Jendi AI puts people back in command of their wellbeing. We harness real-time signals from the body to unlock personalised, data-driven experiences—powered by deep tech, guided by science, and built with privacy at the core.
By translating raw biomarker data into meaningful insights, we enable more responsive, intelligent systems that adapt to how people actually feel—improving sleep, focus, resilience, and everyday performance.
This is intelligence-driven health recovery, re-engineered—and you’ll be central to making it happen.
We’re looking for a Mobile App Developer Intern (Swift or Flutter) who’s passionate about health tech and excited to build high-impact user experiences. Whether you write native Swift for iOS or love the speed and elegance of Flutter, you’ll be developing the core interfaces that help users recover better, sleep deeper, and live stronger.
