About Job Overview: We are seeking a highly analytical and detail-oriented Healthcare Prompt Engineer to design, evaluate, and optimize clinical prompt frameworks that power high-quality, specialty-appropriate AI-generated clinical documentation. This role bridges clinical workflows, LLM prompt engineering, and experimentation frameworks to ensure scalable, reliable, and release-ready prompt configurations across multiple specialties. Roles and Responsibilities: - Design and optimize clinical prompt templates to generate consistent, specialty-appropriate clinical documentation from transcripts. - Conduct structured prompt experiments (e.g., A/B testing, targeted worksets) to evaluate performance, identify failure modes, and implement systematic improvements. - Translate experimental findings into production-ready prompt configurations with measurable quality gains. - Operationalize prompt updates using Git and Azure DevOps (ADO): manage work items, track bugs, participate in pull request workflows, and maintain version-controlled prompt artifacts. - Develop and maintain Python/Linux research scripts to run batch evaluations, in-lab experiments, and data processing pipelines supporting prompt development. - Incorporate feedback from customers and cross-functional stakeholders into structured rollout plans spanning multiple clinical specialties. - Define monitoring strategies and evaluation criteria to ensure safe, accurate, and scalable deployment of prompt updates. Qualifications: - Proven experience developing and refining LLM prompts, including instruction design, templating, few-shot patterns, and iterative optimization, ideally in semi-structured clinical text generation environments. - Strong proficiency in Python and Linux for building experimentation scripts and evaluation pipelines. - Experience with version control systems (Git/GitHub) and engineering workflows, including Azure DevOps (ADO) for work tracking and release coordination. - Strong analytical and problem-solving skills, with the ability to define evaluation metrics, review outputs systematically, and prioritize fixes based on impact and risk. - Familiarity with clinical documentation workflows and healthcare data environments. - Excellent communication skills with demonstrated cross-functional collaboration ability. - Fluency in English and Dutch.
