R&D Prototyping Technician (Contract), Advanced Experiences

Sonos is looking for a hands-on R&D Prototyping Technician to support the Advanced Experiences team in London during a key period of experimental work, hardware prototyping, and data collection.
This role is ideal for someone who is technically capable, detail-oriented, and comfortable working with physical prototypes, lab setups, and structured research protocols. You do not need to be a specialist in sensing or signal processing; success in this role will come from being practical, reliable, organized, and confident working with experimental hardware under the guidance of research leads.
The contractor will help ensure continuity across hardware builds, prototype iteration, user data collection, and documentation. This is a primarily on-site role in the Sonos London office near London Bridge due to the hands-on nature of the work.
