Definitive Healthcare Announces Data Scientist, Applied AI Role to Boost Healthcare‑Focused LLM Solutions

Overview

Definitive Healthcare, a data‑analytics firm serving the life‑sciences sector, posted a new opening for a Data Scientist, Applied AI in Iselin, New Jersey. The posting, visible on LinkedIn, outlines a role that blends research‑grade large language model (LLM) work with production‑ready pipelines for healthcare data.

Key Responsibilities

• Develop AI workflows: Build and test LLM, Retrieval‑Augmented Generation (RAG), and tool‑using agent pipelines for defined use cases.
• Evaluate approaches: Compare LLMs, embedding models, and retrieval methods on quality, reliability, latency, and cost, following criteria set by senior staff.
• Maintain evaluation assets: Create benchmark datasets, regression checks, and representative test cases; report findings and limitations.
• Improve retrieval quality: Tune RAG pipelines—including embeddings, retrieval, reranking, and grounding—based on evaluation results.
• Investigate failures: Analyse incorrect answers or workflow breakdowns and implement measurable fixes.
• Support production workflows: Use experimentation, tracing, and observability tools to monitor systems and diagnose performance shifts.
• Collaborate on delivery: Work with engineering, product, and domain partners to clarify requirements, share findings, and deliver practical AI solutions.

Required Experience

• Bachelor’s degree in a quantitative or technical discipline.
• 3+ years of experience in data science, machine learning, or applied AI.
• Hands‑on experience developing applications with LLMs and evaluating their outputs.
• Strong Python programming, data‑analysis, and problem‑solving skills.
• Familiarity with embeddings, semantic search, retrieval, RAG, and evaluation metrics.
• Experience with an agent framework such as PydanticAI, LangGraph, or similar tools.
• Ability to design test cases, interpret results, and flag limitations.
• Knowledge of cloud data/ML platforms, Git, testing, and collaborative development is a plus.
• Prior work with healthcare data, Databricks, or large‑scale deployment is beneficial but not required.

Company Context

Definitive Healthcare describes itself as “obsessed with data,” providing reliable, validated datasets to pharma, biotech, and provider organizations. Recent recognitions include Built In’s *100 Best Places to Work in Boston* (2024‑2025) and a Stevie Bronze Award for Great Employers. The firm emphasizes a culture of accountability, collaboration, and employee‑driven community programs.

Practical Implications

• For candidates: The role offers a chance to apply cutting‑edge LLM research to real‑world healthcare problems without people‑management duties.
• For the industry: Strengthening AI pipelines at a major data provider could accelerate adoption of LLM‑driven analytics in drug discovery and market access.
