Position Overview

NGRF is seeking a researcher to join the LLM Lab and contribute to NGRF's scientific discovery platform. This role combines original research in scientific integrity with hands-on development of NLP and AI capabilities on a large-scale biomedical data platform.

The researcher will work with a multi-terabyte curated literature database, develop and evaluate NLP models, build retrieval-augmented generation (RAG) pipelines, and contribute to a federated knowledge graph that models scientific claims and evidence relationships. The role spans research and engineering — publishing peer-reviewed findings while building the models and pipelines that power NGRF's platform.

Key Responsibilities

• Scientific integrity research : Design and execute large-scale computational analyses of scientific publishing practices across the biomedical literature. Publish findings in peer-reviewed venues (e.g., Scientometrics, JASIST, Quantitative Science Studies).

• NLP model development: Develop and validate models for semantic analysis of scientific text — including claim extraction, relevance scoring, and relationship detection. Build on existing RAG infrastructure and vector search capabilities.

• Big data and pipeline engineering: Work with a multi-terabyte literature database and external APIs (PubMed, CrossRef, OpenAlex) to build scalable data processing and analysis pipelines. Integrate structured and unstructured data sources into reproducible workflows.

• Collaboration and outreach: Work with external partners in the research integrity community. Present findings at conferences and contribute to NGRF's visibility in the scientific integrity space.

Required Qualifications

• PhD in natural language processing, computational linguistics, computer science, information science, or a related field

• Publication record in NLP, text mining, or computational approaches to scientific literature

• Strong programming skills in Python with experience in modern ML/NLP frameworks (e.g., PyTorch, Hugging Face Transformers)

• Experience working with large text corpora and large-scale datasets

• Familiarity with vector databases, embeddings, semantic search, and retrieval-augmented generation (RAG)

• Experience with knowledge graphs, ontology design, or graph databases

• Demonstrated ability to design and execute independent research projects

• Strong written and oral communication skills

Preferred Qualifications

• Background in scientometrics, bibliometrics, or research integrity

• Experience with scientific publishing APIs and metadata (DOIs, PubMed, CrossRef, OpenAlex)

• Familiarity with claim extraction, relation extraction, or scientific argument mining

• Proficiency with Git, GitHub, and collaborative software development workflows

• Experience with Linux/Unix environments and command-line tools

• Familiarity with containerization (Docker) and CI/CD pipelines

• Experience with AI-assisted development tools (e.g., Claude Code, GitHub Copilot)

• Experience deploying NLP models in production or near-production settings

• Familiarity with Kubernetes, infrastructure-as-code, or cloud platforms (AWS)

• Experience with SQL databases (PostgreSQL) and data modeling

• Track record of interdisciplinary collaboration

Compensation

The prospective salary range for this position is $80,000–$92,000 annually.
