You will lead technically complex projects across multiple sectors (commercial, institutional, and industrial) and provide hands-on design expertise when junior and intermediate engineers may lack experience.

In this role, you will also mentor and guide the mechanical design team, ensuring high-quality designs, Revit/CAD model accuracy, code compliance, and integrated system coordination. You will serve as the technical lead and a key contributor to both design solutions and project execution.

  • Develop and review Revit and AutoCAD models, detailed drawings, specifications, and calculations
  • Solve complex technical challenges where junior engineers require guidance

Team Mentorship & Technical Oversight

  • Provide technical leadership and mentorship to junior and intermediate engineers
  • Review and approve design packages and calculations, ensuring compliance with industry standards
  • Establish design review milestones and best practices to maintain high-quality deliverables

Project Collaboration & Construction Support

  • Coordinate design with architectural, structural, electrical, and other disciplines
  • Participate in technical coordination meetings, RFI responses, and shop drawing reviews
  • Support construction administration and site inspections as required

Continuous Improvement & Innovation

  • Contribute to the development and improvement of internal standards, workflows, and design tools
  • Stay current on emerging technologies, energy-efficient design, and industry best practices
  • Identify opportunities for innovation in design, project delivery, and client service

Qualifications & Skills:

  • Degree in Mechanical Engineering or Mechanical Engineering Technology
  • P.Eng designation (or eligibility) preferred
  • Minimum 10+ years of progressive experience in mechanical systems design
  • 3+ years of experience managing mechanical design projects, including oversight of day-to-day operations, team coordination, and resource planning
  • 3+ years of experience leading a team, providing guidance, mentorship, and performance oversight
  • Proven experience with HVAC, plumbing, drainage, and fire protection system design across multiple sectors
  • Strong hands-on Revit and AutoCAD proficiency
  • Solid understanding of OBC, ASHRAE, NFPA, and other applicable codes and standards
  • Experience leading complex projects, managing design deliverables, and mentoring junior and intermediate staff
  • Strong analytical, problem-solving, and decision-making skills

  • A practical, solutions-driven approach to engineering
  • Strong long-term client relationships built on trust, quality, and reliability
  • A collaborative environment where engineers, designers, and project managers work closely to turn concepts into fully realized building systems
