“Since starting with Duffy Engineering, I have been involved with a larger variety of projects in 4 months than in the 2 years with my previous firm. The collaborative and trusting environment provides the freedom and support to get involved in aspects of the business beyond my current knowledge base. As the company grows, I grow.”

Kevin Budd,
Sr. Building Enclosure Consultant
“Being part of Duffy Engineering has been a privilege. Even though I’m 2,980 miles away from the office, I still feel that the working environment is one of the best — and not just because I get to avoid traffic! hat sense of trust and support inspires me to show up every day and give my best.”

Executive Assistant

Our Core Values

Growth Mindset

We don’t believe in waiting your turn. We believe in earning it. Growth isn’t a perk here, it’s a priority. From mentorship to stretch projects, you’ll have room to challenge yourself and level up.

Authenticity

We want the real you. Strong opinions, unfinished ideas, and quiet instincts included. We value humility, humanity, and heart — not just polish.

Respect

On a small team, every interaction matters. With clients, contractors, and each other, we listen, we include, and we assume the best.

Communication

No politics. No guessing games. We value transparency, honest feedback, and clarity about how your work connects to the bigger picture.

How to Know if You’re a Good Fit

At Duffy, we look for people who care about doing things the right way — and doing them together. You’ll thrive here if you’re driven by curiosity, accountability, and a genuine desire to learn and contribute.

You might be a great fit if you:

  • See challenges as opportunities to problem-solve, not obstacles to avoid
  • Take ownership of your work and follow through on your commitments
  • Communicate clearly, even when the answer isn’t easy
  • Value teamwork and respect different perspectives
  • Bring both technical precision and practical judgment to the table
  • Enjoy learning from experience — yours and others’
  • Believe that good buildings, like good teams, are built with care
