Machine Learning Researcher

As our ML Researcher, you’ll report to our Head of ML and own research on nyra health’s neurological speech data, taking ideas from first experiment through to models that run in myReha and nyra insights. You’ll work closely with our Engineering team to bring models into production on-device and in the cloud. You’ll also work alongside our therapists, clinicians and product team, who know the patient problems firsthand and will help you decide which ones are worth solving. You’ll collaborate directly with the founders on nyra’s ML research roadmap, and with our academic partners on publications and joint research projects. It’s a role with a lot of autonomy and real scientific ownership.

About nyra health

Every morning, thousands of people relearn to speak with myReha, and your models listen to every attempt. nyra health builds the digital tools that make neurological rehabilitation work inside and outside clinic walls: myReha, the patient therapy app, and nyra insights, the clinician platform.

100+ clinics, 100K+ patients across DACH.

3× MRR growth target for 2026. €20M Series A. Team of 30+, scaling to ~50 this year.

Ownership, excellence and patients first — that’s how we drive progress together.

You care about doing things right — proper evaluation, reproducibility, and honest assessment of what works and what doesn't Impact-oriented: You're motivated by building models that ship and make a difference, not just benchmarks

You enjoy working with clinicians, therapists, and product teams to understand the problems worth solving Self-directed: You can identify promising research directions, design experiments, and drive projects forward with minimal guidance

You find the intersection of AI and human communication fascinating — especially in populations underserved by existing technology

Why nyra health

• A better pronunciation score means more accurate feedback for a patient relearning to speak, every single day.
• We build for better patient outcomes.
• Discuss your research vision, how you'd leverage nyra's data assets, and how you see the future of AI in neurological care.

Responsibilities

• Your work goes straight to patients relearning how to speak, not to a benchmark leaderboard.

What you'll shape

• Develop and improve models for neurological speech recognition, pronunciation scoring, and phoneme-level analysis — building on our proprietary models
• Research and prototype models for therapy content generation, patient progress prediction, and clinical decision support
• Explore combinations of speech, text, and behavioral signals to build richer models of patient recovery
• Design evaluation frameworks, build training pipelines, and establish rigorous benchmarks for model performance in clinical contexts
• Contribute to scientific publications and collaborate with academic partners on research projects
• Work with Engineering to deploy models into our production stack — ensuring they run reliably at scale on-device and in the cloud
• Help shape nyra's ML research roadmap, identifying high-impact opportunities at the intersection of AI and neurological rehabilitation

Requirements

• You use AI tools daily — Claude Code, Cursor, Copilot, or similar — not as a novelty, but as your default way of working.
• You write better code faster because of it.
• You're comfortable orchestrating multiple AI agents, chaining prompts, and building workflows where AI handles the heavy lifting while you steer the outcome.
• Hands-on experience with PyTorch, model training at scale, and modern training techniques (LoRA, RLHF, distillation, etc.) Research rigor: Track record of publications, open-source contributions, or documented research projects Engineering skills: Ability to write clean, production-quality
• Python code — not just notebooks
• Experience designing experiments, defining metrics, and drawing valid conclusions from data

Preferred

• You actively shape your own dev environment — custom scripts, automation, MCP servers, CLI tools — and you're always looking for ways to remove friction from your workflow.
• MSc or PhD (or equivalent practical experience) in machine learning, speech processing, NLP, or a related field
• Strong background in speech recognition, speech synthesis, audio processing, or related areas (experience with Whisper, wav2vec, HuBERT, or similar architectures)
• A research discussion covering your past work, approach to a relevant problem, and a technical scenario, with our ML and Engineering leads.

Your work gives our teams more time to focus on the people delivering and receiving rehabilitation.

Ownership & direct access

See the impact of your work and take responsibility for outcomes. Founders, ML engineers and practicing clinicians work closely together, so decisions move fast and you’re part of them.

Transparent, direct culture

Open communication and honest feedback are how we operate.

AI-native

Every team member has Claude Pro and is expected to use AI tools daily. Some of the best Mario Kart drivers in the Austrian startup scene 😉 The Process Intro call (~30 mins): Background, expectations, and an overview of nyra health and the role.
