Co-ops and Internships

Messer can give you more than job experience. You can see what it feels like to be an employee-owner, grow professionally and make an impact on the team and community.

Co-op Tour

Career experience and so much more

Each year, more than 100 students participate in the co-op program across all of our regions, and this number continues to grow. It’s your career path, and we want to support your growth. The co-op/internship program has a lot to offer:

  • You get to learn more about your career interests from day one.
  • You can move around to try different things and get a feel for where you excel.
  • You are treated like an employee with a focus on valuable work, not busywork.
  • You are part of something bigger than yourself—literally—because Messer builds commercial construction in aviation, federal/military, health care, higher education, industrial, science and technology, and more.
  • You can work in one of our 10 regions or the corporate office in Cincinnati.

Our most regularly offered co-op positions include: Project Engineer, Estimating, Building Systems Engineer (MEP), Accounting, Human Resources, Information Technology, Safety, Virtual Design & Construction (BIM) and Risk Management.

Please be aware, it is not the practice of Messer or any of our subsidiaries to request personal information or conduct employment interviews via email or web chat. The safety and protection of your personal information are our top priorities. All offers of employment include face-to-face interview.
