Description

  • Design original data science problems that simulate real-world analytical workflows across industries such as telecom, finance, government, e-commerce, and healthcare.
  • Create computational problems that require Python-based solutions using libraries such as Pandas, NumPy, SciPy, scikit-learn, Statsmodels, Matplotlib, and Seaborn.
  • Develop problems that are computationally intensive and cannot be solved manually within a reasonable timeframe.
  • Build tasks that require multi-step reasoning in data processing, statistical analysis, feature engineering, predictive modeling, and insight extraction.
  • Create deterministic problems with reproducible answers by avoiding stochastic elements or using fixed random seeds.
  • Base problem statements on real business challenges such as customer analytics, risk assessment, fraud detection, forecasting, optimization, and operational efficiency.
  • Design end-to-end problems spanning the full data science pipeline from data ingestion and cleaning through 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 with realistic business context and provide verified correct answers.

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-level Python programming for data science, including pandas, NumPy, SciPy, scikit-learn, and statsmodels.
  • Expert 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, including 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 at C1 level or above.
  • Availability for part-time, non-permanent project work.

Benefits

  • Project-based paid work with leading tech companies.
  • Compensation of up to $55 per hour equivalent, depending on level and pace of contribution.
  • Estimated workload of around 10–20 hours per week during active project phases.
  • Flexible participation based on project availability rather than permanent employment.
