Responsabilités

• Own the full technical stack - from core backend services to user-facing interfaces - and help deploy reliable AI agents in hospitals.

• Ship and iterate on LLM-powered agents that automate complex end-to-end workflows.
• Work alongside the CTO to make the right architecture decisions, balancing speed and long-term scalability.
• Build interfaces that doctors and administrative operators actually want to use - understanding their pain points, not just closing tickets.
