    Our mission is to redefine the online casino experience by offering a uniquely transparent environment where players can relax, unwind, and enjoy themselves safely. We are committed to accessibility, fairness, and inclusivity, fostering a community of like-minded individuals who value ethical gaming practices and prioritize our players' safety and enjoyment above everything else.

    • Bring the Olives – we offer premium customer experience.
    • Think Big – we believe in always striving for more.

    Key Responsibilities
    • Design, build, test, and deploy predictive and prescriptive models (e.g., churn prediction, player lifetime value, segmentation, risk classification, fraud detection).
    • Analyze large-scale player behavioral data to identify key value drivers and recommend optimizations for promotions, engagement, and monetization strategies.
    • Develop models for anomaly detection, fraud prevention, and responsible gaming interventions to maintain a safe and compliant environment.
    • Design and evaluate A/B and multivariate tests for product features and marketing campaigns, ensuring statistically robust insights.
    • Partner with Data Engineers to ensure model pipelines are production-ready, automated, and scalable across cloud environments.
    • Visualize and present analytical findings to both technical and non-technical stakeholders, driving clear, data-informed decisions.
    • Monitor and refine model performance, automate recurring analyses, and ensure data quality and reproducibility.
    Requirements
    • 3+ years of experience in a Data Scientist, Machine Learning Engineer, or advanced analytics role (ideally within iGaming, FinTech, or other consumer-facing digital products).
    • Strong theoretical understanding of machine learning and statistical algorithms (classification, regression, clustering, optimization).
    • Proven experience applying models to solve business problems (e.g., forecasting, segmentation, retention, player value optimization).
    • Skilled in Python (Pandas, NumPy, Scikit-learn, PySpark) and SQL (advanced querying, ETL processes, performance optimization).
    • Experienced in analyzing massive datasets (100M+ rows) across multiple sources.
    • Strong communication skills — able to explain complex technical concepts to non-technical audiences.
    Nice to Have
    • Experience with AWS, Docker, Kubernetes, or other cloud and containerization technologies.
    • Background in NLP, time-series, or causal inference modeling.
    • Proficiency with data visualization tools (Tableau, Looker, or Power BI).
    • Experience integrating data and models into production pipelines and dashboards.
    • Familiarity with iGaming KPIs such as LTV, ARPDAU, Churn, and Player Retention metrics.
    • Understanding of A/B testing frameworks and experimental design.
