• Expert-level MLOps — MLflow, Kubeflow, Vertex AI, SageMaker, or equivalent.
• Proven track record leading ML projects from zero to production.
• Experience mentoring senior engineers or tech-leading ML teams.
• Strong architectural instinct and communication skills.

Desirable

• Healthcare ML experience (EHR, FHIR, clinical NLP, medical imaging).
• Expertise with LLMs, foundation models, or RAG systems in a regulated setting.
• Experience with clinical safety standards and medical-device regulation.
• Publications in top ML / clinical informatics venues.
