Core Responsibilities

Primary Functions

Perform rapid, high-quality diagnostics and root-cause analysis on internal combustion engines, diesel powerplants, transmissions, and drive-train assemblies using both electronic scan tools and mechanical inspection techniques to achieve high first-time-fix rates.
Execute time-sensitive preventive maintenance and express repair services (oil changes, fluid top-offs, belt and hose replacement, filter changes, brake inspections) while documenting all actions to meet warranty, regulatory, and company service standards.
Troubleshoot and repair hydraulic systems including pumps, valves, cylinders, hoses, and fittings; perform pressure tests, leak isolation, and component replacements to restore safe operation and prevent repeat failures.
Diagnose and repair pneumatic systems and air-management components (compressors, dryers, valves, air lines) to resolve control issues and ensure reliable braking and ancillary pneumatic functions.
Inspect, diagnose, and replace brake systems (disc and drum), wheel bearings, ABS sensors, and associated brake hydraulics/electronics to meet both safety standards and customer expectations for stopping performance.
Repair and adjust steering and suspension components, including tie-rods, ball joints, shock absorbers, bushings, and alignment-related hardware, to correct drivability complaints and reduce tire wear.
Perform electrical and electronic system diagnostics, including battery/charging systems, starter circuits, lighting, instrument clusters, sensors, and ECM/TCM fault code analysis using multi-meters and OEM diagnostic software.
Conduct engine-level repairs such as head gasket replacement, valve adjustments, injector replacements, turbocharger inspections, and fuel system repairs with adherence to torque sequences and service bulletins.
Use computerized diagnostic tools and service information systems to read fault codes, access technical service bulletins (TSBs), and apply manufacturer troubleshooting flows to reduce diagnostic time.
Carry out component-level rebuilds and replacements (alternators, starters, water pumps, fuel pumps) and perform post-repair testing to verify restoration of full functionality.
Execute welding, fabrication, and minor machining tasks (MIG/TIG welding, bracket fabrication, pipe fitting) required for express repairs that cannot wait for external shop fabrication.
Maintain accurate electronic job records, time tracking, and parts usage reports in the shop management system to support billing accuracy and inventory control.
Manage parts selection, kitting, and staging for rapid turnaround jobs; coordinate with parts and procurement to reduce delays and minimize duplicate orders.
Apply standardized work processes and lean service principles (5S, takt time awareness) to increase throughput and reduce non-value-added activity in the express workflow.
Monitor and perform routine calibration and maintenance of diagnostic tools, torque tools, hoists, and shop equipment to ensure safety and measurement accuracy.
Enforce safety, environmental, and regulatory compliance (OSHA, EPA, DOT where applicable) by following safe lifting practices, lockout/tagout, hazardous waste disposal, and proper handling of fuels and lubricants.
Conduct quality assurance checks on completed jobs, including road tests and functional tests, and document corrective actions when defects are found to protect customer satisfaction and warranty claims.
Coach and mentor apprentice technicians and cross-train colleagues on express-shop best practices, diagnostic techniques, and manufacturer-recommended repair procedures.
Communicate directly with customers and dispatchers to provide clear status updates, estimate explanations, and recommended preventive maintenance to optimize fleet uptime and build trust.
Participate in after-hours on-call rotations or emergency field repairs when required, responding safely and promptly to minimize customer downtime.
Analyze recurring failures and collaborate with engineering or quality teams to recommend design or process improvements that reduce mean time between failures (MTBF).
Keep current with new technology and product changes (hybrid systems, advanced driver assistance systems, emission controls) by attending manufacturer technical training and certification programs.

Secondary Functions

Support the shop’s continuous improvement initiatives by suggesting workflow optimizations, layout changes, and tool investments that increase express throughput.
Assist parts and logistics teams in inventory reconciliation and fast-moving parts forecasting based on repair trends and seasonal demand.
Complete administrative tasks such as warranty claim submissions, parts return authorizations, and detailed job notes to maintain good vendor relations and accurate cost recovery.
Participate in daily shop huddles, service planning meetings, and post-job reviews to align priorities and communicate repair challenges or resource needs.
Provide input into technician performance reviews by tracking quality, productivity, and adherence to safe work practices.
Help prepare equipment and areas for scheduled inspections and audits by maintaining cleanliness, labeling, and accessible service records.
Support ad-hoc training sessions for new tools, new-model platforms, or updated diagnostic procedures.
