Machine Learning Engineer - Optical Blood Pressure Estimation

About Hilo by Aktiia

High blood pressure is the world’s most common disease, causing 18M deaths each year. At Hilo by Aktiia , our vision is a world where no lives are lost or damaged from the effects of high blood pressure. Our mission is to make this a reality by developing tech to help people control their blood pressure.

We are a venture-backed scale-up company, having raised over $96M from investors in Europe and the United States. Our technology - rooted in 18 years of research at the Swiss Center for Electronics and Microtechnology (CSEM) - is the world’s only medically accurate, continuous blood pressure monitor that is cuffless in daily life in the consumer space. Validated through extensive clinical trials and CE Marked as a Class IIa medical device, our solution is now available in 12 countries. We are a hybrid / remote-first company, with Headquarters in Neuchâtel, Switzerland, united by our passion for impact and innovation.

Role Overview

We're currently looking for a Machine Learning Engineer - Optical Blood Pressure Estimation to join our team.

Core Responsibilities

• Optical Signal Modelling & ML Development : Design, develop, and refine machine-learning models that estimate blood pressure from optical data (PPG / rPPG, RGB video) captured via smartphone cameras
• Signal Processing & Feature Extraction : Work hands-on with camera-derived biomedical signals, applying optical and physiological signal-processing methods to build robust input pipelines
• Model Improvement & Iterative Experimentation : Analyze model behaviour, run systematic experiments, and drive continuous iteration to enhance accuracy, robustness, and generalization across diverse conditions
• Production Readiness & Deployment Support : Prepare ML models for deployment on mobile devices and cloud systems, collaborating with engineering to ensure smooth integration and medical-grade reliability
• End-to-End Ownership of the Modelling Pipeline : Take full responsibility for the ML workflow—from data preparation to modelling, validation, documentation, refinement, and performance tracking
• Cross-Functional Collaboration : Work closely with colleagues in AI / Data Science, engineering, physiology, and software to ensure solutions are technically sound and aligned with product needs
• Leading Role in Optical BP Estimation : Advance a novel ML technology application : shape, optimize, and mature an emerging ML capability central to the Hilo Lens product line

Requirements

Background & Experience

We’re looking for a hands-on builder who has developed, iterated, and optimized machine-learning models for real-world signals — someone who thrives where algorithms meet real users and who’s excited to drive camera-based blood-pressure estimation in digital health.
