C3 is an engineering firm that designs and builds manufacturing equipment.

If you’ve recently bought a bed for school and it came to you rolled in a box, it’s likely the machine that packaged it was built by C3. This is one of the most disruptive industries – foam and mattress manufacturing. Our technology impacts multiple levels of its supply chain, from foam pouring to final mattress and bedding packaging for retail.

Our interns work as extra hands on our team. You’re assigned projects that you’ll see to fruition by the end of your internship. They have clear objectives and results you can show off on your resume.

Ive helped start up different machines on the floor, which allowed me to get familiar with the tangible, end product. In general though, I enjoy the design side more and am happy to have been able to spend much of my time working with PLC ladder logic, HMI design, and control panel layout and schematics.,” – Ben, Electrical Engineering Intern

Electrical Engineering Internship

As an Electrical Engineering Intern at C3, you’ll be assigned projects to develop and enhance our equipment designs. Past projects included updating HMI screens and improving communications between multiple machines in a system. We asses your strengths, interests, and our needs to find assignments that will work best for both of us.

We’re no longer accepting applications for Summer 2019.

Mechanical Engineering Internship

Mechanical Engineering Interns have their pencils and wrenches ready. They’re often found detailing mechanical drawings or serving as liaisons between the shop and engineers. They love figuring out how to make things work, and then make them work better.

Our Mechanical Engineers enjoy seeing a project through from start to finish. They don’t back down from problems that arise during assembly and are often running out into the shop to help. They are perfectionists with their designs and see their work as art.

We’re no longer accepting applications for Summer 2019.

“The pressure to perform at a higher level, that kind of challenge, it’s not something you get at school. You’re in class, you know what your expectations are, it’s very different here,” Braden, Electrical Engineer
