Lens Development Engineer
At IXI, we’re on a mission to transform the way the world sees. Our IXI Adaptive Eyewear is revolutionizing the eyewear industry, bringing cutting-edge technology to vision correction. Our glasses are equipped with dynamic lenses, intelligent frames, and real-time gaze recognition, providing naturally sharp vision in any situation.
Our team of experts in optics, medical device engineering, consumer electronics, and design is united by a common goal: to break the limits of traditional eyewear and change the way glasses are made.
Join our team as Lens Development Engineer
We’re looking for a Lens Development Engineer to join the team developing a key part of our product: the lens. In this role, you’ll design new and improved lens iterations, using measurements and data from previous versions to guide your work.
This is a hands-on role where you’ll spend your time both developing designs and diving into the underlying optics, as well as running measurements and analysing results yourself. You’ll work closely with the lens, product, and mechanics teams to ensure designs meet real-world requirements, including performance and manufacturability.
If you have a background in physics or optics and some experience with programming, ideally in Python, this is a chance to apply your skills in building a category-defining consumer product.
What You'll Do
Design and develop new adaptive lens designs combining traditional optics and liquid crystal technology
Build, test, and validate designs through hands-on measurements and analysis in the lab
Work in a continuous loop of prototyping, learning, and improving designs
Try out new ideas and approaches, even if they are unconventional
Turn optical concepts into practical solutions that can be manufactured
Collaborate closely with product, mechanics, manufacturing and lab teams to bring designs to life
Help bring our current lens to production and then contribute to developing the next generation
Share progress, ideas, insights, and challenges openly with the team
What You Bring
A background in physics, materials science, optics, photonics or a similar field
Programming skills, ideally in Python
Hands-on experience with optical design, testing, or experimental work
Ability and interest in working practically, not just theoretically
A curious and experimental mindset, with a willingness to learn and iterate quickly
Good communication skills and a collaborative way of working
Comfort working in an environment where things are still evolving
Ability working in English and onsite in our Espoo office
What We Offer
Join a deep tech company that is truly disrupting the eyewear market – backed by $36.5M in Series A funding.
Work on something that’s genuinely new - a blend of precision optics, advanced materials, and intelligent automation.
A small, diverse, and international team where every voice counts and new ideas are encouraged.
Modern lab and workshop environments with space to build, test, and iterate.
Competitive compensation (incl. stock options) and comprehensive benefits package, including extended healthcare and benefits for lunch, sports, recreation, massage, and commuting.
