Responsibilities
- Implement specialized pharmacovigilance agents using system prompts, model configuration, tool-use definitions, and defined agent boundaries.
- Build and iterate prompt chains for source parsing, field extraction, MedDRA coding suggestions, causality assessment, narrative drafting, and E2B(R3) generation.
- Develop deterministic ICH E2B validation, MedDRA hierarchy verification, and regulatory logic constraints alongside LLM outputs.
- Create evaluation datasets, annotated ground-truth cases, edge-case libraries, and regression test suites with pharmacovigilance experts.
- Develop and maintain Model Context Protocol servers and secure integrations with enterprise applications, APIs, databases, and services.
- Run accuracy benchmarks, analyze failure modes, and improve prompts and agent configurations against defined thresholds.
- Implement quality-control cross-verification using separate Claude instances, comparison algorithms, and confidence scoring.
- Build human-in-the-loop reviewer interfaces and feedback pipelines for accept, modify, and reject decisions.
Requirements
- At least 3 years of software engineering experience, including at least 1 year building applications that use LLM APIs.
- Production proficiency in Python.
- Experience building and evaluating NLP or LLM-based systems with measurable quality metrics.
- Experience with prompt engineering, including system prompts, few-shot examples, chain-of-thought patterns, and structured output formats.
- Hands-on experience with LLM orchestration frameworks such as LangChain, LangGraph, or similar tools.
- Experience with evaluation pipelines using precision/recall, confusion matrices, and threshold tuning.
- Comfort with AWS services including S3, Lambda, and IAM; AWS Bedrock experience is preferred.
- Strong written communication for documenting prompt decisions, evaluation results, and agent behavior specifications.
- Bachelor's degree in computer science or a related field, or equivalent professional experience.
- Preferred experience includes clinical NLP, medical coding or adverse-event extraction, MedDRA or ICD-10, OCR and document processing, and pharma, biotech, CRO, or healthcare IT.
Benefits
- Flexible work environment and space to do one's best work.
- Growth and continuous learning opportunities in large language models, prompt engineering, and healthcare AI.
- Opportunity to influence clinical research safety systems and work with cross-functional domain and platform teams.
