Senior Project Engineer - Mechanical

Overview

MSA Professional Services is looking for a Senior Project Engineer Mechanical to lead the design of HVAC, plumbing, and mechanical systems for K-12 schools, municipal buildings, and other commercial buildings. In this role, you will be a key contributor in developing energy-efficient, sustainable, and code-compliant mechanical designs for facilities that shape our communities—from classrooms and gymnasiums to fire stations and city halls.

 

This role combines technical leadership with meaningful client engagement. You'll work closely with architects, other consulting engineers, and building owners to deliver systems that prioritize occupant comfort, indoor air quality, long-term operational efficiency, and community impact.

 

Who we are:

For over 100 years, MSA has helped shape communities through engineering excellence. What began in 1919 with a single practitioner in Baraboo, Wisconsin, has grown into a robust firm of over 500 employee owners across the U.S.

 

Our purpose is simple: to make communities stronger, safer, and more sustainable. We believe in the power of relationships, trust, and doing the right thing — and we take pride in seeing our work come to life.

 

At MSA, we understand that great work happens when you contribute great value, and maintain a balanced life and career.  That’s why we offer:

• Employee Ownership = True Investment: MSA is a 100% employee-owned firm. That means when you join our team, you’re not just doing a job — you’re building your legacy and sharing in the success of the firm.

• A Culture of Mentorship and Collaboration: Work alongside a talented, cross-disciplinary team that values mentorship, professional development, and team success.

• A flex time program that empowers you to manage your schedule — because life doesn’t always fit inside 9 to 5

• A flexible work environment, including hybrid and remote options where possible, to support your productivity and well-being
