Signal Processing Engineer developing clinical-grade vital-sign algorithms from video for Norbert’s autonomous healthcare robots. Validating physiological measurements against clinical reference devices.
Responsibilities
Design and implement signal processing algorithms for extracting vital signs from video-based sensors (rPPG, rBP)
Develop real-time filtering, denoising, and feature extraction methods to achieve clinical-grade accuracy
Build validation pipelines comparing video-based measurements against clinical reference devices (ECG, PPG, BP monitors)
Help design studies ensuring millisecond-level synchronization between video streams and reference sensors for accurate ground truth
Integrate with the computer vision pipeline in C++ to leverage multi-modal signal enhancement techniques
Architect cloud-based QA and automated verification systems for reproducible algorithm validation
Prototype algorithms in Python and C++ before deploying them on the production system
Requirements
Master's degree in Electrical Engineering, Biomedical Engineering, or related field (or PhD)
Strong fundamentals in digital signal processing, statistical methods, and real-time systems
Deep expertise in physiological signal processing (Radar, PPG, ECG, respiration, blood pressure)
Experience processing low-frequency physiological signals with challenging SNR characteristics
Proficiency in both Python (prototyping) and C++ (production integration)
Experience with spectral analysis, adaptive filtering, and time-domain methods for real-time applications
Ability to work independently, solve complex problems, and drive projects to completion
5+ years industry experience developing signal processing algorithms for medical or physiological sensing applications (or equivalent with PhD)
Experience with contact-based and contactless vital sign measurement technologies, especially radar
Background working with medical-grade measurement devices and clinical reference standards
Experience with embedded signal processing (ARM, edge devices)
Knowledge of motion artifact removal and noise reduction in challenging environments
Familiarity with DevOps practices for reproducible research (experiment tracking, data versioning)
Background in medical devices, regulated environments, or clinical validation studies
