• Professional Experience: real‑world experience in data analysis, predictive modeling, or machine learning engineering.
• Technical Rigor: the ability to solve complex statistical problems and interpret high‑level data visualizations independently.
• Analytical Mindset: strong attention to detail with the ability to identify subtle logical fallacies in statistical reasoning or data interpretations.
• LLM Fluency: significant experience using LLMs to assist with data workflows, with a clear understanding of where these models typically hallucinate or fail.
• Communication: the ability to explain complex mathematical concepts or data insights clearly and concisely.
• PayPal account to receive payment from our clients.

Responsibilities

• Evaluate LLM Responses: review AI‑generated data insights and statistical analysis for accuracy, clarity, and completeness.
• Fact‑Check Technical Claims: use authoritative references to validate mathematical proofs, statistical formulas, and data‑driven conclusions.
• Validate Code & Outputs: execute data‑related scripts (e.g., Python/R) to ensure they produce correct results and handle edge cases properly.
• Annotate Model Performance: identify strengths and weaknesses in how a model reasons through data problems or builds predictive models.
• Ensure Alignment: verify that model responses follow specific system guidelines and maintain a high standard of professional technical behaviour.

Key Technologies

• Programming: proficiency in Python (Pandas, NumPy, Scikit‑learn) or R.
• Data Querying: advanced SQL for complex data extraction and manipulation.
• Visualization: experience with tools like Tableau, PowerBI, or Matplotlib/Seaborn.
• Modeling: deep understanding of Machine Learning frameworks (PyTorch, TensorFlow) and statistical modeling techniques.
