Mechanical Engineer AddOptics Full-time Rotterdam, Netherlands Posted on Oct 13, 2026 Location : Rotterdam, NL Commitment : Full time Experience : 3+ years The Mission At AddOptics, we design and manufacture precision lenses for the next generation of smart eyewear. Our lenses integrate the newest technology (such as electronics and displays) seamlessly with vision correction, and allows the end user to experience the next generation of smart glasses in the most comfortable way. As we scale and expand our products and production capabilities we are also expanding our engineering team in our technology center in Rotterdam. As part of the engineering team, you'll take practical engineering challenges from problem to validated solution. You'll design the parts, tooling, and experiments to improve our products and processes. You can realize your designs using our our in-house R&D lab equipment, measure the results, and use the data to decide what comes next. Your projects can range from new lens designs and mold tooling to materials testing and manufacturing process improvements. This is hands-on, applied engineering: you design it, make it, test it, improve it, and prove that it works reliably. What You'll Be Working On - Owning mechanical development projects from problem definition through to validation of the results, as part of the engineering team. - Developing prototype product designs, tooling, processes improvements, and implementing them into a production process. - Designing backwards from the end-product requirements, considering materials, tolerances, manufacturing capabilities, and metrology. - Designing and running structured experiments that produce actionable conclusions. - Making, assembling, testing, and iterating parts using our in-house fabrication and casting capabilities. What We're Looking For - 3+ years of hands-on mechanical engineering experience - A BSc/BEng or MSc in Mechanical Engineering, Aer...
