What We're Looking For

We're looking for a Senior Marketing Data Analyst to join the Marketing Analytics team (part of the Data Department) and contribute to one of our flagship products.

Challenges you'll meet:

  • Provide analytical support to user acquisition (UA) stakeholders on your dedicated app across multiple levels. Core stakeholders are UA Leads and Head of Growth;

  • Carry out complex analysis of datasets and conduct appropriate data validation for web UA across multiple paid channels (Paid Social, Search, Display, Affiliates/Partnerships, etc.);

  • Translate business questions and hypotheses into structured analytical research, automations or data pipeline improvements;

  • Partner with dedicated Data Engineering, BI and Data Science teams to improve data quality and measurement, and turn insights into measurable business impact;

  • Review marketing performance and explain key trends (in revenue, ROI/PAM, audience shifts) to inform decision making.

Your professional qualities:

  • 5+ years of analytics experience, including 3+ years as Marketing Data Analyst (performance/UA);

  • Advanced SQL (window functions, CTEs, performance-aware querying, data quality checks) and experience working with large data warehouses;

  • Proven experience partnering with performance marketing / UA stakeholders and communicating insights to non-technical audiences;

  • Experience with visualization tools (Tableau, Looker, or similar). Tableau is our primary BI tool;

  • Solid understanding of marketing metrics, cohort analysis, segmentation, and deep-dive research;

  • Experience analyzing major network data (Meta / Google / TikTok / AppLovin, etc.) Meta is a strong plus;

  • Understanding of UA web funnel and conversion drivers;

  • Hands-on LTV calculations (ideally subscription monetization);

  • Structured thinking: clearly articulates approach, assumptions, tradeoffs, and conclusions;

  • Ability to work on several projects at a time, plan, prioritize and meet deadlines;

  • Ability to communicate effectively in English (written + spoken).

Nice to have:

  • A/B test planning, preparations, and analysis. A/B testing experience in user acquisition and/or creative testing is a huge plus.

  • Familiarity with web/app attribution and their tools such as Appsflyer, Adjust, GA4, Firebase, SKAdNetwork

  • Knowledge of Python (numpy, pandas, scikit-learn, etc.)
