Mechanical Engineering - Reliability Intern (Fall 2026)

Do you want to change how the world creates?

At Formlabs, we’re building the tools that make it possible for anyone to bring their ideas to life, from cutting-edge products to life-saving medical devices. Our 3D printing technology powers innovation at more than 50,000 industry leaders worldwide, including Apple, Google, Tesla, New Balance, and NASA. Together, we’re helping everyone design, prototype, and manufacture faster than ever before.

We’re a team of hands-on builders, engineers, and innovators reinventing how the world makes physical things. If you’re ready to shape the future of fabrication, come build it with us.

We’re looking for a R&D Test Engineer who will play a key role in running tests and partner closely with the engineers to perform systemized tests on 3d printers and report your findings. The output of this work will determine future features and settings for our 3d printers.

The Hardware Reliability Engineering team ensures that Formlabs products in development are reliable and ready to ship, as well as triaging reliability issues of current products already in the field. We work closely with design teams of all disciplines to find product flaws as fast as possible and then work on redesigns to make more robust systems.

Are you a cross-functional engineer that is passionate about creating robust products? We want you as a Hardware Test Engineering Intern.
