Empowering the world starts with living our values and empowering our team. As a quickly growing company focused on helping people live healthier and happier lives, we ensure that our team members have what they need to do their best work — both in and out of the office.
We are seeking a Senior ML & Biosignal Scientist to join our Future Physiology team in Finland. This is a high-impact role for a deeply technical, hands-on expert who excels at bridging human physiology, machine learning, and real-world biosignal R&D. Working directly alongside our world-class hardware, firmware, software and science teams, you will play a pivotal role in shaping Oura’s next-generation features. You will turn noisy, multimodal sensor data (including PPG, motion, and temperature) into robust, scalable, and actionable health insights delivered to millions of members worldwide.
What You Will Do:
- Take full technical ownership of the algorithm lifecycle, from physiological background and signal processing to model architecture design, evaluation, and scaling for production.
- Develop and deploy state-of-the-art ML algorithms leveraging deep learning (e.g., Transformers, RNNs, probabilistic models) to extract meaningful physiological metrics across diverse user populations, effectively solving real-world challenges such as motion artifacts and environmental noise.
- Leverage Oura’s large-scale cloud datasets and work hands-on with prototypes, hardware evaluation kits, and benchtop testing setups.
- Translate complex algorithmic results and physiological insights into clear technical strategies and strategic narratives for senior leadership to help guide Oura’s future product roadmap.
This is a hybrid role out of our Oulu or Helsinki office.
What you'll bring
- 5–7+ years of hands-on experience in machine learning, biosignal processing, sensor fusion, and analyzing real-world, multimodal time-series data.
- Expertise with modern ML frameworks (PyTorch) alongside the scientific computing stack (NumPy, SciPy, pandas, scikit-learn).
- Strong domain knowledge of human physiological systems underlying wearable biosignals, paired with the engineering intuition needed to extract clean signals from noisy data.
- Familiarity with modern data infrastructure, scalable cloud systems, and a proven track record of moving ML models from experimental research into production software.
- Master’s or PhD in Computer Science, Machine Learning, Biomedical Engineering, Signal Processing, Applied Mathematics, Physics, or a closely related field (or equivalent practical track record).
- Comfortable working in an agile environment with high autonomy, taking complete ownership of algorithm development from early-stage concept testing to deployment.
Nice to have:
- Direct experience in consumer health tech, wearable hardware or digital health applications.
- Prior experience working within cross-disciplinary teams spanning software engineering, hardware development, and clinical research.
