The whole process takes from a few weeks to several months.

We’re Seeking Someone With The Following Experience

• Python and data science concepts.
• Experience with at least one cloud platform (AWS preferred).
• Some NLP projects experience,
• Practical knowledge of vector search, graph databases, or full-text search.
• Experience with workflow automation and orchestration tools (Airflow, Temporal, Prefect, or similar).
• Understanding of LLM-based AI pipelines, including Zero-shot/Few-shot learning, Chain-of-Thought (CoT), and function calling.
• English at B2 level at least.
  
  

If you have a strong background in these areas and are available for a long-term project, we’d love to hear from you!

Requirements

• Designing and implementing data pipelines for document processing, storage, and retrieval.
