You will play a key role in building backend services and AI-driven workflows that support urgent and non-urgent care interactions between patients and providers. In parallel, you will actively use modern AI tools to accelerate software development, improve code quality, support design exploration, and maintain high-quality technical documentation. This role is ideal for an engineer who enjoys working across system design, implementation, and mentorship, and who is excited about applying AI in practical, production-grade healthcare solutions.
