Employment type: full-time


Responsibilities:


  • Design, test, and optimize prompts for generative AI tools (e.g., ChatGPT, Claude, Gemini, LLaMA) to achieve high-quality, reliable outputs

  • Apply advanced prompting techniques, including few-shot learning, chain-of-thought reasoning, role-based prompting, and prompt chaining

  • Develop and manage system prompts and user prompts, ensuring proper interaction and alignment with intended use cases

  • Evaluate LLM outputs for accuracy, consistency, hallucinations, and unsupported claims, with strong attention to detail

  • Define, monitor, and refine KPIs for LLM output quality, usability, and reliability

  • Optimize prompts with awareness of token usage, cost efficiency, and performance trade-offs

  • Conduct iterative experimentation, quality evaluation, and content testing to continuously improve prompt performance

  • Break down complex documents into reusable prompt components, templates, and instructions

  • Collaborate with subject matter experts (SMEs) to translate business, clinical, or regulatory requirements into effective prompt logic


Requirements:


  • Hands-on experience with generative AI tools and prompt design best practices

  • Strong understanding of LLM parameters (e.g., temperature, top_p, max_tokens, frequency penalty) and their impact on model behavior

  • Knowledge of context window limitations and strategies for effective context management

  • Experience with chunking strategies and metadata tagging for content retrieval

  • Strong analytical skills, including the ability to identify inconsistencies, missing information, and unsupported claims in AI-generated content

  • Experience in structured writing, technical writing, or documentation, preferably within regulated industries (e.g., pharma, biotech, medical devices)

  • Comfort reading and interpreting R&D or clinical documentation, with a solid understanding of standard document structures

  • Ability to understand complex documentation and transform it into clear, reusable prompt instructions

  • Excellent communication skills and ability to work cross-functionally with technical and non-technical stakeholders

  • Full professional proficiency in both Polish and English

  • Experience in clinical operations or medical writing


Nice to Have:


  • Familiarity with CTD structure, CSR guidelines (ICH E3), clinical protocols, and SAP structure

  • Basic understanding of Retrieval-Augmented Generation (RAG) pipelines

  • Familiarity with Python, JSON, or YAML to collaborate effectively with LLM developers

  • General understanding of AI concepts, limitations, and failure modes
