About The Position

Every day, patients recovering from stroke open our app to do their therapy. They count on it being fast, accurate, and smooth — in a clinic waiting room, at home, sometimes with only one working hand. nyra health builds the digital solutions that make neurological rehabilitation work outside clinic walls: myReha, the patient therapy app, and nyra insights, the clinician platform. 100+ clinics across DACH rely on both. We've raised €20M Series A and are scaling our team. nyra's Android app is the primary interface between patients and their recovery. It runs ML-powered speech feedback in real time, serves hundreds of therapy exercises, and must stay rock-solid across clinic tablets from 2018 and the latest Pixels. You'll join a small, strong Android team with real ownership and a direct impact on the product.
