Sr. Mechanical Engineer

The Senior Mechanical Engineer is a hands-on technical lead responsible for the mechanical engineering of modular process and water-treatment equipment packages from proposal and concept development through detailed design, fabrication, testing, and project closeout. The role requires strong skid-engineering capability across pressure vessels and other static equipment, valves, piping systems, package layout, and fabrication execution. The successful candidate will translate client requirements into safe, practical, code-compliant, and manufacturable solutions while providing technical leadership to multidisciplinary project teams, designers, suppliers, and fabrication partners

This position will be based at our Calgary Water Solutions location.

• Lead mechanical engineering for modular skids and packaged systems, including vessels, tanks, piping, supports, platforms, and equipment interfaces.
• Develop and review mechanical specifications, datasheets, design calculations, material selections, BOMs/MTOs, and technical documentation.
• Review 3D models, layouts, piping isometrics, fabrication drawings, and equipment designs for constructability, operability, maintainability, and transportation requirements.
• Ensure designs comply with applicable codes, standards, client specifications, and project requirements.
• Prepare technical requisitions, evaluate vendor proposals, and complete technical bid evaluations.
• Provide technical support to fabrication facilities and subcontractors, including resolving shop queries, non-conformances, and design changes.
• Participate in design reviews, shop inspections, pressure tests, FATs, hazard reviews, and lessons-learned activities.
• Coordinate with process, piping, electrical, instrumentation, structural, procurement, quality, project engineering, and project management teams.
• Deliver mechanical engineering work within project scope, schedule, budget, and quality requirements.
• Support proposals with concept development, preliminary sizing, technical clarifications, risk identification, and cost/manhour estimates.
• Establish and maintain standardized package designs and engineering practices to support efficient and cost-effective project execution.
• Provide technical leadership and communicate with clients, suppliers, inspectors, engineering partners, and internal stakeholders.

• Bachelor’s degree in Mechanical Engineering and Professional Engineer (P.Eng.) registration with APEGA, or eligibility to obtain APEGA registration upon joining.
• 12+ years of progressive mechanical engineering experience in EPC, packaged equipment, fabrication, or detailed engineering environments, including proposal support, cost optimization, standardization, and product/package development.
• Demonstrated experience in the design and integration of pressure vessels, static equipment, valves, piping systems, and modular skid packages, with strong fabrication and shop-support expertise.
• Working knowledge of applicable pressure equipment and piping codes, standards, and client specifications, with experience in produced water treatment, oil-water separation, filtration, hydrocyclones, flotation, pumping, or similar process-treatment systems.
• Hands-on experience with mechanical design and analysis tools such as COMPRESS, PV Elite, and CAESAR II, including preparation and review of engineering calculations and technical documentation.
• Proficiency in 3D plant design and CAD systems, including AutoCAD, CADWorx, or similar platforms, with the ability to review and develop engineering and fabrication deliverables.
• Strong knowledge of materials, welding, corrosion control, coatings, insulation, inspection, testing, pressure-equipment documentation, Canadian…
