Summary
👤
Senior🎓
Top SchoolMattias Johansson is a systems engineer based in Stockholm with 10 years of experience designing embedded and automotive systems, currently contributing to product and concept development in aviation at ST Airborne Systems. His background spans sensor platforms, perception software and regulatory coordination for autonomous transport at Scania, complemented by hands-on embedded development and MEMS design earlier in his career. He blends systems thinking with practical firmware and backend experience—evidenced by open-source contributions to Volumio where he implemented I2S DAC support, MPD restart logic and improved web socket and alarm/webradio features. Comfortable switching between product ownership, regulatory responsibility and low-level engineering, he has a track record of turning complex hardware-software interactions into deployable features. Mattias holds a Master’s in Applied Physics and Electrical Engineering from Linköping University and often bridges domain knowledge with pragmatic implementation. A less obvious strength is his knack for smoothing transitions between concept and regulated product deployment, making him effective where innovation meets compliance.
