Job Description: Fozzy Group is building a next-generation Customer Value Management (CVM) Decision Support System that lives inside our app’s gamified experience layer. Instead of traditional CRM triggers alone, engagement and retention are driven through game mechanics — achievement chains, progress bars, and personalized quests — and we need someone who can turn those mechanics into measurable, data-driven strategy. The project focuses on two major streams: • Engagement Growth: Driving gamification adoption, modeling guest lifecycle, and applying proactive strategies to increase purchase frequency and deepen engagement. • Retention & Loyalty Management: Early churn detection, loyalty preservation, and predictive modeling of customer attrition to implement timely and personalized interventions that reduce churn risk. You’ll work closely with product, game-mechanic designers, CVM, and the wider Data Science team, and your models will directly shape decisions about quest design, reward economics, and lifecycle communication.
Job Responsibilities • Model customer lifecycle stages inside the gamified platform — from first touch through onboarding to habitual engagement — and identifying where drop-off happens • Design and A/B test game mechanics meant to convert guests into active app users (first-order quests, achievement chains, milestone rewards) • Automate customer targeting and personalized offer selection across CVM campaigns • Build next-best-quest / next-best-action logic to personalize each customer’s path through the game • Design predictive triggers for retention interventions and measure whether they’re actually incremental or just rewarding people who’d have stayed anyway • Build and maintain SQL pipelines to aggregate, clean, and transform customer and transactional data from multiple sources • Extensively utilize SQL and dbt to design, develop, and optimize data models within our high-volume data platform, effectively managing and processing multi-billion-row datasets • Develop data preparation pipelines and contribute to deploying ML models for churn prediction, segmentation, and uplift modeling.
Requirements • Bachelor’s Degree in Mathematics / Quantitative Economics / Econometrics / Statistics / Computer Sciences / Finance • At least 2 years of working experience on Data Analytics • Strong mathematical background in Linear algebra, Probability, Statistics & Optimization Techniques • Solid SQL and Python • Experience with BI tools (Power BI, Tableau, Looker) • Knowledge of statistical methods (Hypothesis testing, A/B tests, PCA) • Ability to work independently and structure complex problems into clear solutions.
Preferred • Experience with Airflow, Docker, or Kubernetes for Data Orchestration • Spark/Trino and Lakehouse experience is a plus • Applied knowledge of Machine Learning (e.g., Decision Trees, Random Forest, and Boosting).
What We Offer • Competitive salary; • Professional & personal development opportunities; • Being part of dynamic team of young & ambitious professionals; • Corporate discounts for sport clubs and language courses; • Medical insurance package.
