  • 5+ years of professional experience as a Data Scientist or in a closely related analytical role, working on end-to-end machine learning projects.
  • Strong proficiency in Python for data analysis and machine learning, including libraries such as pandas, NumPy, scikit-learn, and related tooling.
  • Solid background in statistics, experimental design, and applied probability, with experience designing and analyzing controlled experiments.
  • Hands-on experience building, evaluating, and deploying machine learning models in real-world business or product environments.
  • Advanced SQL skills and comfort working with large, complex datasets from data warehouses or data lakes.
  • Minimum C1 English proficiency (written and spoken), with the ability to write clear quantitative explanations and follow detailed English-language guidelines.
  • Experience with data visualization tools or dashboards and the ability to present analytical findings to stakeholders.
  • Previous experience with AI data training, annotation, or reviewing AI-generated analytical content is a strong plus.
  • Highly detail-oriented and systematic, with a strong focus on quality, reproducibility, and careful evaluation of reasoning steps.
