Performance Wise is a light-duty diesel repair and maintenance shop serving customers with Ford Power Stroke, Ram/Dodge Cummins, and Chevrolet/GMC Duramax trucks and vans. We are hiring a dependable General Service Technician (GST) whose primary responsibility is routine vehicle maintenance, inspections, and supporting the service team. Diesel emissions testing is also an essential, ongoing part of this position. The person hired must be willing to complete the required emissions testing class and pass the certification examination within 30 days of hire, obtain and maintain certification, and perform emissions tests whenever business needs require, including interrupting other GST work when directed.

• Perform routine GST services such as oil and filter changes, tire rotations, brake services / maintenance, front-end work, fluid services, basic inspections, and other maintenance appropriate to training and authorization.

• Complete vehicle condition and safety checks; document findings clearly and report concerns to the shop foreman or service advisor.

• Obtain the required Colorado diesel emissions tester certification within 30 days of hire by completing the required emissions class and passing the certification examination; maintain certification throughout employment.

• Perform diesel emissions tests accurately and professionally whenever assigned or needed during the workday, even when the primary assignment is general service work; follow applicable procedures and document results.

• Maintain shop readiness: empty used-oil caddies, handle waste fluids properly, replenish washer fluid and coolant supplies, monitor bulk-fluid levels, empty trash, and clean bays and shared areas.

• Assist senior technicians with approved tasks and follow service procedures, torque specifications, quality checks, and safe tool use.

• Greet emissions customers professionally, answer basic service questions, and process testing payments when assigned.

• Follow PPE, lift, chemical-handling, environmental, and shop safety practices; accurately record work time and completed services in Tekmetric.

• Valid driver’s license and driving record acceptable for operating customer vehicles.

• Mechanical aptitude, dependable attendance, strong attention to detail, and willingness to learn.

• Ability to work safely around trucks, lifts, tools, chemicals, and moving equipment.

• Clear communication and a customer-first, team-oriented approach.

• Automotive maintenance or quick-lube experience preferred; diesel experience is a plus, not required.

• Willingness and ability to complete the required diesel emissions class and pass the certification examination within 30 days of hire, obtain and maintain certification, and perform emissions tests on demand as an essential job duty. Existing certification is a plus but is not required to apply.

Monday–Friday, typically 7:45 a.m.–4:15 p.m., including a 30-minute unpaid meal break (approximately 40 paid hours weekly). Hourly, non-exempt position; overtime paid as required by law. On-site at 4395 Xenon St., Wheat Ridge, CO 80033.
