Senior Security Engineer

About Sirona Medical At Sirona Medical , we’re building software that enables physicians to work as fast as they can think. Each year in the U.S., billions of patient images are captured—and nearly all of them are reviewed and diagnosed by radiologists. These specialists are the central hub of diagnostic medicine: over 80% of all healthcare data flows through radiology IT systems . Yet despite their pivotal role, radiologists are overburdened by outdated, fragmented software which limits their efficiency and ultimately the quality and efficiency of care that health systems can provide patients. That’s where Sirona comes in. We’re a San Francisco-based, cloud-native software company with employees around the world. Our deep understanding of both the practice and business of radiology has allowed us to build RadOS —a unified, AI-powered operating system powering the entire radiology workflows. How Sirona Solves the Problem Sirona is uniquely positioned to transform the way radiology is practiced . We're delivering the organizational shift that both individual radiologists and entire practices urgently need: • A unified , intuitive, and platform-agnostic solution • A streamlined workspace that makes every part of the radiologist’s workflow faster and easier • The freedom to read from anywhere, for anyone By cutting clicks, optimizing diagnostic time, and unlocking efficiencies that extend far beyond the reading room into all care settings , Sirona empowers radiologists—and in doing so, we help the entire healthcare system move faster, smarter, and with greater impact on patient outcomes.
