Shape the Future of Optical Fiber Technologies

Birkerød, Denmark

We are looking for a curious and driven Senior Optical Engineer to join our Fiber Development team, reporting to the Engineering Manager. Whether your background is in industry or academia, your mindset matters most—curiosity, initiative, and a passion for exploring fiber optics and materials science.

In this role, you will take ownership of fiber design development, transforming experimental insights into tangible performance improvements while actively contributing to intellectual property and patent generation. We value a strategic mindset—someone who can connect detailed technical developments to the broader context and actively contribute to shaping technology roadmaps. You will work hands-on with advanced optical systems and contribute directly to the development of next-generation fiber technologies. You will design and operate experimental setups, including fiber characterization and amplifier systems, and analyze complex data to drive design improvements. With access to state-of-the-art laboratory equipment and simulation tools such as COMSOL, you will collaborate closely with our R&D teams to advance fiber designs and materials used in optical amplifiers.

We offer an environment where you can lead fiber R&D projects, shape technological direction, and continue to grow as a technical expert. Our team plays a central role in shaping our fiber solutions, and we are looking for someone who wants to make a meaningful impact.

Your Profile

You bring a structured and independent approach to your work, with the ability to manage development or research projects from concept through execution and reporting. At the same time, you are a collaborative team player who values knowledge sharing and continuous learning.

You likely bring a strong foundation in fiber optics and free-space optics, combined with hands-on experience in an optical lab environment. You are comfortable setting up and troubleshooting optical systems and enjoy working experimentally as well as analytically.

A PhD in Physics, Materials Science, Electrical Engineering, or a related field is expected, together with a genuine interest in staying up to date with developments in fiber optics, fiber lasers, amplifiers, and material science.
