  • Strong portfolio of completed projects or publications.
  • Excellent written English (C1+).

Required skills

  • Python programming (Pandas, NumPy, SciPy, scikit‑learn, StatsModels, Matplotlib, Seaborn).
  • SQL for data manipulation and analysis.
  • Advanced statistical analysis and machine‑learning techniques.
  • Experience with GenAI technologies (LLMs, RAG, prompt engineering, vector databases).
  • Understanding of MLOps practices and model deployment workflows.
  • Familiarity with TensorFlow, PyTorch and LangChain.

What we offer
