We are laser focused on specific technologies in the healthcare and life science industries: Healthcare technology, artificial intelligence, and healthcare interoperability.
The Role
AI Engineer with hands-on experience in building production-grade artificial intelligence systems using large language models (LLMs), agentic frameworks, and modern data infrastructure. The adecuado candidate designs, develops, and deploys intelligent applications that leverage LLM orchestration, retrieval-augmented generation (RAG), and memory-managed architectures.
What You’ll Do

- Integrate LLMs (OpenAI, Anthropic, Google Vertex AI, open-source models)



via REST APIs and SDKs into scalable backend services.
- Build and maintain RESTful APIs (FastAPI) to serve AI-powered functionality to frontends and external consumers.
- Architect and manage vector database solutions (Milvus) for semantic search and retrieval-augmented generation (RAG).
- Design 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.
- Store and manage structured and unstructured data in MongoDB, designing schemas that support conversation history, user state, and agent checkpoints.
- Evaluate and improve the quality of LLM responses through prompt engineering, few-shot examples, guardrails, and automated evaluation pipeline
