Job Description

Design Data Science Problems for AI Training

As a Data Science AI Trainer, you will design original computational problems that simulate real-world analytical workflows across various industries. These problems will require Python programming using libraries like pandas, numpy, scipy, sklearn, statsmodels, matplotlib, and seaborn. It is important that the problems created are computationally intensive and cannot be solved manually within reasonable timeframes.

  • Create deterministic problems with reproducible answers.
  • 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.

Your Responsibilities as a Data Science AI Trainer

Your tasks include creating problems that require non-trivial reasoning chains in data processing, statistical analysis, feature engineering, predictive modeling, and insight extraction. The ability to incorporate big data processing scenarios requiring scalable computational approaches is essential for a successful Data Science AI Trainer.

  • 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.
  • Contribute to projects aligned with your skills, on your own schedule.

Requirements for the Data Science AI Trainer Role

To excel as a Data Science AI Trainer, you should hold a Master’s or PhD Degree in Data Science, Statistics, Mathematics, Computer Science, or a related quantitative field. A minimum of 5 years of hands-on data science experience with proven business impact is required. A portfolio of completed projects and publications showcasing real-world problem-solving is highly desirable. Learn more about data science here.

Proficiency in Python programming for data science, SQL, and database operations is crucial. Experience with GenAI technologies (LLMs, RAG, prompt engineering, vector databases), a good understanding of MLOps practices, and knowledge of modern frameworks (TensorFlow, PyTorch, LangChain) are also important.

Benefits of Freelancing as a Data Science AI Trainer at Mindrift

This freelance opportunity offers numerous benefits. You will get paid for your expertise, with rates that can go up to $46/hour depending on your skills, experience, and project needs. It allows you to take part in a part-time, remote project that fits around your primary professional or academic commitments. You will also work on advanced AI projects and gain valuable experience that enhances your portfolio. Furthermore, you'll influence how future AI models understand and communicate in your field of expertise.

This role is fully remote, requiring only a laptop, internet connection, time available, and enthusiasm to take on challenges. See what's trending in AI on ...
