You will work closely with firmware, AI / ML, biomedical, and mobile teams to create a seamless, secure, and scalable digital ecosystem that powers our global wearable intelligence platform.

You will be a key member of the  core founding team , owning major components of ONLYQ’s backend and contributing directly to its global launch roadmap.
