Description

  • Design original computational data science problems that simulate real-world analytical workflows across multiple industries.
  • Create Python-based problems using libraries such as Pandas, NumPy, SciPy, scikit-learn, Statsmodels, Matplotlib, and Seaborn.
  • Develop computationally intensive tasks that cannot be solved manually within reasonable timeframes.
  • Build problems that require multi-step reasoning in data processing, statistical analysis, feature engineering, predictive modeling, and insight extraction.
  • Create deterministic problems with reproducible answers, using fixed random seeds when needed.
  • Base problem scenarios on real business challenges such as customer analytics, risk assessment, fraud detection, forecasting, optimization, and operational efficiency.
  • Design end-to-end data science tasks spanning ingestion, cleaning, EDA, modeling, validation, and deployment considerations.
  • Incorporate big data processing scenarios that require scalable computational approaches.
  • Verify solutions using Python and standard data science libraries and statistical methods.
  • Document problem statements clearly and provide verified correct answers in realistic business contexts.

Requirements

  • 5+ years of hands-on data science experience with demonstrated business impact.
  • A portfolio of completed projects and publications showing real-world problem-solving.
  • Expert Python programming for data science using pandas, numpy, scipy, scikit-learn, and statsmodels.
  • Expert-level statistical analysis and machine learning knowledge, including practical understanding of algorithms and methods.
  • Expert SQL and database operation skills for data manipulation and analysis.
  • Experience with GenAI technologies such as LLMs, RAG, prompt engineering, and vector databases.
  • Understanding of MLOps practices and model deployment workflows.
  • Knowledge of modern frameworks such as TensorFlow, PyTorch, and LangChain.
  • Strong written English proficiency at C1 level or higher.
  • Willingness to work on part-time, non-permanent, project-based assignments.

Benefits

  • Up to $58 per hour equivalent compensation, depending on level and pace of contribution.
  • Project-based work with the ability to participate in active phases estimated at 10–20 hours per week.
  • Opportunity to work with leading tech companies on AI-related projects.
  • Flexible, non-permanent participation model rather than a full-time employment commitment.
  • Pay varies by project scope, complexity, and required expertise.
