Description

  • Collaborate with domain experts to identify business needs and translate them into clear, effective prompts for LLMs.
  • Develop, test, and iterate prompts for multiple use cases to ensure high accuracy and relevance of generated outputs.
  • Detect, diagnose, and resolve prompt-related issues and errors (e.g., hallucinations, prompt leakage, edge cases).
  • Design multi-step prompt workflows, including agentic patterns, tool calling, and retrieval-augmented generation (RAG) solutions.
  • Work closely with software developers to integrate LLM solutions into product pipelines and applications.
  • Define and maintain quantitative and qualitative evaluation metrics for LLM outputs (accuracy, relevance, safety, latency, cost).
  • Contribute to building a scalable prompt engineering framework for reuse and cross-business knowledge sharing.
  • Collect and analyze user feedback to continuously improve prompt effectiveness.
  • Monitor LLM technology trends and participate in strategic selection of tools and platforms.
  • Document prompt engineering processes, best practices, and implementation results to create a structured knowledge base.

Requirements

  • Bachelor’s degree in Computer Science, Engineering, Mathematics or a related field.
  • At least 4 years of experience in AI/ML, NLP or applied systems built on LLMs.
  • Practical experience with LLM systems and techniques, including RAG, embeddings, function/tool calling, and orchestration frameworks.
  • Experience with models and platforms such as OpenAI GPT and Hugging Face.
  • Experience evaluating LLM outputs and analyzing common failure modes (hallucinations, prompt leakage, edge cases).
  • Proficient in Python or other programming languages used in AI/ML development.
  • Strong analytical skills and attention to detail.
  • Excellent communication skills with the ability to explain technical concepts to non-technical stakeholders.
  • Ability to work collaboratively in a team and adapt to changing project requirements.
  • Upper-Intermediate English proficiency or higher.
  • Available to work as a freelance, remote contractor based in Ukraine.
