Rotterdam, NL | Full-time | On-site

Experience: 3+ years

Background: Industrial Design, Mechanical, Mechatronics, Applied Physics

We're building the future of smartglasses-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 Doing

• Turn customer designs into working lens prototypes, you own the whole process from A to Z
• Validate those designs for manufacturability-optical, mechanical, and all the in-betweens
• Run structured experiments to refine, stretch, or adapt the process to new challenges
• Solve tricky problems with smart, hands-on engineering

This 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 For

• A solid technical foundation (e.g. in mechanical engineering, industrial design, applied physics, or similar).
• 3 years of hands-on experience with prototyping-optics is a big plus
• A proactive mindset -you don't wait to be told what's broken
• The ability to bring structure to complex technical challenges

It's not about being able to "handle chaos." We want someone who can organize complexity and push things forward .

What You'll Get

• A 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.
• Impact - Your prototypes go straight to some of the world's most forward-thinking tech companies.
• Growth - As we expand globally, you'll be part of the team setting the standard for what comes next.
• Competitive Pay - We offer a solid salary, with plenty of upside along with company success.

You'll help shape products used by the next generation of AR devices-and be part of a team doing something no one else is doing (yet).
