Mechanical Engineer or Mechanical Designer (Remote)

We are seeking a talented Mechanical Engineer or Mechanical Designer to join a growing U.S.-based engineering team supporting commercial, multifamily, mixed-use, hospitality, education, and other building projects.

This is an excellent opportunity for a professional who enjoys combining HVAC system design, technical documentation, Revit-based modeling, and multidisciplinary coordination. Candidates with direct experience working on California projects will be especially valued due to the state’s specific building codes and energy-efficiency requirements.

This is a full-time, remote position supporting U.S.-based project teams during overlapping U.S. business hours.

Responsibilities

• Design HVAC and mechanical systems for commercial and multifamily buildings.
• Develop air distribution systems, ductwork, mechanical piping, hydronic systems, and exhaust systems.
• Perform HVAC load calculations, equipment sizing, and system selection.
• Prepare construction documents, plans, schedules, details, and permit packages.
• Model and coordinate mechanical systems using Revit.
• Produce and update drawings in AutoCAD or AutoCAD MEP.
• Coordinate with architectural, structural, electrical, and plumbing disciplines.
• Participate in BIM coordination, clash detection, QA/QC, and design reviews.
• Apply U.S. mechanical, building, and energy codes to project documentation.
• Collaborate with project managers, engineers, architects, contractors, and other stakeholders.

Requirements

• At least 4 years of experience in HVAC or mechanical building design.
• Experience with commercial and multifamily projects.
• Previous experience working on California projects is highly important.
• Knowledge of California building codes and energy-efficiency requirements.
• Experience with Title 24 or the California Energy Code is strongly preferred.
• Advanced proficiency in Revit and AutoCAD or AutoCAD MEP.
• Experience with HVAC load calculations, ductwork, equipment selection, and mechanical systems design.
• Previous experience working on U.S. projects and applying U.S. codes.
• Strong English communication skills.
• Ability to work independently and collaborate effectively with remote U.S.-based teams.

Preferred Qualifications

• Experience with EnergyPro.
• Experience preparing or supporting Title 24 compliance documentation.
• Familiarity with HAP, TRACE 3D Plus, or similar HVAC analysis software.
• Experience with chilled-water, heating-water, hydronic, controls, or energy-modeling projects.
• Experience supporting permit submissions and responding to plan-check comments.
• Experience with BIM coordination and clash detection.
