Senior Data Scientist (Spark, feature engineering)

Join MGID as a Data Scientist and become part of a team shaping the future of AdTech!
If you thrive on analyzing data, uncovering hidden patterns, and transforming insights into powerful solutions, this is your chance. We develop cutting-edge algorithms that drive the success of CPA (Cost Per Action) campaigns by achieving target metrics, increasing conversion volume, and maximizing budget efficiency. If you're ready to extract the maximum value from data and make a real impact on product development — we’re waiting for you!

What You Will Do:

• Data Analysis: Explore data to identify trends, evaluate campaign performance, and support decision-making.

• Algorithm Development: Design, implement, and optimize algorithms for CPA optimization.

• Modeling and Optimization: Build and refine predictive models to improve decisions for CPA campaigns, ensuring alignment with business objectives.

• Stakeholder Collaboration: Work closely with product/business teams to translate technical solutions into measurable business impact.

• Experimentation and Validation: Conduct and evaluate A/B tests to assess the impact of algorithm changes.

• Visualization and Reporting: Create dashboards and visualizations to track key performance indicators (KPIs) and communicate findings to stakeholders.

Requirements

Who You Are:

• Proactive problem-solving attitude: ability to independently analyze data, identify hidden issues, formulate hypotheses, suggest effective solutions, develop and test them.

• Ability to analyze and deeply explore data to extract valuable insights; ability to visualize and communicate those insights.

• Proven experience in data science, with a strong understanding of optimization problems.

• Proficiency in Python and SQL, including data manipulation and feature engineering.

• Expertise in machine learning techniques and tools (e.g., CatBoost, XGBoost, TensorFlow, PyTorch, scikit-learn).

• English - Upper-Intermediate.

Will be a plus:

• The ideal candidate holds a MSc or PhD in Engineering, Statistics, Mathematics or related fields

• Familiarity with the AdTech domain.

• Experience with big data technologies (Spark, Hadoop) and processing large datasets.

• Hands-on experience with A/B testing and business metric optimization.

• Background in working with high-frequency or large-scale event data (e.g., 15B+ events daily).
