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.

Replacing cables in buildings and lighting control systems with wireless communication makes installations easier, more flexible 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.

In our General Lighting team, we work with W-DALI and AirGlow to bring reliable wireless lighting control to real-world environments, using existing DALI systems and without the need for cabling. In our Building Controls team, we work with W-Modbus and W-BACnet to replace cables in buildings, such as HVAC systems and solar installations. You will be part of our R&D organization, where we continuously develop and refine wireless communication technology.

Your future We are looking for a Technical Support Engineer to join the team, supporting our DALI lighting control solutions, and building automation products, W-Modbus and W-BACnet.

In this role, you will take ownership of post-sales technical support, working closely with customers such as lighting designers, installers, electricians, and system integrators. You will operate mainly as a 2nd – 3rd line support function, collaborating with distributors and internal development teams to troubleshoot and resolve issues, often related to configuration, system setup, and 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 the link between customer needs and our product organization.

The position is primarily based at the office in Gothenburg, with travels approximately 5–7 times per year for trade shows or visiting customers around the world.

• Hands-on experience in configuration and troubleshooting lighting installations and/or building control systems, preferably as an installer or electrician
• Experience with DALI, Modbus, BACnet, or similar protocols
• A hands-on, curious mindset with interest in electronics (e.g. Arduino, soldering) as well as experience supporting electronics manufacturers or hardware integration projects is a plus
• Fluent in English and Swedish, both written and spoken
