Original job description

Senior Mechanical Engineer (HVAC)

Type: Full-time, direct hire

A well-established, 1,000+ employee design-build mechanical contractor headquartered in St. Louis is looking for a Senior HVAC Design Engineer. They need someone who can mentor and still produce at a high level. This is a hands-on senior seat with real ownership of projects and a chance to shape the next generation of engineers.

You’ll work in a design-build and design-assist environment. Your designs are fabricated and built in-house, so you see the results of your work and collaborate directly with construction, fabrication and preconstruction teams.

What You’ll Do

Run your own design projects from start to finish in Revit, including more sophisticated, complex jobs
Design HVAC and mechanical systems across a wide range of system @types
Mentor and guide junior engineers, primarily on simpler projects
Partner with construction, fabrication and preconstruction teams in a design-build/design-assist model

What You Bring

Roughly 10-15 years of HVAC/mechanical design experience
Broad knowledge of mechanical design systems (a generalist’s range, not a single-system specialist)
Proven ability to run your own projects in Revit
A genuine willingness and ability to mentor while still producing your own work
Residence in the St. Louis area, or a manageable commute

Preferred, Not Required

Professional Engineer (PE) license. Ideal, but not a deal breaker. Missouri licensure or the ability to obtain it by comity is a plus.
Design-build or contractor-side experience
Project experience in healthcare, labs/pharma, mission critical, higher education or industrial facilities

Why This Role

See your work built. Design-build means you watch your designs get fabricated and installed in-house.
Varied, complex projects. Pharma and labs, healthcare, data centers, aviation, manufacturing, food and beverage, and education.
Ownership and influence. This is a senior seat with real autonomy and the chance to build up the engineering bench.
Stability and scale. A company with more than a century of history, a St. Louis headquarters, and a presence in multiple states.
Live and work in St. Louis. A strong Midwest engineering market with a lower cost of living than many comparable metros.

Take the next step in your career and APPLY NOW. You can also reach me directly at 612-473-3065 or David.Gunderson@gogpac.com
