About Source Meridian
Source Meridian is a leading software development company dedicated to addressing the most pressing challenges in healthcare. Our focus includes cutting-edge technologies in healthcare and life sciences, such as artificial intelligence and healthcare interoperability.
About the Role
We are seeking a talented AI Engineer with practical experience in creating production-ready AI systems utilizing large language models (LLMs), agentic frameworks, and contemporary data infrastructures. The successful candidate will design, develop, and implement intelligent applications that utilize LLM orchestration, retrieval-augmented generation (RAG), and memory-managed architectures.
What You’ll Do
• Design and implement agentic workflows using LangGraph and LangChain, inclusive of multi-step reasoning, tool usage, and human-in-the-loop patterns.
• Integrate LLMs (OpenAI, Anthropic, Google Vertex AI, open-source models) via REST APIs and SDKs into scalable backend services.
• Develop and maintain RESTful APIs (FastAPI) to deliver AI-powered functionalities to front-end applications and external consumers.
• Architect and manage vector database solutions (Milvus) for semantic search and RAG.
• Create context engineering strategies, including prompt templates, dynamic context window management, token optimization, and context compression techniques.
• Implement short-term memory (conversational buffers, sliding windows, summary memory) and long-term memory (persistent vector stores, knowledge graphs, user profile stores) using MongoDB and vector databases.
