Descripción de la vacante

Prime Insights, a Sweden-based tech company, is seeking a Data Scientist to build predictive models, recommendation systems, and experimentation frameworks to improve user engagement, LTV, and fraud detection across a high-scale product. You will work in the Central Data Team, applying Python, SQL, and cutting-edge ML tools to optimize targeting, retention, and monetization for our international user base.

Experience in AdTech or Gaming is a strong plus.

Formación

• 3+ years of experience in Data Science, ideally within AdTech, Gaming, or FinTech.
• Core Tech Stack: Expert proficiency in Python (Scikit-learn, XGBoost/LightGBM/CatBoost, PyTorch) and Advanced SQL.
• AdTech Knowledge: Familiarity with CPM, ROAS, Attribution, and Post-back loops.
• Strong communication skills: Able to clearly explain findings, assumptions, and tradeoffs to both technical and non-technical audiences.
• Experimental Design: Deep understanding of A/B testing in high-traffic environments where "noise" is high.
• Product Curiosity: You don’t just build models; you want to understand the psychology of why a user clicks one game over another.

Responsabilidades

• Predictive Targeting & Personalization: Build recommendation engines that match the right offer (game/survey) to the right user at the right time to maximise user engagement.
• User Lifetime Value (LTV) Modeling: Develop models to predict long-term user value and churn, allowing us to optimize user acquisition spend.
• Fraud & Anomaly Detection: Guard the ecosystem by building real-time systems to detect "farming," bot behavior, and VPN spoofing.
• Statistical Rigor: Serve as the internal consultant for experimentation (A/B testing) design, ensuring results are statistically significant and unbiased.
• Advanced Analytics: Move beyond descriptive reporting into diagnostic and predictive analytics.
