In-person exchanges are invaluable to our work. We’re working a minimum of 4 days a week onsite as part of our commitment to fostering a culture of professional growth and cross-functional collaboration as we work together to engineer the extraordinary.As a Sr. Software Engineer – Signals & Algorithm Interfaces (Python/C++) you will own the production interfaces between the Affera Signals & Algorithms team's work and the rest of the Prism Mapping system. A typical week mixes collaborating with algorithm developers to bring a new algorithm into production, optimizing it for the latency, memory, and determinism the live system demands, designing the data paths that feed it in real time, and partnering with visualization and UI engineers to ensure algorithm outputs are displayed accurately on the map and in the application. You'll write algorithm code yourself when the work calls for it. You'll make architectural decisions about buffering, threading, and data contracts; mentor newer engineers on signal-domain debugging; and set the standard for how we ship algorithm-adjacent code in a regulated environment. About the Affera Prism Mapping System The Affera Prism Mapping System is an advanced electrophysiology mapping platform used by physicians to diagnose and guide the treatment of cardiac arrhythmias. It captures and processes signals from inside the beating heart, builds detailed real-time three-dimensional maps of cardiac anatomy and electrical activity, and presents that information to clinicians and mapping specialists during live procedures. Engineers on this team build the software that makes that possible — from the runtime and data pipelines that move signals in milliseconds, to the algorithms that turn raw signals into clinically meaningful information, to the visualization and UI surfaces clinicians rely on in the lab.
