Job Description
Senior Sensors Engineer (Contract) Company Overview Sabi is developing a next-generation AI wearable that combines ultra-high-density neural sensing with a Brain Foundation Model to decode neural signals and convert thought into text without surgery. The company is focused on advancing noninvasive brain-computer interface (BCI) technology through an EEG-powered wearable platform. Position Summary This person will own the end-to-end non-EEG sensor architecture, hardware, and algorithms for a sensor-rich wearable platform. The primary focus is PPG sensing systems, including optical hardware, heart rate, HRV algorithms, and sensor fusion across multiple sensing modalities. This is a highly visible leadership role reporting into the Head of Hardware and working closely with the CEO and CTO. Key Requirements 10+ years of sensor or wearable hardware development experience. Deep expertise with PPG sensor systems (highest-priority skill set). Experience owning a sensing system from architecture through product launch. Strong analog front-end design experience. Experience with sensor selection, validation, calibration, characterization, and BOM ownership. Experience with heart rate and HRV algorithms in real-world wearable environments. Experience integrating multiple sensor modalities including optical, inertial, temperature, and environmental sensing. Strong cross-functional experience partnering with EE, Firmware, Mechanical Engineering, and Product Design teams. Comfortable working hands-on in the lab and collaborating with overseas CMs. Preferred Background Sensor Systems Architect experience. SpO2, ECG, EDA, EMG, or additional health-sensing experience. Sensor fusion and multimodal sensing expertise. Human physiology or biomechanics knowledge. Consumer wearable startup or founding engineer experience. Experience leading sensor teams and subsystem development.
