Job Description

As a Hardware Interaction Designer at Sonova, you will play a key role in shaping how users experience our hearing instruments, chargers, Roger systems, and accessories — ensuring intuitive, seamless, and meaningful interactions across the entire product ecosystem.

You will collaborate closely with R&D, Product Management, UX, and Industrial Design teams to define how physical devices behave and how they connect with digital interfaces (apps and software). Your work will impact both end users (B2C) and hearing care professionals (B2B), contributing to a consistent and holistic experience across the Sonova ecosystem.

This is a highly cross-functional role where hardware, interaction design, and system thinking come together — from early concept definition through prototyping and validation.

More about the role

• 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

Must have

• Degree in Industrial Design, Interaction Design, Experience Design, Human Factors, or similar
• 3+ years of experience designing physical products or hardware interaction systems
• Strong experience in user-centered design methodologies in cross-functional environments
• Experience delivering end-to-end interaction design projects

• Skilled with CAD tools and Render Software (e.g., Keyshot)
• Strong ownership mindset — proactively drives projects forward and aligns stakeholders without waiting for direction
• Curious and confident mindset — able to challenge assumptions constructively and engage stakeholders
• Strong communication skills in English and ability to translate user insights into clear design requirements
