Mechanical Engineering Intern Fall 2026 Onsite (Billerica, MA)

Fabri is a funded hard-tech startup reimagining how foundries operate—from raw material to finished part—through a fully digital, end-to-end system. This summer, we're opening the doors to a hands-on builder who wants more than just another internship. If you're the kind of person who would rather prototype than theorize, turn a wrench instead of defer, and see your work running on real equipment—not just in CAD—this role is for you. As a Mechanical Engineering Intern, you'll join a tight-knit engineering team working on Phase 1 of our digital foundry. You won't be sidelined—you'll help design, build, and refine the systems that make it all work. What You'll Actually Do Design and build mechanical systems and fixtures that operate in a real foundry environment Print and process production and development parts at Fabri's resin print farm. Rapidly move from concept CAD fabrication test (and iterate just as fast) Work with machining, fabrication, tolerancing, and thermal/structural analysis—often on problems you haven't seen before Troubleshoot across disciplines: mechanical, thermal, and process-related Contribute directly to the tooling, fixtures, and automation hardware that are core to Fabri's platform What Makes This Different Your work won't sit in a demo bin—it'll be used You'll have real ownership, not just tasks You'll learn by doing, not by watching You'll be surrounded by people who build fast and expect the same What We're Looking For Current student or recent graduate in Mechanical Engineering, Manufacturing, Robotics, or a related field Experience running resin 3D printers Strong hands-on experience designing and building mechanical systems CAD proficiency (SolidWorks, Fusion, or similar) and solid general computing skills Shop experience (machining, welding, fabrication) is a plus Curiosity, initiative, and a bias toward action Details On-site: 35 Dunham Road, Billerica, MA Paid internship (Summer 2026) Due to ITAR regulations, candidates must be U.S. citizens or lawful permanent residents. This is a chance to step into a real engineering environment, contribute to systems that matter, and leave the summer with experience you can actually point to—and explain. #J-18808-Ljbffr S27a
