Axle is seeking a Senior Data Scientist, Agentic AI Systems to join our vibrant team supporting rare disease research at the National Institutes of Health (NIH). This is a Remote position within the United States.

Roughly 25 to 30 million people in the United States live with a rare disease. There are somewhere between 7,000 and 10,000 distinct rare conditions, and the large majority have no FDA-approved treatment.

Research on these conditions keeps running into the same obstacles. Published evidence for any one disease is thin and scattered across sources. The same clinical finding gets written down a dozen different ways depending on who recorded it. And the people with the most at stake, patients and their families, are usually the least equipped to read the specialist literature written about their own condition.

Large language models are well suited to this class of problem, and the research programs we support are investing in applying them carefully. In this role you will build the conversational AI systems that sit between a person and the research infrastructure. These are multi-turn workflows that ask sensible follow-up questions in plain language, capture the answers as validated structured data, and hand that structure off to the searches and analyses doing the scientific work. The emphasis is on systems people can rely on, which in practice means confirming every interpretation before it is saved and logging every automated decision so that it can be reviewed later.

This is a senior individual contributor position. You will own major components from design through deployment, work directly with NIH program staff, clinical geneticists, and rare disease information specialists, and help set the engineering standards for how AI gets applied on this team.

Core Responsibilities

Build agentic AI systems for rare disease research workflows. This includes the conversation logic, the rules that decide when enough information has been gathered, and the confirmation steps that catch a misreading before it reaches anything downstream.

Model outputs in Pydantic and use structured output and tool calling, so that every field a model produces is typed, validated, and traceable back to its source.

Write, version, and regression test the prompts behind clinical and scientific reasoning tasks. Prompts and output schemas are treated as code here, with tests to match.

Build evaluation for tasks that have no single right answer. Golden sets, offline regression suites, and model-based graders all have a place, and the results should be good enough to decide what ships.

Keep multi-step LLM workflows responsive under load. This covers async design, concurrency limits, streaming partial results to the client, and timeout and failure handling that holds up in production.

Log what the system does and why. Request identifiers, latency, errors, and the reasoning behind each automated choice all need to be capt...
