We are looking for a Machine Learning Operation Intern to join the Machine Learning Platform team of Doctolib.

Doctolib operates state-of-the-art medical speech recognition models that power products such as our Consultation Assistant, Medical Dictation, and Telephone Assistant. These models run in both batch and real-time streaming modes. While the batch infrastructure is already robust and widely deployed, the streaming stack is less mature and needs to evolve into a scalable, production-grade system. As a Machine Learning Operation Intern, your mission will be to design and implement the next generation of our real-time speech infrastructure.

Your responsibilities include but are not limited to:

• Conduct standardization initiatives across several projects leveraging speech technologies
• Lead MLOps initiatives for real‑time speech AI
• Design and implement distributed, fault‑tolerant streaming inference components
• Set up model serving, autoscaling and rollout strategies
• Build a secure, high-performance system that can support large-scale usage
• Benchmark throughput, reliability and fault tolerance

We leverage AI ethically across our products to empower patients and health professionals. Discover our AI vision here and learn about our first AI hackathon here!
