Help us build a focused, sharp system that turns peer-reviewed nutrition literature into transparent, evidence-based recommendations. You'll implement the Extract, Transform Load (ETL) pipeline from Open Alex, fine-tune and wire up transformer models for relation extraction, and ship a production‑grade recommendation/generative layer backed by a provenance‑rich knowledge graph.

• Stand up and own a Pub Med or Open Alex ETL that ingests open-access articles, normalizes metadata, and keeps our corpus fresh.
• Use and/or fine‑tune transformer models (e.g., BERT variants) to extract semantic triples (like: (ingredient)-[biolink:]->(health condition)); build evaluation and error‑analysis loops.
• Implement a ranking layer that blends evidence strength (study design, sample size, effect size) with model confidence.
• Build the recommendation/generative service that balances constraints (evidence score, compatibility, regulatory limits) and exposes a clean API.
• Construct/maintain a knowledge graph that links every recommendation back to source papers (full provenance) and supports plain‑language evidence summaries.
• Collaborate tightly with PI and domain scientists; deliver milestones on a fast, 12‑month pilot timeline.

• Python 3.x; modern NLP/ML (PyTorch or Tensor Flow, Hugging Face, scikit-learn); data/ETL tooling (pandas, spaCy, Pydantic, Airflow/Prefect).
• APIs/services: RESTful design, auth, pagination, retries, structured logging, unit/integration tests, CI.
• Storage/search:
  Postgres + vector/embedding store; graph DB experience welcome.
• Dev Ops basics: containers, reproducible envs, simple local deploys, secrets management.

• Deep NLP experience (relation extraction, weak supervision, prompt/adapter tuning).
• Semantic KGs (RDF/OWL, Neo4j/graph tooling), ontology work, and/or the Biolink Model
  .
• Experience with biomedical text corpora and literature mining.
• You’ve shipped scrappy, reliable research‑to‑prod systems before.

• 3+ years professional Python and ML/NLP engineering, or equivalent portfolio.
• Strong engineering hygiene (tests, docs, code review) and product sense.
• Clear, direct communication in a remote team.
• Bonus: prior work at the intersection of ML + biosciences/clinical data.

• Fully remote (U.S.); office space available at Penn State for hybrid/in‑person if preferred.
• Part‑time at $57/hour
  , 20 hours/week
  , 50 weeks
  . Continuation beyond 50 weeks depends on renewal/next‑round funding.
