The OpenEarable platform is the world’s first fully open-source AI platform for ear-based sensing with true wireless audio. It integrates a rich set of sensors (IMU, pressure, temperature, optical PPG, microphones, LEDs, speaker) in a compact, modular design, enabling applications in biosensing, motion tracking, and real-time interaction via BLE and mobile apps. More information: OpenEarable.

The TECO research group at the Karlsruhe Institute of Technology (KIT) is seeking a motivated Research Assistant (wissenschaftliche Hilfskraft) to focus on firmware development for OpenEarable, with additional tasks in mobile app development.

• Develop and optimize embedded C++ firmware for microcontrollers
• Perform hardware-near programming (sensor interfacing, I²C, SPI, PDM, BLE)
• Implement and test drivers, real-time data processing, and system integration
• Contribute to the OpenWearable App with Flutter (Android/iOS) for device control and visualization

• Strong C++ skills for embedded/firmware projects
• Experience in hardware-near programming and embedded toolchains
• Desirable: Experience with ZephyrOS and BLE communication
• Desirable: Flutter knowledge for cross-platform mobile development
• Independent, structured, and team-oriented work style

• Work in an open, cutting-edge research project at TECO, KIT
• Involvement in both firmware and app layers for a real-world wearable platform
• Flexible working hours in a collaborative team environment

For application, please send CV, short motivation letter, and relevant documents as your application.
