- Experience applying operations research techniques such as optimization, simulation, queuing theory, or decision modeling to improve operational outcomes
- Deep expertise in statistical analysis, experimentation, and inference on real-world data
- Hands-on experience building predictive and prescriptive models (e.g., classification, regression, anomaly detection, routing)
- Expert SQL skills, including complex joins, window functions, and performance optimization
- Excellent Python skills for data analysis, modeling, optimization, and production-ready workflows
- Experience working with large, messy, and incomplete datasets, including both structured and unstructured data
- Excellent communication skills, with experience presenting complex analytical or optimization results to non-technical stakeholders and influencing product strategy, operational decisions or roadmap priorities
- Track record of driving measurable business or client impact through data science and/or operations research work
