Machine Learning Engineering Manager - Voice Model - AI Teams (x/f/m)

We are looking for a Manager to join the Voice Model ASR/STT(Automatic Speech Recognition/Speech-to-text) engineering team in AI & Clinical Products.

As an Machine Learning Manager, your mission will be to lead the team delivering the ASR backbone that powers our AI products, helping health professionals save time on documentation and focus more on patient care. You will be working in a feature team developing the speech recognition technology for Doctolib's AI-powered solutions including Consultation Assistant and Phone Assistant.

Your responsibilities include but are not limited to:

• Own the ASR roadmap end-to-end: model design, training, evaluation, and product integration for medical-grade speech recognition
• Lead and mentor a team of Speech-to-text experts; foster a high bar for research rigor, code quality, and operational excellence
• Partner with MLOps to ensure training and inference pipelines are scalable, cost-efficient, and reliable in production
• Collaborate with product, design, and clinical teams to translate user needs into measurable technical objectives
• Drive continuous improvements to WER, medical term error rate, latency, diarization, domain adaptation, and multilingual performance

To address these challenges, we are modularizing our platform run in a distributed architecture through reusable components.
• Our stack is composed of Rails, TypeScript, Java, Python, Kotlin, Swift, and React Native.
• 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!
