Mechanical Engineer- Revit​/Federal Projects

Position: Mechanical Engineer- Revit / Federal Projects
Job Title:

Mechanical Engineer - HVAC & Plumbing ( Individual Contributor)

Location:

Irvine, CA

Work Model:
Onsite ramp → Hybrid (performance‑based)

Employment Type:

Long‑term consulting role with strong conversion intent

This role is for engineers who still do the work.

If you're a Mechanical Engineer who designs HVAC and plumbing systems, runs your own calculations, and produces construction documents in Revit, this is worth a conversation.

This opportunity supports mission‑critical federal and defense facilities where HVAC and plumbing systems are more complex than typical commercial buildings. Reliability, redundancy, and performance matter here-and engineers are expected to own their work from concept through construction documents.

This is not a project management role.

This is not coordination‑only or redline‑only.

This is a hands‑on production role.

What You'll Be Doing

You'll be a hands‑on mechanical contributor, owning real scope and producing immediately:

* Design HVAC and plumbing systems for complex facilities

* Run mechanical calculations independently, including:

* Load calculations

* Equipment sizing

* Pump calculations

* Produce Revit‑based construction documents (direct authorship required)

* Validate inputs/outputs and apply engineering judgment when results don't look right

* Support multiple projects concurrently in a lean engineering team

* Coordinate with architectural, electrical, and structural disciplines

* Participate in short, local site visits for field verification

This team needs someone who can produce immediately-this is not a training role for Revit or construction documentation.

Required:

* 5-10+ years of HVAC & plumbing system design experience

* Strong experience with mechanical calculations (loads, sizing, pumps)

* Proficiency in Revit MEP (current production experience required)

* Experience designing both HVAC and plumbing systems

* Experience producing construction documents (not just coordination/redlines)

* EIT required

Preferred:

* PE license

* Federal/DoD/VA project experience
