We are looking for a Senior Staff Machine Learning Engineer to join the Clinical team in the AI and Machine Learning Department. You'll lead the technical direction of AI systems that enhance clinical decision-making and patient care. You'll tackle the hardest problems in healthcare AI, from building voice-powered consultation assistants to establishing LLM evaluation frameworks that ensure clinical safety and efficacy. This role combines deep R&D with strategic technical leadership, shaping how Doctolib deploys AI in regulated healthcare environments.
Your responsibilities include but are not limited to:
Technical Strategy & Architecture
- Own the long-term technical roadmap for clinical ML systems, from model architecture selection to production deployment patterns
- Drive strategic build vs. buy decisions, balancing custom development with foundation model APIs
- Define standards for safe rollout in healthcare contexts: shadow testing, staged deployment, and human-in-the-loop workflows
End-to-End ML Delivery
- Lead design and implementation of LLM-powered clinical agents (consultation summarization, clinical coding, evidence-grounded recommendations)
- Establish rigorous evaluation frameworks using real-world clinical datasets, ensuring outputs meet clinical accuracy and safety standards
- Build production infrastructure: model and prompt versioning, guardrails, uncertainty quantification, cost optimization, and observability
