ABOUT THE ROLE

F5 Global Talent is hiring an experienced Residential HVAC Design Engineer to handle pre-design HVAC engineering and energy-code compliance for U.S. residential projects.

About 60% of the role is HVAC mechanical design: performing ACCA Manual J heating and cooling load calculations, sizing and selecting equipment, and designing residential HVAC systems.

The other 40% focuses on the building envelope — insulation, walls, roofs, floors, windows, glazing, and doors — and making sure the project meets applicable energy codes using REScheck and COMcheck.

This is hands-on pre-design engineering, not post-design energy modeling. We need someone who has personally performed the load calculations, selected the equipment, and specified the building envelope.

This is a full-time, remote role for candidates based in India, with flexible hours overlapping U.S. client hours.

IMPORTANT

If your background is primarily EnergyPlus, eQUEST, or similar energy simulation performed after someone else designed the building, this role is probably not the right fit.

We are looking for someone who can actually design the HVAC system and make the envelope decisions themselves.

WHAT YOU’LL DO

- Perform ACCA Manual J heating and cooling load calculations
- Size and recommend HVAC equipment for residential projects
- Design residential HVAC systems before construction begins
- Evaluate building layouts for thermal comfort and energy efficiency
- Specify insulation requirements for walls, roofs, and floors
- Evaluate windows, glazing, doors, and other envelope components
- Select appropriate building-envelope materials




- Prepare REScheck and COMcheck energy-code compliance
- Review architectural drawings and construction details
- Prepare load-calculation reports, compliance reports, and technical documentation
- Coordinate with architects, engineers, and project teams to resolve design questions

WHAT WE’RE LOOKING FOR

- 3+ years of hands-on residential HVAC design and building-envelope experience
- Strong ACCA Manual J experience
- Residential heating and cooling load-calculation experience
- HVAC equipment sizing and selection experience
- Experience designing residential HVAC systems
- REScheck and/or COMcheck experience
- Understanding of residential building-envelope design
- Knowledge of insulation, windows, glazing, walls, roofs, and thermal performance
- Knowledge of U.S. residential energy codes and standards
- Ability to read architectural drawings and building plans
- Solid technical documentation and reporting skills
- Clear written English
- Ability to work independently in a remote workplace

NICE TO HAVE

- Bachelor’s degree in Mechanical Engineering or a related discipline
- Experience specifically with U.S. residential projects
- AutoCAD or Revit experience
- Experience preparing formal HVAC load and energy-compliance reports
- Knowledge of HVAC manufacturer equipment-selection tools and specifications
