Mechanical Engineering Intern Fall 2026
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

📍 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.
If that sounds like your kind of challenge, apply.
