Hvac Engineer

Actalent • Irvine, CA • 13h ago

Mechanical Engineer - HVAC & Plumbing (Mission-Critical Facilities)

Location: Irvine, CA

Work Model: Onsite ramp Hybrid (performance-based)

Employment Type: Long-term consulting opportunity with strong conversion intent

This role is for engineers who do the work.

If you're a Mechanical Engineer who still designs systems, runs calculations, and owns deliverables-and you're tired of roles that are drifting toward coordination, redlines, or meetings-you'll want to read this.

This opportunity supports mission-critical federal and defense facilities where HVAC and plumbing systems are far more complex than standard commercial buildings. Think facilities where ventilation, redundancy, and performance actually matter.

What You'll Be Doing

You'll be a hands-on mechanical contributor, working under senior guidance while owning real scope:

Design HVAC and plumbing systems for complex facilities

Run mechanical calculations independently, including:

Load calculations

Equipment sizing

Pump calculations

Produce and contribute directly to Revit-based design documentation

Apply engineering judgment-not just software outputs-when results don't look right

Support multiple projects simultaneously in a lean, technical team

Coordinate with architectural, electrical, and structural disciplines

Participate in short, local site visits for field verification

This is not a PM role and not a redline-only position.

What Makes This Role Different

Execution matters here - titles and licensure don't replace doing the work

You'll work on federal and defense infrastructure, not generic commercial buildings

Systems are technically challenging and purpose-driven

senior engineers want support from someone who can carry real design load

Clear expectations, fast decisions, and low politics

This Role Is a Fit If You Can Honestly Say:

"I designed this system."

"I ran these calculations."

"I produced these Revit drawings."

"I've done this on more than one project."

Minimum Qualifications

5-7+ years of mechanical building systems experience

Hands-on HVAC and plumbing design experience (both are required)

Strong background in mechanical calculations

Revit experience (prior production use required; refresher acceptable if rusty)

Ability to work onsite during ramp-up

U.S. citizenship (required for federal project access)

Nice-to-Haves

EIT or PE (helpful, not required)

Federal / VA / DoD project experience

Industrial or medical facility exposure

Controls coordination experience

Not a Fit If...

Your recent roles were PM-only, coordination-only, or oversight-focused

You haven't personally designed systems or run calculations in years

Your experience is HVAC-only with little or no plumbing

You're looking for a fully remote role

Compensation

$120,000 - $150,000 base (DOE)

Compensation is tied to hands-on execution, technical depth, and independence-not just years or credentials.

Why Engineers Choose This Team

High-impact, technically challenging work

Long-term stability with real conversion intent

Hybrid flexibility once you've proven yourself

A culture that values engineering judgment and ownership

Interested?

If you're an engineer who still enjoys designing, calculating, and solving real problems, this is worth a conversation.
