AI QA Analyst
Review and annotate complex conversation traces to rate response quality based on metrics such as helpfulness, honesty, and harmlessness (HHH). Build and maintain high-quality "Golden Datasets" and benchmarks to stress-test the model across various domains and edge cases. Conduct pre-deployment testing and A/B model comparisons to identify performance regressions or improvements. Categorize model failures (hallucinations, logic errors, tone drift) to provide actionable feedback to the Engineering and Research teams. Help define and refine the rubric for "what a good response looks like" as the product evolves.
Data Scientist (Python & SQL) - Freelance AI Trainer
As a Data Science AI Trainer, you will design original computational data science problems that simulate real-world analytical workflows across various industries such as telecom, finance, government, e-commerce, and healthcare. You will create problems that require Python programming to solve using libraries like pandas, numpy, scipy, sklearn, statsmodels, matplotlib, and seaborn, ensuring these problems are computationally intensive and cannot be solved manually within reasonable timeframes. Your tasks include developing problems requiring non-trivial reasoning chains in data processing, statistical analysis, feature engineering, predictive modeling, and insight extraction. You will create deterministic problems with reproducible answers by avoiding stochastic elements or using fixed random seeds, base these problems on real business challenges such as customer analytics, risk assessment, fraud detection, forecasting, optimization, and operational efficiency, and design end-to-end problems spanning the complete data science pipeline from data ingestion to deployment considerations. Additionally, you will incorporate big data processing scenarios that require scalable computational approaches, verify solutions using Python with standard data science libraries and statistical methods, and document problem statements clearly with realistic business contexts and provide verified correct answers.
