Senior Android Engineer

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. What you'll work on • The therapy experience, end-to-end — you own the Android surface patients open every day as part of their recovery. Speech exercises, cognitive tasks, multimedia flows — you set the bar for how they feel, how fast they are, and how they grow. • ML in production — you're the bridge between our ML team's models and the patient's moment of use. You shape how speech feedback surfaces in the UI — latency, confidence, fallback states — so it feels instant and trustworthy. • Device performance — you own the performance envelope across older clinic tablets and modern phones: startup time, memory, jank, offline resilience. • Accessible product craft — partner with Product and Design on UI for users with partial mobility and cognitive load constraints • Engineering standards that scale — as one of the senior engineers on the Android team, you shape how the codebase grows. Architecture decisions, code review culture, testing strategy — what you establish now compounds as the team does. Requirements What sets you up • Strong track record on a scaling production app — you know what breaks under growth and how to prevent it • 5+ years of professional Android development in Kotlin • Strong grasp of Jetpack Compose, Coroutines, Hilt/Dagger, and MVVM/MVI architecture • Quality-focused engineering — smooth animations, responsive UIs, and craftsmanship even in a clinical context • AI-native development — we use Claude Code, Cursor, and AI-generated tests as daily infrastructure, not occasionally — and you bring this experience. • Comfortable working cross-functionally with Product, Design, QA, and backend • HTL/Bachelor/Master's in CS or comparable hands-on experience Nice to have: Firebase / NoSQL; multi-agent prompt chaining; performance profiling across device cohorts; offline-first sync strategies You'll thrive here if… • You think about the end user — a patient relearning to speak after stroke — and let that guide technical decisions • Performance on constrained hardware is a problem you've solved before and enjoy solving • You balance clean architecture with shipping value fast, and know when to favour each • You want to be close to ML/AI work, not just consume it Why nyra Patients first, always — everything we build is measured by patient outcomes, not engagement metrics. You're shipping therapy, not features. AI at the core — we integrate ML-powered speech recognition and therapy personalisation directly in the product. You'll work with the ML team, not just consume an API. Direct access — founders, ML engineers, and practicing clinicians are in the same room. Decisions move fast and you're part of them. AI-native culture — every engineer has Claude Pro and is expected to use AI tools daily. We're not experimenting; we've moved on. What we offer • Attractive compensation and Phantom Stock Options • €2,500 tech set up budget • Wiener Linien Yearly Ticket • Swapfiets bike • L&D budget • Claude Pro + AI tools • Flexible working hours and the possibility to work from home • Beautiful office in Vienna's First District The process • Intro call — background, motivations, role, and nyra ~30 min • Technical interview — walk us through a project you're proud of; we'll discuss implementation decisions, architecture, and what you'd change ~60 min • Founders' interview — your approach, technical philosophy, and how you'd shape neurotherapy on Android ~45 min Originally posted on Himalayas
