Senior Android Engineer

  • On-site, Remote, Hybrid
    • Vienna, Wien, Austria

Job description

Build the app that helps people find their words again.

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.

Job 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

  1. Intro call — background, motivations, role, and nyra ~30 min

  2. Technical interview — walk us through a project you're proud of; we'll discuss implementation decisions, architecture, and what you'd change ~60 min

  3. Founders' interview — your approach, technical philosophy, and how you'd shape neurotherapy on Android ~45 min
