The Opportunity:
We are hiring multiple Data Scientists to embed within our Operations divisions and support leadership in making data-informed decisions. We are interested in Senior and Lead Data Scientists.
We believe Data Science involves four key elements:
- Data Analysis: including data cleansing, complex SQL queries, and delivering actionable insights.
- Dashboard and report creation to make data understandable for all stakeholders.
- Writing Python, following SDLC best practices, using Git, and creating data products in dbt.
- Experiment design, causal inference, hypothesis testing, feature engineering, and ML model development and deployment.
You don’t need to excel in all areas initially; we support your growth in less familiar skills over time.
Data Scientists will primarily focus on Data Analysis & Visualization, while Lead Data Scientists should have strong expertise across all four elements.
