Summary: The AI / ML Engineer role focuses on designing and operating production-grade AI services on Azure, emphasizing semantic indexing and vector-based retrieval. The position requires collaboration with various teams to ensure secure and reliable deployment of AI models. The role is primarily remote with occasional on-site visits in Poland, specifically in Krakow or Warsaw. The contract duration is between 6 to 12 months, and the position is suitable for candidates with significant experience in ML/AI solutions.

Key Responsibilities:

  • Build and maintain Azure-based AI components, including vector stores, semantic indexes, and retrieval services
  • Develop embeddings, search strategies, and high-performance ANN workflows
  • Implement and optimize data pipelines for ingestion, preprocessing, and transformation
  • Integrate AI features into existing applications and ensure smooth end-to-end delivery
  • Continuously evaluate, tune, and improve model accuracy and performance
  • Provide technical leadership, contribute to architectural decisions, and support team standards
  • Mentor less experienced engineers and share ML/AI best practices
  • Work with OCR and image-processing flows to support multimodal search and extraction
  • Contribute to AI agent design and data architecture for automation use cases

Key Skills:

  • 3-6+ years hands-on experience building ML/AI solutions, with at least 2 years using modern LLMs or vector-search ecosystems
  • Strong practical experience with Azure: Azure OpenAI, Cognitive Search or vector indexing, Data Factory, Databricks, AKS/ACA, Key Vault, App Configuration
  • Proven experience creating embeddings, designing semantic indexes, and working with similarity search / ANN libraries
  • Solid programming skills in Python and familiarity with ML frameworks (transformers, sentence-transformers, scikit-learn, PyTorch/TensorFlow)
  • Advanced prompt engineering skills, including templates, safety/guardrails, and production prompt workflows
  • Data engineering experience (ETL/ELT pipelines, batch/stream processing, data quality, metadata)
  • Knowledge of OCR/image processing tools (Tesseract, Azure Form Recognizer, OpenCV or similar)
