• 1+ years of experience developing agentic AI systems, including multi-step reasoning workflows, task orchestration, or tool-calling agents
• Hands-on experience with modern AI orchestration frameworks (e.g., LangChain, LangGraph, LlamaIndex, Semantic Kernel, AutoGen, CrewAI, or cloud-native AI services)
• Experience deploying scalable AI solutions within cloud environments (e.g., Azure, AWS, GCP) using microservices, containers, or serverless architectures

Preferred Qualifications:

• Master"s degree in Computer Science, Data Science, Engineering, Artificial Intelligence, or a related field
• Experience developing AI solutions specifically for healthcare domains, such as care management, clinical documentation, utilization management, or clinical applications
• Experience configuring and integrating vector databases or search platforms (e.g., Azure AI Search, Pinecone, Weaviate, FAISS, Chroma, OpenSearch, or Elasticsearch)
• Experience with traditional ML frameworks (e.g., PyTorch, TensorFlow, scikit-learn) combined with LLM-based workflows
• Experience with LLM evaluation frameworks, prompt versioning, synthetic data generation, and LLMOps monitoring tools
• Solid understanding of security design in regulated environments, including role-based access control, encryption, and safe handling of PII/PHI
