Job description

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 provide unprecedented reliability for the most business‑critical applications and our products are now also being used in building automation solutions.

Your future

We are looking for our next Senior Mobile App Developer to join our product development team within Entertainment Lighting. In this role, you will take on senior responsibilities and be accountable for the continued development and maintenance of our mobile applications for iOS and Android built with Flutter. While your primary focus will be within the Entertainment Lighting team, you will also be expected to manage multiple apps across different teams and projects, balancing the needs of each while keeping the overall architecture consistent and maintainable.

You will improve the existing user experience while exploring new ways for users to interact with our products. You will work closely with hardware and embedded teams to create seamless integrations between our products and mobile applications.

An important part of our approach to product development is having a deep understanding of our customers' challenges and a close understanding of the environment in which our products are used. As a senior developer, we expect you to be driven by a desire to understand the entertainment lighting industry. It is also important that you are comfortable navigating autonomously in vague and unfamiliar environments while being a solid and central team player who can support junior colleagues as well as consultants.

As part of maintaining a close dialogue with our customers and partners, we encourage you to participate in trade shows and engineering meet‑ups around the world approximately 2‑3 times per year.

About You

• Have a Bachelor's or Master's degree in Interaction design, Computer Science, Software Engineering or equivalent.
• Have experience developing Flutter applications for both Android and iOS, as well as some experience with native mobile development.
• Have an eye for user experience and an interest in creating intuitive interfaces.
• Are familiar with Figma and have the ability to work in it.
• Are curious about customers, their workflows and the market, and enjoy translating those insights into better products.
• Have an interest in embedded systems and hardware-related development, ideally with hands‑on experience using platforms such as Arduino, ESP32 or similar.
• Are curious and proactive, enjoy exploring unfamiliar technologies, and continuously seek opportunities to improve our products and development practices.
• Are fluent in English, written and spoken.

It Is Advantageous If You Also Have

• Experience publishing and maintaining applications in Google Play and App Store.
• Experience with Bluetooth/BLE or wireless networking (Bluetooth/BLE, Zigbee, WiFi, LoRa, Thread, 6LoWPAN, NB‑IoT, 5G etc.).
• Experience from the entertainment lighting industry.

Our tech stack

• Whatever OS and editor that make you productive.
• Flutter.
• GitLab and GitLab CI.
• Bluetooth (mainly BLE).
