About AI training work

AI training (also called data labeling or human feedback work) is the human side of building intelligent systems. Modern models learn from examples prepared and reviewed by people — and data analysis is a critical part of ensuring those examples are high quality and useful.

Contributors do everything from preparing datasets and rating outputs to analyzing trends that guide model improvements. This role supports those efforts by turning raw text data into reliable, actionable insights.

What you'll do

• Analyze large datasets to uncover trends, patterns, and actionable insights that support AI learning objectives.
• Develop, optimize, and maintain advanced PL/SQL queries for efficient data extraction, transformation, and manipulation.
• Write Python scripts for automation, data cleaning, and statistical analysis.
• Create comprehensive reports and visualizations to communicate findings to technical and non-technical stakeholders.
• Collaborate remotely with cross-functional teams to define data requirements and deliver data-driven solutions.
• Document processes and methodologies with meticulous attention to detail to ensure reproducibility.
