Hardware Interaction Designer

Design intuitive interaction concepts for hearing devices, chargers, Roger systems, and accessories. Define how users physically interact with products (wearing, inserting, charging, pairing, controlling, feedback). Develop hardware UX concepts that improve usability, comfort, aesthetics, and user confidence. Translate user insights into clear design principles and requirements for R&D teams. Build and test physical prototypes and interaction mock-ups (3D printing, Arduino/Raspberry Pi prototyping). Create storyboards and end-to-end user journeys across real-life usage scenarios. Ensure seamless alignment between hardware behavior and digital interfaces (apps/software). Collaborate in an agile, cross-functional environment and drive alignment across stakeholders.
