Variety, Growth, Support, Opportunity
Whether you are an intern or engineer, you will find opportunities to make an impact immediately.
We provide opportunity for advancement and resources for continuous growth.
Variety in your work is especially important for young builders. It offers exposure to different project types and responsibilities, facilitating personal growth and development. We provide both formal programs and a “lifelong learners” culture to support you.

I appreciated that, as an intern, I was given opportunities to stretch and expand beyond the traditional PE role. I was given responsibilities that had a real impact on the business, and my managers always took the time to provide coaching and feedback.

Midway through my internship, I was offered a full-time position. I didn't think twice about it–I signed it right on the spot. That's a testament to those teams and those projects and the opportunity I was given as an intern. And it has been nothing but a great opportunity and experience for me. This is home now.

As a civil engineering student at CU, my internship at W.E. O’Neil opened my eyes to an industry and career path that I had confidence would challenge me in ways that I hadn’t previously considered. I also found O’Neil had great values and appreciated their people—still true now after 23+ years with the company.

O’Neil is great at giving you space to grow your ideas in order to grow the company. My advice to young people is don’t be afraid to ask questions. Try to soak in as much information as you can from your team, especially the field team like subcontractors and superintendents.

Thoughtful leadership makes W.E. O'Neil better as a company in that it attracts the smartest and brightest people. People who want to be challenged and want to see their ideas put to use come to work for W.E. O'Neil.
What I'd say to construction professionals who are early in their career is: be eager but humble. Don’t try to come in as the boss; accept where you are at and grow from there. Seize every opportunity. Know that your opinion matters. Ask questions. Be the best at your CURRENT job.
I love the eagerness and curiosity of the new hires fresh out of school. They don’t know what they don’t know, but asking questions is a powerful tool! Watching them figure things out and succeed is truly a rewarding experience, especially when I’m helping them through that learning process.
The best way we can guide interns and recent grads is not only to set them up for individual success within that moment, but also into their future. It’s very rewarding to know that my guidance may become the foundation that defines their standard way of doing things in the future.
Mentors at WEO have taught me so many things, including that leadership principles aren’t just things you read in books. I’ve seen my mentors exhibit these in their lives, and the positive effects. Most importantly, I’ve learned that I can change and grow as a leader, even if it is hard.
