About Us

Since the mid-1970’s companies of all sizes have trusted Commercial Truck & Mobile Repair to maintain their fleets. Commercial Truck & Mobile Repair is a full-service Fleet Maintenance Management Company. Commercial Truck & Mobile Repair is part of the Berger Moving & Storage family of Companies. Berger Moving & Storage is a leading provider of relocation, distribution and warehousing services. Founded in 1910, Berger has been providing moving and storage services to individuals and businesses for over 100 years! Berger is Allied Van Lines’ largest agent with 18 locations throughout the U.S.

We are an established, growing commercial fleet maintenance provider expanding our footprint with a brand-new, state-of-the-art heavy-duty diesel repair facility on the West Side of Phoenix. Joining our successful operations in St. Paul, MN and Houston, TX, this new location is perfectly situated near major transportation hubs to service regional and national fleets. We are looking for an entrepreneurial Shop Manager to launch this branch, establish our local market presence, and build a high-performing team from the ground floor.

The Role

This position requires a unique blend of operational leadership and aggressive sales drive. While you will oversee the shop floor, technicians, and repair quality, your primary focus will be on the front counter and out in the field. You will actively leverage our multi-regional reputation to pursue new fleet accounts, convert incoming diagnostic leads into paying jobs, and maximize the profitability of every bay.

Key Responsibilities

Shop Operations: Oversee daily workflow, schedule repairs, manage work orders, and track parts inventory.

Technical Leadership: Diagnose and repair complex electrical, hydraulic, air brake, and diesel engine systems.

Team Mentorship: Train, guide, and motivate a growing team of mechanics.

Quality Control: Inspect completed repairs to ensure safety and accuracy before vehicles leave the shop.

Customer & Vendor Relations: Communicate repair timelines clearly with clients and source reliable parts vendors.

Safety & Compliance: Maintain a clean, organized, and OSHA-compliant shop environment. 

Vendor & Inventory Management: Establish relationships with local parts distributors to ensure fast delivery times and optimal pricing.

Shop Operations: Manage daily workflows, schedule technicians, track key performance indicators (KPIs), and maintain strict margin controls on parts and labor.

What You Bring

Experience: 5+ years of hands-on diesel mechanic experience, with at least 2 years in a lead, foreman, or management role.

Technical Skill: Advanced proficiency in heavy-duty diagnostics, electrical troubleshooting, and emissions/aftertreatment systems.

Certifications: ASE Heavy Truck Certifications (T1-T8) or master status preferred, but proven real-world experience takes priority.

Communication: Strong computer skills for digital work-order management and friendly communication with customers.

Driver’s License: Valid driver's license required (CDL Class A or B is a strong plus). 

What We Offer

Competitive base salary of $80,000–$95,000 + performance incentives.

Comprehensive health, dental, and vision insurance packages.

Paid time off (PTO) and paid holidays.

Ongoing technical training and certification sponsorship.

A ground-floor opportunity to build and scale a premier diesel shop.

Industry Knowledge: Deep understanding of diesel repair operations, labor times, parts sourcing, and fleet maintenance demands.

Local Market Awareness : Familiarity with the Phoenix logistics and commercial transportation landscape is highly preferred.

Technician Background (Plus): Previous hands-on mechanic experience is a strong advantage, but the ability to sell work and manage people takes priority.

Tech-Savvy: Experience working with modern digital shop management software (SMS) and CRM systems.
