintenance practices strictly adhere to federal, state, and local safety regulations, including OSHA and environmental standards.
Lead the investigation of significant vehicle failures or incidents, performing detailed root cause analysis (RCA) to prevent future occurrences.
Design and sometimes fabricate custom tools, brackets, or modifications needed to improve vehicle reliability, serviceability, or to support specialized operational needs.
Evaluate and recommend new maintenance technologies, diagnostic tools, and workshop equipment to enhance the efficiency and capability of the maintenance team.
Create and maintain comprehensive technical documentation, including vehicle specifications, detailed repair logs, maintenance histories, and standard operating procedures (SOPs).
Manage relationships with third-party vendors and specialized repair shops, overseeing the quality and cost-effectiveness of outsourced work.
Develop and deliver technical training programs for maintenance staff on new vehicle systems, diagnostic techniques, and evolving automotive technologies (e.g., EV, ADAS).

Secondary Functions

Support ad-hoc data requests and provide exploratory analysis on fleet performance, fuel efficiency, and maintenance cost metrics.
Contribute to the organization's long-term fleet strategy and capital expenditure roadmap by providing data-driven insights on vehicle replacement cycles.
Collaborate with operational business units to translate their needs and challenges into actionable engineering requirements for vehicle specifications or modifications.
Participate in sprint planning and agile ceremonies if the maintenance team operates within such a framework, helping to prioritize technical tasks and improvement projects.
Champion a culture of safety and continuous improvement within the maintenance department, leading by example and promoting best practices.
Assist in the development of annual maintenance budgets by providing accurate forecasts for parts, labor, and external service costs.
Review and interpret complex electrical schematics, hydraulic diagrams, and mechanical blueprints to aid in troubleshooting and repairs.
