Excavating has been doing heavy civil work in the Waterloo Region and beyond for four generations. Earthwork, concrete, pipe installation, demolitions, aggregates — we run a serious fleet of iron, and we need the person who keeps it moving. A field service diesel technician who goes where the work is.

You'll be the technical backbone of our fleet operations — working independently in the field and alongside our shop. You'll carry a service truck, diagnostic tools, and the kind of judgement that comes from doing this for real. Diagnose and repair diesel engines, hydraulic systems, electrical systems, powertrains, and air brake systems on heavy construction equipment and commercial transport vehicles.

Perform planned and unplanned field service calls — on site, on time, with minimal supervision. Execute preventive maintenance schedules that keep equipment uptime high and warranty claims clean. Operate advanced diagnostic software and electronic troubleshooting tools across multiple equipment lines.

Complete work orders, service records, and documentation accurately — we run a tight shop and the paper trail matters. Identify parts requirements, manage your vehicle inventory, and flag issues before they become failures.



Support equipment compliance with OHSA and Ministry of Labour inspection standards.

Collaborate with operators, project managers, and estimators — your read on machine health shapes project planning. 310T (Truck and Coach Technician), 421A (Heavy Duty Equipment Technician), or Red Seal certification — licensed or actively completing apprenticeship. ~ Solid working knowledge of diesel engines, hydraulic systems, electrical/electronic systems, and air brake systems. ~ Experience with diagnostic software. ~ Ability to work independently in the field — you're organized, you communicate, you manage your time without someone looking over your shoulder. ~ Comfortable reading schematics, wiring diagrams, and service manuals. ~ Genuine safety mindset — you follow lockout/tagout, you do pre‑use inspections, and you don't take shortcuts around moving equipment.
