[Hiring] Freelance Data Scientist (Python & SQL) - AI Trainer @Mindrift

1mth ago - Mindrift is hiring a remote Freelance Data Scientist (Python & SQL) - AI Trainer. πŸ’Έ Salary: usd 34 per hour πŸ“Location: Poland

Role Description

This role involves collaborating on AI projects as a Data Science AI Trainer, focusing on improving GenAI models to address specialized questions and achieve complex reasoning skills.

  • Design original computational data science problems that simulate real-world analytical workflows across industries (telecom, finance, government, e-commerce, healthcare).
  • Create problems requiring Python programming to solve (using pandas, numpy, scipy, sklearn, statsmodels, matplotlib, seaborn).
  • Ensure problems are computationally intensive and cannot be solved manually within reasonable timeframes (days/weeks).
  • Develop problems requiring non-trivial reasoning chains in data processing, statistical analysis, feature engineering, predictive modeling, and insight extraction.
  • Create deterministic problems with reproducible answers: avoid stochastic elements or require fixed random seeds for exact reproducibility.
  • Base problems on real business challenges: customer analytics, risk assessment, fraud detection, forecasting, optimization, and operational efficiency.
  • Design end-to-end problems spanning the complete data science pipeline (data ingestion β†’ cleaning β†’ EDA β†’ modeling β†’ validation β†’ deployment considerations).
  • Incorporate big data processing scenarios requiring scalable computational approaches.
  • Verify solutions using Python with standard data science libraries and statistical methods.
  • Document problem statements clearly with realistic business contexts and provide verified correct answers.

Qualifications

  • Master’s or PhD Degree in Data Science, Statistics, Mathematics, Computer Science, or related quantitative field.
  • At least 5 years of hands-on data science experience with proven business impact.
  • Portfolio of completed projects and publications showcasing real-world problem-solving.
  • Proficient in Python programming for data science (pandas, numpy, scipy, scikit-learn, statsmodels).
  • Expert in statistical analysis and machine learning with deep understanding of algorithms, methods, and their practical applications.
  • Proficient in SQL and database operations for data manipulation and analysis.
  • Experience with GenAI technologies (LLMs, RAG, prompt engineering, vector databases).
  • Good understanding of MLOps practices and model deployment workflows.
  • Knowledge of modern frameworks (TensorFlow, PyTorch, LangChain).
  • Advanced level of English (C1) or above.
  • Ready to learn new methods, able to switch between tasks and topics quickly and sometimes work with challenging, complex guidelines.

Benefits

  • Get paid for your expertise, with rates that can go up to $34/hour depending on your skills, experience, and project needs.
  • Take part in a part-time, remote, freelance project that fits around your primary professional or academic commitments.
  • Work on advanced AI projects and gain valuable experience that enhances your portfolio.
  • Influence how future AI models understand and communicate in your field of expertise.
