We are looking for HW Sensing Engineer to help craft sensor for Oura in various modalities.

• →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%)
