● Cross Functional Integration: Work closely with Engineering and Product teams to ensure seamless delivery of these complex feeds into client workflows, while maintaining the integrity of our internal IP.

Requirements:

Domain Knowledge: A strong understanding of cricket and the factors influencing match state outcomes (win probability, expected metrics like xR/xW)
Technical Grounding: Degree in Mathematics, Data Science, Computer Science, or a related quantitative field with a strong grounding in machine learning and statistics.
Practical Experience: Proven track record (2+ years) of applying data science methods as part of end-to-end pipelines (feature engineering, model training, deployment, validation) to solve complex real-world problems in a professional environment.
Programming Fluency: Strong programming skills in Python and SQL plus specific proficiency with the PyData stack (pandas, numpy, scikit-learn, XGBoost, LightGBM)

Desirable
● Tracking Data Experience: Prior experience working with high-frequency tracking or GPS data to create aggregated, value-add insights.
● Strategic Communication: Ability to translate highly technical modeling concepts into clear commercial value propositions for sophisticated stakeholders.
● Discretion & IP Management: Experience working in sensitive commercial environments where protecting proprietary modeling work is paramount
