Lead Sensors Engineer

As the first Hardware Engineer, you will own the full non-EEG sensor system for a next-generation AI companion wearable, focusing heavily on PPG technology to deliver accurate heart rate and HRV signals during motion. You will lead end-to-end R&D for architecture, hardware selection, and algorithms while partnering with external manufacturers and internal teams to ship the product by year-end. This role requires deep expertise in sensor fusion, analog front-end design, and bringing hardware solutions from concept to market for a novel category of consumer wearable.
