• Fit, tack, and weld structural and miscellaneous metal components with precision and adherence to tolerances.
• Operate fabrication equipment including cutting torches, plasma cutters, ironworkers, drill presses, and grinders.
• Conduct quality checks to ensure weld integrity, dimensional accuracy, and compliance with shop standards.
• Maintain a clean, organized, and safe shop environment.

Structural Steel & Miscellaneous Metals Installation (Field Work)

• Install structural steel beams, columns, joists, stairs, railings, platforms, and miscellaneous metal components on construction sites.
• Perform rigging, hoisting, and material handling using cranes, lifts, and rigging hardware.
• Align, bolt-up, weld, and secure structural components according to engineered drawings and site specifications.
• Collaborate with site supervisors, general contractors, and other trades to coordinate installation sequencing.
• Conduct field measurements, adjustments, and modifications as required.
• Follow all site safety protocols, including fall protection, lockout/tagout, and equipment operation procedures.

Industrial Mechanical Millwrighting

• Install, maintain, troubleshoot, and repair industrial machinery, mechanical systems, and production equipment.
• Perform precision alignment of motors, pumps, conveyors, gearboxes, and rotating equipment using dial indicators or laser alignment tools.
• Diagnose mechanical failures and perform corrective repairs, part replacements, and system adjustments.
• Assemble and install mechanical components such as bearings, shafts, couplings, belts, and hydraulic/pneumatic systems.
• Conduct preventive maintenance tasks to reduce downtime and extend equipment life.
• Support shutdowns, equipment upgrades, and plant modifications as required.

Requirements

• Strong proficiency in welding (MIG/TIG/SMAW) and metal fabrication techniques.
• Ability to read and interpret blueprints, fabrication drawings, and mechanical schematics.
• Skilled in rigging, hoisting, and safe material handling.
• Solid understanding of structural steel installation practices, including bolting, welding, and alignment.
• Mechanical aptitude with experience in industrial equipment installation, troubleshooting, and repair.
• Competence with precision measurement tools (tape measures, squares, micrometers, dial indicators, laser alignment).
• Strong problem-solving skills and ability to adapt to changing site conditions.
• Physical capability to lift heavy materials, work at heights, and perform physically demanding tasks.
• Commitment to safety, quality workmanship, and teamwork.

Qualifications

• Certification as a Welder (e.g., CWB) or equivalent experience.
• Relevant industrial mechanical experience considered an asset.
• Experience in structural steel installation or ironworking preferred.
• Valid driver’s licence and the ability to travel to job sites.
• Working at Heights, WHMIS, and other safety certifications (or able to obtain).

Working Conditions

• Combination of shop-based fabrication and field installation on construction or industrial sites.
• Exposure to noise, heights, confined spaces, and varying weather conditions.
• Use of PPE including welding gear, fall protection, and safety equipment.
• Occasional overtime, shift work, or weekend work depending on project demands.
