## About the role

As an AI Engineer, you will be at the forefront of bridging the gap between massive, decentralized biomedical datasets and life-saving insights. You won't just be building "standard" models; you will be co-architecting AI that functions within a federated ecosystem, where privacy and security are paramount.

## What they're looking for

- Design and implement autonomous AI agents using frameworks like LangGraph, CrewAI, or AutoGen to handle complex, multi-step scientific queries
- Develop sophisticated reasoning loops (e.g., ReAct, Plan-and-Execute) that allow agents to decompose high-level research goals into actionable sub-tasks
- Build and optimize Advanced RAG (Retrieval-Augmented Generation) pipelines that integrate structured clinical data and unstructured scientific literature
- Create and maintain "tools" for AI agents, enabling them to safely interface with Lifebit’s federated APIs, SQL databases, and bioinformatic execution engines
- Implement secure, sandboxed code-interpreter capabilities, allowing agents to write and execute Python or R code for data visualization and statistical analysis
- Fine-tune LLMs for specific function-calling and tool-use accuracy within the life sciences domain
