Prototype Engineer Full-time Job

Rotterdam, NL | Full-time | On-site Experience: 3+ years | Background: Industrial Design, Mechanical, Mechatronics, Applied PhysicsWe're building the future of smart glasses—and we need curious minds to help shape it!At our Rotterdam headquarters, we're developing a proprietary manufacturing process for prescription lenses tailored for Augmented Reality and smart eyewear. We’re a small, focused team solving one of the hardest challenges in wearable tech: delivering high-precision, thin, and scalable lens systems that work seamlessly with AR displays.We are looking to grow our Prototype Team—the core group responsible for prototyping, discovery builds for customers, and solving the technical challenges that come with being first. What You’ll Be DoingTurn customer designs into working lens prototypes, you own the whole process from A to ZValidate those designs for manufacturability—optical, mechanical, and all the in-betweensRun structured experiments to refine, stretch, or adapt the process to new challengesSolve tricky problems with smart, hands-on engineeringThis is lab-based, precision hardware work. If you like CAD, test benches, optics, and solving puzzles with your hands—you’ll fit right in. What We’re Looking ForA solid technical foundation (e.g. in mechanical engineering, industrial design, applied physics, or similar).At least 3 years of hands-on experience with prototyping—optics is a big plusA proactive mindset—you don’t wait to be told what’s brokenThe ability to bring structure to complex technical challengesIt’s not about being able to “handle chaos.” We want someone who can organize complexity and push things forward. What You’ll GetA Hard Challenge – We’re building something that doesn’t exist yet.

It’s deep-tech with real-world impact.Ownership – You’ll have real influence on the product, the process, and how we grow as a team.Growth – As we expand globally, you’ll be part of the team setting the standard for what comes next.Impact - Your prototypes go straight to some of the world’s most forward-thinking tech companies.Competitive Pay – We offer a solid salary, with plenty of upside along with company success.
