The role:

Tillerhall is looking for a Senior Data Scientist to join a small, steady team. Applied data science role. We care more about whether your model gets used than about its AUC on a holdout set.

• Present findings to product, marketing and finance leaders with clear recommendations
• Review peers' analyses for statistical correctness
• Develop time series forecasts with Prophet, statsmodels or gradient-boosted approaches
• Pull and shape data with SQL from Snowflake, BigQuery or Databricks

What you need:

• 5+ years of applied data science experience
• Ability to communicate uncertainty and tradeoffs to non-technical audiences
• Data visualization in matplotlib, seaborn, Plotly or a BI tool
• MS or PhD in statistics, economics, computer science, physics or another quantitative field, or a BS plus equivalent experience

Nice to have:
