  • Assist with BIM coordination, model reviews, and clash detection.
  • Coordinate mechanical designs with architectural, structural, electrical, and other project disciplines.
  • Participate in field surveys and construction site visits to gain practical project experience.
  • Help prepare design documentation and support projects through the construction document phase.
  • Collaborate with senior engineers and project teams to develop efficient, code-compliant building systems.

Requirements & Tech Stack

  • Bachelor's degree in Mechanical Engineering.
  • Relevant MEP, HVAC, plumbing, or building systems experience through an internship, co-op, or approximately 6 months to 3 years of full-time professional employment.
  • Revit experience strongly preferred; AutoCAD familiarity is beneficial.
  • Exposure to HVAC and/or plumbing design, engineering calculations, building systems, or construction drawings.
  • FE/EIT certification or progress toward taking the FE exam is a plus.
  • Strong analytical, communication, organizational, and problem-solving skills.
