LumenRadio is a high-tech company with the vision of replacing all cables in the world. We have been leading the wireless
transformation within the lighting industry since 2008, where our technology is being used every day in the largest TV and Movie
productions in Hollywood, at the Coachella festival, and the Eurovision Song Contest. Our patented technologies deliver
unprecedented reliability for the most business-critical applications, and our products are now also used in permanent indoor and
outdoor lighting installations, as well as in building automation systems.

and more cost-efficient. With rising demands for energy efficiency, wireless control has become a key enabler, making intelligent
control possible even where traditional cabling is not.

interoperability. The role may also include handling RMA cases and supporting more complex investigations, occasionally on-site.
In addition to day-to-day support, you will contribute to improving support flows, documentation, and product quality by providing
structured feedback and technical insights to product management and development. You will play an important role in strengthening
