We are looking for a Senior Data Scientist to help build data-driven products that significantly improve customer experience on a large-scale betting platform. You will work on high-impact machine learning models, take full ownership from research to production, and directly influence product and business decisions.
This role goes beyond modeling — you will deploy models into production, run experiments, monitor results, and partner closely with product and business teams.
You will work on models and systems such as: * Churn, retention and LTV prediction; * Risk scoring, fraud and responsible gambling models; * Personalization and recommendation systems; * Uplift and causal models to drive product decision; * Real-time ML systems powering user experience; * Experimentation frameworks and A/B testing.
What you’ll be doing: * Design, train and productionize machine learning models for product, risk and personalization use cases; * Own models end-to-end: data exploration, feature engineering, modeling, deployment and monitoring; * Design and analyze A/B tests to measure the real business impact of models and product changes; * Collaborate closely with product managers, engineers and analysts to translate business problems into ML solutions; * Monitor model performance, data quality, drift and key business metrics after deployment; * Communicate insights and recommendations to business and product stakeholders.
What we’re looking for: * 4+ years of experience as a Data Scientist or in a similar applied ML role; * Strong hands-on experience with Python and SQL; * Proven experience building and deploying ML models in production; * Experience with churn, LTV, behavioral or risk-related models; * Solid understanding of statistics, experimentation and A/B testing; * Ability to clearly explain technical results to non-technical stakeholders.
Nice to have: * Experience in gaming, fintech or other high-scale consumer products; * Experience with recommendation systems or risk/fraud models; * Familiarity with cloud environments and basic MLOps practices; * Experience working with real-time or near real-time ML systems.
