ŌURA

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 2.5 million 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 are looking for a Health Sensing Hardware Engineer to join our hardware team working on future wearables and accessory devices reporting directly to the Director, Hardware Sensing Technologies. This opportunity will be hybrid out of our San Francisco or San Diego office.

What You Will Do

Develop and validate physiological sensing systems for acquiring and analyzing physiological signals in wearable health and wellness products

Define hardware and software technical specifications and implement test and calibration protocols both internally and at manufacturer sites

Ensure that the physiological sensors integrated in our products meet their specifications from prototype to mass production

Build and validate hardware architectures optimized for low-noise, high-resolution time-series signal collection

Plan and execute benchtop and on-body testing to evaluate system performance across various user populations

Support validation and compliance efforts in collaboration with regulatory, research, and clinical teams

Work cross-functionally to ensure end-to-end system performance and signal integrity

Conduct rigorous testing and troubleshooting to ensure sensor performance across varying environmental and use-case conditions

Collaborate closely with mechanical and electrical engineers to integrate sensors within constrained form factors and flexible layouts

Partner with firmware and software teams to enable and refine features built on physiological data

Work directly with sensor vendors to evaluate new components, optimize performance, and address integration challenges

Travel occasionally to Finland and to global manufacturing or development sites as required (15%–20%)

Requirements
