Working Student - Data Analyst (f/m/d)

adjoe builds the technologies behind mobile apps growth and monetization. With our core product Playtime Arcade, we've become the global leader in rewarded advertising, an ad unit built on a simple premise: users earn real in-app rewards for engaging with new apps. The result is one of the most effective value exchanges in adtech, connecting advertisers and publishers with over 770 million users annually.

Investigating Ad Delivery Algorithms Across 400 Million Daily Events

More than 440 million ad events flow through our systems daily, and the Advertising Analytics team is responsible for understanding, improving, and safeguarding that ad delivery system.

With over 2,000 games from top studios around the world, Data Analysts dig into the algorithms behind ad delivery. They redesign, experiment, and investigate everything across complex, asynchronous ad delivery systems, using Python and Airflow to build the analytical infrastructure that makes that possible. The team owns the business layer: alarms, performance tracking, and Tableau dashboards, which translate analytical findings into clear data-driven decisions for business and product teams, and unlock rapid business scale-up.

Your Mission & Who We Are Looking For:

• SQL-first analytical mindset. You're currently studying Computer Science, Business Informatics, or a related field with hands-on SQL experience. At adjoe, you'll be diagnosing technical and data issues across global operations and analyzing user behavior changes from product experiments and feature rollouts.

• You build, not just report. Beyond one-off investigations, you'll contribute to reporting, monitoring, and alerting systems that improve data visibility for product and business teams. Python experience is a plus.

• Curious about how systems behave in production. You don't just accept the numbers at face value — you dig into why they look the way they do and communicate findings clearly in English to both technical and non-technical stakeholders.

What’s in It for You?

At adjoe, you’re not here to just close JIRA tickets, you’re helping build the infrastructure behind one of the most impactful platforms in adtech. The systems you work on will reach hundreds of millions of users and power billions of decisions every day.

• Go Big. Own projects with impact on 770M users and push adtech boundaries.

• Move Fast. Ship solutions multiple times a day, learn from results, and keep momentum.

• Be Direct. Solve problems openly and collaborate across teams.

• Thrive Together. Grow with a diverse, global team of people from over 40 different countries that learn from each other.

• Have Fun. Celebrate wins, enjoy daily victories, and bring your energy.

We welcome applications from people who will contribute to the diversity of our company.
