Data Scientist

Company overview

We are a small, self-funded team building a booking app for independent salons and tattoo studios. Chalkside Labs is a 14-person software shop in New York City. The founders still answer support tickets. Most engineers work remotely and come into the office one week a quarter for planning.

This role opened up after a team member moved internally. The operations team works directly with product and finance. You'll design experiments, build forecasts and explain the results. Remote, open to candidates across the US. Normal working hours, Monday to Friday. We use Slack, Notion and Google Meet. Cameras on for team calls.

• Validate model performance and document assumptions and limitations
• Segment customers and build churn and lifetime value models

• Pull and shape data with SQL from Snowflake, BigQuery or Databricks
• Develop time series forecasts with Prophet, statsmodels or gradient-boosted approaches
• Translate vague business questions into problems the data can actually answer

Minimum qualifications

• 3-5 years of applied data science experience
• Comfort with Jupyter, VS Code or Databricks notebooks
• Solid grasp of statistical inference, regression and experimental design
