Engineering Intern – Summer 2025

Fontaine Modification Company

Come join a team where People make the difference!  As a part of Marmon Holdings, Inc., a highly decentralized organization, we rely heavily on people with the aptitude, attitude, and entrepreneurial spirit to drive our success, and we're committed to attracting and retaining top talent.

Fontaine Modification Company (FMC) provides post-production modifications to commercial vehicles that bridge the gap between what OEMs can mass produce and what the customer needs to put the trucks to work. Products range from dual steering conversions, electric drivetrain installations, and extensive cab modifications to corporate graphics applications for large fleets. Locations adjacent to the OEM assembly plants allow vehicles to remain in the factory delivery system for nationwide distribution of “work-ready” trucks.
Since 1985, we have been the commercial truck modification leader.
Our in-depth technical and engineering expertise, coupled with our process quality and service capabilities, enables our customers to move their trucks into operation faster and with greater reliability.
We have ship-thru agreements with the leading Original Equipment Manufacturers (OEMs) to maximize end-user convenience and minimize delivery costs. These ship-thru arrangements expedite final delivery time from factories to destination with minimal financial impact. We provide engineering solutions to meet customers’ unique requirements and specific applications, all while adhering to federal safety standards.
Our reputation and history are built on our innovative solutions, excellence in engineering, superior workmanship, unmatched warranty, and outstanding customer service.
