Systems Software Engineer (Embedded & Hardware Integration)

Company Description

iSono Health has developed the world’s first wearable, point-of-care, AI-driven platform with an innovative 3D quantitative ultrasound device designed for early breast cancer detection and monitoring. Our patented technology enables automated 3D scanning of the whole breast within just two minutes per breast without requiring a skilled sonographer. Images are transferred securely to the cloud, allowing radiologists to view results remotely via a simple URL-based viewer. By leveraging advanced machine learning algorithms, our platform identifies abnormal masses, expanding access to point-of-care diagnostics and monitoring across radiology centers, mobile clinics, and beyond. The platform offers a safe, painless, and fast diagnostic experience with actionable AI-driven feedback.

We have created a new category of data-driven infrastructure for early cancer detection, no sonographer required, and built for longitudinal insights. Our mission is to make personalized whole breast imaging accessible to all women worldwide, so no woman dies because her breast cancer goes undetected.
