About AI Training & This Role

AI training includes a wide range of human-centered tasks that help models learn from examples — from annotation to building datasets and evaluating model outputs. This role focuses on the data engineering and visualization side: preparing, validating, and presenting data so teams can draw reliable insights.

This is a part-time contractor position (less than 20 hours/week), open worldwide and paid hourly at $25 USD. It is listed at an entry-level experience level and is remote.

What You’ll Do

You will build and maintain data pipelines, clean and transform datasets, and create interactive dashboards that communicate insights clearly. Your work will help turn business questions into validated metrics and visualizations and will be iterated based on stakeholder feedback.

• Develop ETL/data pipelines to extract, transform, and load datasets for analysis.
• Implement visualizations using Plotly and create interactive dashboards with Dash.
• Optimize SQL queries and data models for performance and maintainability.
• Validate data quality and document data validation checks and assumptions.
• Write clear documentation for data workflows, dashboards, and code.
• Collaborate to translate business questions into measurable metrics and visuals.

Requirements

You must have demonstrable, hands-on experience with the technical skills listed below. We do not require a specific degree — practical ability and good documentation habits matter most.

• Strong Python for data analysis, including pandas and numpy.
• Visualization expertise with matplotlib, seaborn, and plotly.
• Hands-on experience building dashboards with Dash (preferred).
• Experience designing and maintaining data pipelines / ETL processes.
• Solid SQL skills for data extraction and transformation.
• Understanding of data modeling, data quality, and validation practices.
• Familiarity with Git/version control and basic testing practices for data code.
• Clear written communication and thorough documentation of pipelines and dashboards.
• Power BI or Tableau experience is a plus but not required.

Who Should Apply

This role is a good fit for early-career data analysts, junior data engineers, or anyone who has practical Python/SQL experience and a strong interest in building clear, production-ready dashboards. If you enjoy turning messy data into reliable metrics and interactive visuals, apply.
