The Opportunity

Command Asset Readiness for a Leading Heavy Highway Contractor. Baseline Contracting, Inc. is seeking a high-caliber Heavy Equipment & Fleet Diesel Mechanic to join our elite Equipment & Fleet Maintenance team in Coplay. As a trusted leader in heavy highway construction, our complex bridge, turnpike, and PennDOT projects depend entirely on the uptime, safety, and reliability of our iron. This position is designed for an autonomous diagnostic expert who takes pride in keeping complex machinery running at peak performance. You will hold real-time command over mechanical overhauls, advanced hydraulic troubleshooting, and precision preventative maintenance. If you are a self-driven troubleshooter looking for year-round stability, a tool-supportive shop environment, and access to premium prevailing wage contracts, Baseline Contracting provides the ideal platform to build a career-long legacy.

What You Will Be Doing

• Advanced Diagnostics & Overhauls: Inspect, troubleshoot, and repair heavy-duty diesel engines, complex hydraulic arrays, and structural mechanical components.
• Component System Repair: Execute surgical removals and replacements of complete engines, heavy-duty transmissions, complex air and hydraulic braking systems, steering linkages, and suspension assemblies.
• Electrical System Troubleshooting: Isolate and resolve complex electrical faults, including starters, alternators, tracking down wiring shorts, lighting arrays, and electronic control modules.
• Lifecycle Maintenance Control: Implement comprehensive preventative maintenance programs to maximize asset reliability and minimize expensive field downtime.
• Welding & Custom Fabrication: Utilize torch-cutting and welding equipment to fabricate custom components, reinforcing brackets, and structural modifications as needed for equipment optimization.
• Operational Synchronization: Coordinate directly with field superintendents to prioritize workflow repairs, while maintaining precise digital service records and compliance documentation.
• Shop Stewardship: Maintain a lean, clean, and highly organized shop environment while actively contributing to our corporate safety-first work culture.

What You Need To Succeed (Qualifications)

• Technical Tenure: 3+ years of professional experience working directly on heavy-duty commercial trucks or heavy diesel-powered construction equipment is preferred.
• System Fluency: Comprehensive, functional knowledge of complex diesel engines, high-pressure hydraulic circuits, and heavy powertrain tracking.
• Technical Literacy: Advanced capability to read, interpret, and cross-reference industrial service manuals, wiring schematics, and digital diagnostic data.
• Physical Stamina: Physically capable of lifting and maneuvering heavy powertrain components, while working comfortably in both an active shop and outdoor field service environments.
• Licensure: A valid Driver’s License is strictly required.
• Assets: Possession of technical trade certifications, formal manufacturer training, or welding experience is a significant advantage.
• Market Traction: Mechanics possessing cross-functional capabilities across both heavy civil yellow iron (excavators, pavers, automated slipform concrete machinery) and vocational transport trucks (Class 8) are in the top 5th percentile of demand in Eastern Pennsylvania, driving excellent long-term career stability.

Compensation & Premium Benefits

• Top-Tier Earnings: Highly competitive pay of $30.00 – $45.00 per hour strictly based on your experience and equipment scope.
• Enhanced Earning Potential: Direct access to high-yield Prevailing Wage projects that offer significantly elevated hourly compensation rates.

• Health & Security: Comprehensive Medical, Dental, Vision, and Life Insurance structures.
• Future Wealth: Corporate Retirement Savings Program to support your long-term financial goals.
