Mechanical Engineer

Mechanical Engineer

Irvine, CA | Hybrid Schedule | Contract-to-Hire

Design the Systems. Own the Work. Make an Impact.

If you're tired of being the engineer who only reviews drawings, coordinates consultants, or manages projects from a distance, this opportunity is different.

We're looking for a hands-on Mechanical Engineer who wants to stay deeply involved in engineering design, calculations, Revit production, and technical problem solving. You'll work on complex healthcare, institutional, federal, and mission-critical facilities where engineering execution matters and your contributions directly impact project success.

This is an opportunity to join a growing team with a strong backlog of awarded work and immediate project needs.

What You'll Do

• Design HVAC and plumbing systems for complex facility projects
• Prepare and develop mechanical construction documents in Revit
• Perform load calculations, equipment sizing, pump calculations, and related engineering analysis
• Coordinate directly with architects, electrical engineers, structural engineers, and other design disciplines
• Support multiple active projects simultaneously
• Participate in occasional site visits and field verification activities
• Contribute immediately to project execution with limited ramp-up time

This is a production-focused position requiring direct design ownership. You'll be expected to personally perform the engineering work, not simply oversee it.

What Makes Someone Successful Here

The strongest engineers in this environment:

• Personally design HVAC and plumbing systems
• Own calculations and engineering decisions
• Produce construction documents in Revit
• Work independently with minimal supervision
• Collaborate effectively across disciplines
• Understand both design intent and real-world constructability
• Take initiative and solve problems without waiting for direction

Required Qualifications

• Hands-on HVAC design experience
• Hands-on plumbing design experience
• Revit MEP production experience
• Experience creating construction documents
• Mechanical calculation experience including load calculations and equipment sizing
• Ability to explain systems, calculations, and deliverables you personally designed
• U.S. Citizenship (required for project access)

Preferred Qualifications

• PE or EIT certification
• Federal, military, healthcare, institutional, or public-sector project experience
• Mechanical controls experience
• Building automation systems exposure
• Sequences of operation experience
• Design-build project experience
• AutoCAD experience
• Strong communication and coordination skills

What We're Looking For

We're not looking for:

• Project managers who no longer design
• BIM coordinators without engineering ownership
• Engineers who only review drawings
• HVAC-only specialists with little exposure to plumbing
• Candidates whose experience is primarily oversight-focused

We're looking for engineers who can confidently answer:

• "What systems did you personally design?"
• "What calculations did you personally perform?"
• "What construction documents did you produce?"
• "What engineering decisions were yours?"

Why This Opportunity Stands Out

• Immediate impact on active awarded projects
• Exposure to highly technical and complex facilities
• Strong project backlog and growth trajectory
• Opportunity to remain hands-on in design and engineering
• Hybrid work schedule after onboarding period
• Long-term growth potential
• Collaborative team environment focused on technical excellence

Target compensation generally falls within the $120,000-$150,000+ range, depending on experience, technical depth, and demonstrated design ownership. Exceptional candidates with strong production capabilities may be considered outside the typical range.
