Artificial Intelligence Microsoft Azure Python (Programming Language) Machine Learning Large Language Models Prompt Engineering AI Platforms

Job description

  • Develop and optimise prompts, structured outputs, validation logic and post-processing components.
  • Compare LLMs, multimodal models, OCR and deterministic approaches to select the right solution for each use case.
  • Build representative datasets, define ground truth and establish robust evaluation metrics.
  • Run experiments, analyse failure patterns and iterate to improve accuracy and reliability.
  • Create reproducible Python workflows and contribute reusable components for extraction, validation and data prep.
  • Collaborate with Product, AI Engineering and business teams to translate requirements into measurable data science problems.
  • Communicate findings clearly to both technical and non-technical audiences.

Requirements

  • 3+ years in data science, machine learning or applied AI.
  • Hands-on experience with LLMs, prompt engineering and experimentation.
  • Strong NLP/ML fundamentals and the judgement to know when classical methods outperform LLMs.
  • Solid statistics - enough to judge whether a performance change is real.
  • Experience with unstructured or semi-structured documents.
  • Python skills that make your work reproducible and easy for engineers to productionise.
  • Ability to explain technical trade-offs clearly.
  • Comfortable diving into business domains to understand what “correct extraction” actually means.
