✓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 captured, so that staff can review an AI-assisted result instead of taking it on faith.

✓Work out what researchers, clinicians, and patient communities need, and turn it into data models and system behavior.

✓Write the work up. You will contribute to manuscripts, conference abstracts, and posters with NIH investigators, and you will be credited as an author on work you helped produce.

✓Bachelor’s degree in Data Science, Computer Science, Bioinformatics, Biomedical Informatics, or a related field. An advanced degree is preferred. We will consider equivalent professional experience in place of a degree.

✓At least 5 years building and operating production software or data systems. At least 2 of those years should involve shipping LLM-powered applications (agents, retrieval, or evaluation) that people depend on. We weigh depth in agentic workflow engineering more heavily than total years.

✓Experience with structured output and tool or function calling, meaning you have constrained a model to a typed schema and validated what came back.

✓Experience evaluating systems that have no single right answer, using golden sets, offline regression suites, or model-based graders to decide whether a change was an improvement.

✓Ability to own a service end to end, from schema design through deployment and operation.

✓Ability to obtain and maintain a Public Trust Security clearance.

✓Python, with FastAPI, Pydantic, and pytest.

✓LLM application engineering: provider APIs and gateways, prompt and context design, structured generation, tool use, and tracing.

✓PostgreSQL, including work with embeddings or vector search alongside relational data.

✓Asynchronous and concurrent Python, plus streaming results to a client.

✓Containers and Kubernetes, enough to ship, debug, and operate a service on infrastructure you do not administer.

✓Git-based collaboration and CI/CD in a shared codebase.

✓A typed agent framework such as Pydantic AI, LangGraph, or the OpenAI or Anthropic agent SDKs, and MCP for tool integration.

✓LLM tracing and evaluation tooling such as Langfuse, LangSmith, Arize Phoenix, or Braintrust.

✓Serving open-weight models in production with Ollama or vLLM behind a gateway such as LiteLLM.

✓Biomedical ontologies and controlled vocabularies, including MONDO, HPO, UMLS, MeSH, and other OBO Foundry resources, along with comfort working through term hierarchies, synonyms, and cross references.

✓Background in rare disease, clinical genetics, or translational research.

✓Experience working alongside clinicians, curators, or patient advocacy organizations, and translating their vocabulary into a data model that holds up.

✓Published or presented work that explains your engineering to people who did not build it. Peer-reviewed papers, conference talks, preprints, technical blog posts, and public open source contributions all count.

✓Prior or current NIH experience.
