Full job description

Auger Boring Machine Operator Marathon Underground Constructors Corporation Locations: Ontario, Manitoba, Saskatchewan, Alberta, British Columbia (project-based travel required)

Marathon Underground is one of Canada’s leading specialty underground construction contractors. With more than 40 years of experience, we deliver complex trenchless solutions—including auger boring, pipe jacking, microtunnelling, horizontal directional drilling, and specialty rock tunnels—across the country. We are a fully unionized, self-performing contractor that prioritizes safety, quality, and innovation on every project.

We are seeking experienced Auger Boring Machine Operators to join our crews working on pipeline and utility installation projects throughout Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia

Key Responsibilities

Safely operate auger boring machines (ABMs) to install steel casing for underground utility crossings (gas, water, sewer, electrical, and fibre).
Set up and prepare launch/reception pits, including proper shoring and trench protection.
Install and remove auger flighting and cutting heads; monitor jacking pressure, rotation, alignment, and grade.
Read and interpret construction drawings, bore profiles, and specifications to maintain line and grade.
Coordinate with crew members (welders, labourers, and supervisors) to complete installations efficiently and safely.
Perform daily equipment inspections, basic maintenance, and report issues promptly.
Follow all company and regulatory safety procedures, including confined-space, trench safety, and ground-disturbance protocols.
Maintain accurate daily reports and participate in toolbox talks and safety meetings.
Travel to and work on project sites across Manitoba, Saskatchewan, Alberta, British Columbia, and Ontario as required.

Qualifications & Requirements

Proven experience operating auger boring / jack-and-bore equipment (preferably American Augers, Barbco, or similar machines).
Strong knowledge of steel casing installation and trenchless construction methods.
Ability to read construction plans, bore profiles, and utility maps.
Valid driver’s licence with a clean driving record (Class 1 / CDL with air brakes preferred).
Comfortable working outdoors in varying weather conditions and in excavated pits.
Physically capable of the demands of the role (lifting, climbing, working in confined spaces, etc.).
Willingness to travel extensively and work overtime, including nights or weekends when project schedules require.
Commitment to safety and a strong safety record.

Preferred assets

Welding experience or certification.
Experience with line-and-grade systems / piloting systems.
Trench safety, confined-space, or ground-disturbance certifications.
Previous experience on Canadian pipeline or utility projects.

What We Offer

Competitive union wages and benefits.
Opportunity to work with a well-established, Canada-wide contractor on challenging trenchless projects.
Steady work across multiple provinces with a company that invests in its people and equipment.
A strong safety culture and professional crew environment.
