Ready to start your career journey?

Our internship program is designed to give you hands on experience, lasting professional connections, and a foot in the door to an award-winning culture and endless opportunity.

Internships vary between divisions, but generally, you will do real work with responsibilities such as drafting and visiting job sites. Our experienced staff will guide and coach you just as they would if you joined us on a permanent basis.

As well as finding out how we work, you will also get to know who we are, from the manager who oversees your progress to the employees who work alongside you, to the “buddy” who acts as your informal coach and supporter. If you complete the internship program successfully, you may be offered a permanent role with us.

Our internship opportunities offer a chance to learn about construction outside of the classroom. Whether you are interested in project management, safety, pre-construction/estimating or a business-related role, an internship is a great way to gain exposure and identify specific interests. Our interns are paired with a senior colleague and join projects in the field or within departments.

Entry Level + Internship Opportunities – Three-week, full-time, and co-op internships available for fall, spring and summer semesters.

Internship Testimonies


“My time with O’Connell this summer has been an amazing experience. Being surrounded by a team of diligent and intelligent managers has allowed me to learn an immense amount about the bidding process and the industry as a whole. I look forward to utilizing the skills I have learned both in the classroom and here at O’Connell throughout the rest of my career. Thank you to everyone who has contributed to my great experience.”

“I enjoyed my summer at O’Connell tremendously! The employees make coming into work everyday something I can look forward to and really enjoy. Having the chance to learn new things each day and contribute to something that has a lasting impact on the company is a great feeling. I enjoyed going out on jobsites and working with real live equipment most this summer. O’Connell did a great job of taking me into live situations but always stressed being safe and how important safety was.”

“I started working with the Power Group at O’Connell during the pandemic when I was home from college, and it was the most valuable use of my time possible! I loved telling people that I worked at OCE because I was proud to work there, I felt like I was doing big things and contributing to the community in a cool way that worked with my skillset. I came in with little experience in this field, they took a chance on me, and as I learned more over time I was able to contribute more to bigger projects.”
