Responsibilities
Modern cloud architecture, built from scratch: We have no legacy systems to untangle. We’re designing a modern cloud-native platform with Elixir at its core
Develop a radically better access control system for clinical data: Create a modern access control system with fine-grained permissions that respects clinical data structure and patient data ownership, while enabling population-level insights for better public health
Keep hospitals online 24/7 - no matter what: Design and ship infrastructure that can handle rolling deployments, failover, and real-time data sync in environments where downtime isn’t an inconvenience - it’s a risk to patient care
Bridge the gap between software and hardware: Architect a next-generation integration engine to connect ventilators, bedside monitors, imaging equipment, lab equipment, and more - reliably and in real time
Push hospital workflows into the modern age: Rethink and rewire how data moves between nurses, doctors, and administrators - and turn confusing, click-heavy workflows into fast, intuitive experiences
