Overview

Ravenworth Labs has an opening for a Senior Data Scientist. This hire will own our demand forecasting models and the process for keeping them accurate as conditions change. Expect messy, real data and a fair amount of time on feature engineering and validation. We are headquartered in Los Angeles and have been hiring remotely since 2020.

What you need

• Data visualization in matplotlib, seaborn, Plotly or a BI tool.

• Solid grasp of statistical inference, regression and experimental design.
• Familiarity with Git and working in shared codebases.
• Comfort with Jupyter, VS Code or Databricks notebooks.

Preferred
