Join us in shaping the future of healthcare through AI excellence.

We are seeking a Lead Data Scientist to define and drive the new frontier of AI-Human interaction. You will lead the design of adaptive, human-aware AI systems that learn form, respond to, and collaborate with humans in real-world environments. This role blends cutting-edge research, robust experimentation, and product-focused execution to improve user trust, alignment, usability, and agent cooperation across intelligent interfaces.

Key Responsibilities 

• Develop and own ML pipelines for evaluating and improving human-AI interaction across modalities (text, speech, UI/UX feedback, behavioral signals)

• Design adaptive models for intent recognition, dialog state tracking, preference learning, and multi-turn personalization

• Lead human-in-the-loop data collection strategies and feedback integration to fine-tune agent behaviors

• Partner with UX, engineering, and safety teams to embed explainability, user control, and alignment into AI systems

• Develop and monitor human-centered evaluation metrics (e.g., helpfulness, latency, trust calibration, long-term engagement)

• Construct causal inference and A/B testing to assess impact of interaction strategies on behavior and outcomes

• Mentor a team of data scientists and collaborate with AI researchers and product leaders on foundational interaction improvements

• Experience in creating reports, projections, models, and presentations to executives

Technical skills

• Proficiency in SQL, Python, and data analysis/data mining tools.

• Experience with machine learning frameworks like Pytorch, JAX, LangChain, or LangGraph

• Experience with high performance, large-scale ML systems

• Experience with language modeling with transformers

• Experience designing human-centered evaluation protocols, metrics, and pipelines

• Experience with +5 years of experience in applied ML, with at least 3+ in conversational AI, human-in-the-loop systems, or agent UX optimization

• Experience with large-scale ETL
