  •  Design HVAC systems for commercial, mixed-use, and institutional projects
  •  Perform heating and cooling load calculations and ventilation analysis
  •  Design ductwork, piping, and hydronic systems
  •  Coordinate equipment selection and system layouts
  •  Coordinate with electrical, plumbing, architectural, and structural teams
  •  Lead or participate in coordination meetings and resolve design conflicts
  •  Respond to plan check comments and construction administration (CA) issues
  •  Review work for quality and mentor junior designers as needed 
     
What Success Looks Like (First 90 Days):
  •  Producing complete and accurate mechanical design packages with minimal revisions
  •  Effectively coordinating with other disciplines and resolving issues proactively
  •  Demonstrating reliability in deadlines, communication, and design quality
  •  Contributing to overall team efficiency and project delivery 
    
Non-Negotiable Requirements:
  • 4–6+ years of MEP mechanical (HVAC) design experience
  • Strong experience with U.S.-based commercial projects
  • Proficiency in Revit and mechanical design tools
  • Experience performing HVAC load calculations and system sizing
  • Working knowledge of mechanical codes and California requirements
  • Ability to work on-site in San Diego or relocate prior to start
    
Preferred Qualifications:
  • Experience with duct and hydronic system design
  • Familiarity with Title 24 and California energy compliance requirements
  • Experience leading coordination meetings
  • Ability to mentor junior designers and review work for quality
  • Strong communication sk
    
Compensation & Benefits:
At 120 Degreez, we invest in our team’s long-term success—professionally and personally.

  • 401(k) with up to 3% employer match
  • 70% employer-paid medical insurance + 100% dental and vision
  • $1,500 annual professional development and certification allowance
  • Paid Company Holidays + 2 weeks of Paid Time Off (PTO) + 1 week Paid Sick Leave
  • 100% employer-paid life insurance
  • Clear career advancement pathway from Designer through Principal
  • Collaborative, structured, and growth-focused work environment
 
Work Authorization:
We are not able to provide visa sponsorship for this role. Candidates must be authorized to work in the United States without current or future sponsorship requirements.
 
Who Should NOT Apply:
  •  Candidates with less than 4 years of relevant MEP experience
  •  Candidates without U.S.-based project experience
  •  Candidates not proficient in Revit
  •  Candidates without HVAC design experience (load calculations, duct/piping systems)
  •  Individuals seeking heavily supervised or entry-level roles
