• Experience building software in regulated environments (healthcare, medical devices, fintech, etc.)
• Familiarity with AWS, Docker, and Kubernetes
• Experience with event-driven architectures, background jobs, or message queues
• Prior experience helping scale an early-stage or growth-stage product
• Exposure to probabilistic systems, Bayesian reasoning, or clinical decision support platforms
