An established and growing MEP consulting engineering firm is seeking a Junior Mechanical Engineer to join its team and contribute to the design of HVAC and plumbing systems for commercial, healthcare, institutional, and laboratory projects.

This is an excellent opportunity for a recent Mechanical Engineering graduate with relevant internship or co-op experience, or an early-career engineer with up to three years of professional experience, to build a career in MEP consulting.

You'll work alongside experienced engineers, gain practical exposure to building systems design, and develop your technical skills through real-world projects, mentorship, and professional development.

Candidates should have either relevant internship/co-op experience or approximately 6 months to 3 years of relevant full-time professional experience in MEP engineering, HVAC design, plumbing design, or building systems.

Responsibilities

  • Assist with the design and engineering of HVAC and/or plumbing systems for commercial buildings.
  • Develop engineering layouts, drawings, and construction documents using Revit and AutoCAD.
  • Support HVAC load calculations, equipment selection, ductwork layouts, and piping design.
  • 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.

Qualifications

  • Bachelor's degree in Mechanical Engineering required.
  • 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.
  • Willingness to learn, take direction, and grow within a collaborative engineering environment.

Why Consider This Opportunity?

  • Work alongside experienced engineers and learn industry best practices.
  • Gain practical experience with a variety of commercial building projects.
  • Develop your Revit, HVAC, plumbing, and building systems design skills.
  • Build a foundation for long-term career growth in MEP consulting engineering.
