Mechanical Engineering Intern Summer 2026

Mechanical Engineering Intern
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.

Overview
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.

Who we’re looking for
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.

Responsibilities

Design and build mechanical systems and fixtures that operate in a real foundry environment

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

Qualifications

Current student or recent graduate in Mechanical Engineering, Manufacturing, Robotics, or a related field

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.

If that sounds like your kind of challenge, apply.
