Optical Systems Engineer

Optical Systems Engineer AddOptics Software Engineering Rotterdam, Netherlands Posted on Sep 14, 2026 Physics, Simulation & Hard Problem Solving Location : Rotterdam, NL Commitment : Full time Experience : 5+ years The Mission At AddOptics, we develop next-generation ophthalmic and vision solutions. We're a small, fast-moving tech team where every person owns their domain. We're looking for an Optical Systems Engineer who thrives on solving the hard problems - someone who can model a lens stack from first principles, run the simulations, and give the rest of the team a clear answer when the physics gets complicated. What You'll Be Working On - Building and running optical simulations of complex lens stacks - multiple surfaces, curvatures, air gaps, materials - and knowing what the output actually means - Developing simulation frameworks and scripts that let the team interrogate optical performance quickly and reliably - Challenging and validating design assumptions - if the numbers don't add up, you find out why - Learning the ophthalmic domain (Rx language, dioptric power, prescription-to-optics translation) and becoming the person who bridges that gap internally - Working directly with engineers on live customer projects as the go-to source of optical truth What We're Looking For - A strong foundation in physics - you understand what's happening at the wavefront, not just what the software puts out - 5+ years of hands-on experience in optical design and simulation - Proficiency in OpticStudio (Zemax), CODE V, or equivalent optical design tools - Comfort with scripting or coding to automate or extend simulations (Python, MATLAB) - Experience designing optical systems with multiple refractive elements, curvatures, and air gaps - Familiarity with ophthalmic optics or a genuine appetite to learn the domain fast - The ability to communicate clearly with non-optical engineers - you can explain what the simulation is tell...
