Job description

Overview

As a Lead Mechanical Engineer, you will lead the delivery of complex mechanical and piping engineering for mining and industrial projects across Canada, guiding multidisciplinary teams through all project phases to deliver safe, efficient, and high‑performing systems.

Location

This position can be located in any Canadian office with preference for Northern Ontario, BC and Atlantic locations.

Responsibilities

• Lead as a technical expert on mechanical and piping engineering packages for multidisciplinary mining and industrial projects across all phases—from conceptual studies to detailed engineering and construction support.
• Apply deep knowledge of codes and standards (ASME B31.3, B31.4, B31.8, ASME VIII Div 1/2, API, TEMA) to develop safe, compliant, and reliable mechanical and piping systems.
• Direct and review piping layouts, isometrics, bills of materials (BOMs), and fabrication deliverables, ensuring accuracy, constructability, and alignment with project standards.
• Evaluate, select, and specify rotating equipment—such as pumps, compressors, and blowers—using lifecycle cost, operability, and performance criteria to support long‑term asset reliability.
• Oversee the mechanical design of pressure vessels, heat exchangers, tanks, chutes, bins, hoppers, and conveyor system components in collaboration with structural and process engineering teams.
• Prepare and review mechanical calculations (e.g., wall thickness, branch reinforcement, external pressure analysis) to verify the integrity and performance of critical assets.
• Develop and maintain project standards, piping material specifications, valve specifications, and equipment datasheets that drive consistency and quality across projects.
• Prepare RFQs and lead technical evaluations and comparison reports for bulk materials, valves, specialty components, and rotating equipment, partnering closely with procurement.
• Resolve complex design and material issues by working collaboratively with engineering, procurement, and construction partners to keep projects on track and on budget.
• Develop inspection and test plans (ITPs), including hydrostatic testing and NDT requirements for tanks and vessels, to support quality assurance and commissioning.

Qualifications

• At least 12+ years of experience in mechanical engineering within industrial and/or mining environments in a senior capacity.
• Strong track record leading and delivering EPCM projects across heavy industrial sectors such as mining, mineral processing, with exposure to large, complex brownfield and greenfield projects.
• Hands‑on experience with the mechanical design of chutes, hoppers, bins, conveyors, and associated structural elements, and understanding of performance in harsh operating environments.
• Experience with dust collection systems, ventilation ducting, and flue gas systems desirable.
• Deep understanding of piping materials, equipment standards, fabrication processes, and construction practices to enable sound engineering and constructability decisions.
• Comfortable developing RFQs, material take‑offs (MTOs), technical bid evaluations, and comparison reports, and collaborating closely with supply chain partners.
• Thrives in LEAN or continuous‑improvement‑focused environments and brings an improvement mindset to workflows, standards, and project delivery.
• Bachelor’s degree in Mechanical Engineering (Master’s degree considered an asset).
• Registered, or eligible to register, as a Professional Engineer (P.Eng.) in Canada.
