The role designs statistical and machine learning solutions that translate messy, high-dimensional data into clear business insight.
The work spans the full spectrum: you will write production SQL one day and design a causal inference study the next. Scientific rigor and business impact matter in equal measure.
Key Responsibilities
- Develop, validate, and deploy predictive models (regression, classification, clustering, time-series) for real business decisions across client verticals
- Design and analyze A/B tests and quasi-experimental studies with appropriate statistical rigor; communicate results to business and executive stakeholders
- Write efficient, well-documented SQL and Python analytical code; maintain model pipelines with appropriate quality monitoring
- Collaborate with data engineers on feature engineering, data quality, and pipeline reliability for training and serving
- Conduct exploratory data analysis to surface non-obvious patterns and generate hypotheses that drive product roadmap decisions
- Present findings clearly in written reports, dashboards, and executive presentations - translating statistical nuance into confident recommendations
- Contribute to team knowledge-sharing; stay current on methodological advances relevant to our problem spaces
- 2–5 years of data science experience with demonstrable production impact (not just analyses - decisions that changed what someone did)
- Strong Python: pandas, scikit-learn, statsmodels; SQL at the level of writing and optimizing complex analytical queries without help
- Deep statistical foundations: hypothesis testing, regression modeling, experimental design, probability distributions
- Experience with at least one cloud data warehouse: Snowflake, BigQuery, or Redshift
- Clear, structured written and verbal communication - you can make a p-value meaningful to a CFO
- MS or BS in Statistics, Computer Science, Mathematics, Economics, or a closely related quantitative field
- Bonus: causal inference methods (DiD, synthetic control, IV), ML model deployment experience, Spark, or NLP
