Signal Processing Engineer

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)
• Design studies to ensure millisecond-level synchronization between video streams and reference sensors
• Integrate with the computer vision pipeline using C++
• Architect cloud-based QA and automated verification systems for algorithm validation
• Prototype algorithms in Python and C++ before production deployment

Requirements

• Master's degree or PhD in Electrical Engineering, Biomedical Engineering, or a related field
• 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 and C++
• Experience with spectral analysis, adaptive filtering, and time-domain methods
• 5+ years of industry experience in medical or physiological sensing applications (or equivalent with PhD)

Preferred Qualifications

• Experience with 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
• Familiarity with DevOps practices for reproducible research
• Background in medical devices, regulated environments, or clinical validation studies
