Description

  • Design original computational data science problems that reflect real-world analytical workflows across industries such as telecom, finance, government, e-commerce, and healthcare.
  • Create Python-based problems that require libraries such as Pandas, NumPy, SciPy, scikit-learn, Statsmodels, Matplotlib, and Seaborn to solve.
  • Develop computationally intensive tasks that cannot be solved manually within reasonable timeframes.
  • Build problems that require non-trivial reasoning across data processing, statistical analysis, feature engineering, predictive modeling, and insight extraction.
  • Create deterministic, reproducible problems by avoiding stochastic elements or using fixed random seeds.
  • Base problems on realistic business challenges such as customer analytics, risk assessment, fraud detection, forecasting, optimization, and operational efficiency.
  • Design end-to-end data science tasks spanning data ingestion, cleaning, EDA, modeling, validation, and deployment considerations.
  • Incorporate big data processing scenarios that require scalable computational approaches.
  • Verify solutions using Python, standard data science libraries, and statistical methods.
  • Write clear problem statements 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 Python programming for data science, including pandas, numpy, scipy, scikit-learn, and statsmodels.
  • Expert-level statistical analysis and machine learning knowledge, including algorithms, methods, and practical applications.
  • Expert SQL and database operations 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.
  • Willingness to work on part-time, non-permanent, project-based assignments.

Benefits

  • Project-based AI opportunities with leading tech companies.
  • Flexible part-time workload of approximately 10–20 hours per week during active project phases.
  • Compensation of up to $34 per hour equivalent, depending on contribution level and pace.
  • Opportunity to work on varied projects across different industries and problem types.
  • Payment for completed tasks through the platform.
