Senior Human Factors Researcher

Our mission at Oura is to empower every person to own their inner potential. Our award-winning products help our global community gain a deeper knowledge of their readiness, activity, and sleep quality by using their Oura Ring and its connected app. We've helped millions of people understand and improve their health by providing daily insights and practical steps to inspire healthy lifestyles. 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're looking for a Senior Human Factors Researcher to join our Design Research team. This role is ideal for a researcher with a deep technical background in physical hardware and ergonomics who's ready to own end-to-end research for our next generation of wearable technology. As a Senior Researcher, you'll be a key contributor to the design and development of Ōura rings, ensuring our devices deliver world-class comfort, fit, and usability. You'll work hands-on with Industrial Design and Hardware Engineering to translate complex human data into actionable design requirements, and you'll help non-technical teams reason about and apply that data in their own work, interpreting human modeling data to evaluate form factors, pressure-test fit and comfort hypotheses, and turn findings into concrete direction. This is a hybrid position. You will be expected to be in the SF or Helsinki office 2-3 days a week depending on the schedule, potentially more days if running a study. What You'll Do Own end-to-end research. Plan and conduct human factors and ergonomics evaluations across the full product lifecycle, focused on how users physically interact with wearable hardware and how form factor choices perform against the underlying human data. Collaborate deeply across functions. Work closely with industrial and product designers, fellow human factors researchers, electrical and mechanical engineers, and program management so that form factor evaluations answer the questions that matter most for the product. Translate data into design requirements. Convert anthropometric and human modeling findings into concrete, actionable parameters, sensor placement, sizing, geometry, and materials. Deliver insights that drive decisions. Produce high-impact findings that directly shape hardware decisions and support critical product validation milestones. Champion human factors and human modeling. Advocate for the value of human factors in the design and development process. Utilize human modeling data in form factor evaluations, sizing, and, helping non-technical teams interpret and apply it confidently to their workflows. Support quality and compliance. Contribute to the documentation required for quality assurance and future regulatory submissions. What You Likely Have Education: A Master's or Ph.D. in a field related to the human body, measurement science, body modeling, statistics, design integration, or applied human factors e.g., Human Factors, Ergonomics, Biomechanics, Biomedical Engineering, Biological Anthropology, Computer Vision, Geometric/Computational Modeling, Machine Learning, Statistics, Data Science, ME/EE, Physics, HCI, Cognitive Psychology, or Anthropometry/Kinesiology. Experience: 5+ years conducting human factors research focused on physical hardware, wearables, or body-worn technology Working with human modeling data: Experience interpreting and applying 3D anthropometric datasets (e.g., from photogrammetry, laser scanning, or MRI) to inform product parameters and form factor decisions. Possess a strong fluency as both a consumer and an analyst of this data. Technical expertise: Strong command of ergonomic and anthropometric principles and how to apply them to hardware development, including evaluating comfort and fit across a diverse global population.
