Product Owner (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.

Transforming 50M+ daily events into real-time actionable dashboard insights

The Dashboards team is responsible for the systems and interfaces that define our partners' daily operations. We build the campaign management APIs, analytics engines, and high-throughput tools that allow advertisers and publishers to configure, monitor, and optimize their activity on our platform.

This is not about simple CRUD interfaces, it is about building high-performance data surfaces that drive massive business decisions. Using Go, Kafka, and Druid, we process and render real-time analytics across 50+ million daily events, ensuring accuracy and complex campaign performance reporting at scale. On the frontend, we tackle genuine engineering constraints: utilizing TypeScript and React, we have moved beyond standard library limitations to build highly optimized graph-rendering with Recharts capable of visualizing datasets that would overload conventional solutions.

Your Mission & Who We Are Looking For:

• 3+ years as a Product Owner in a fast-paced environment. You have hands-on experience with agile development and a track record of taking features from concept to launch. At adjoe, you'll own the Advertiser Tools product end-to-end, managing a dedicated development team, driving the roadmap, and making strategic decisions that directly impact advertiser performance.
• High ownership, low ambiguity tolerance. You prioritize ruthlessly based on user and business needs, work independently, and make objective calls when requirements are still evolving. You've delivered at least one significant 0-to-1 product iteration and know what it takes to ship at pace without sacrificing quality.
• Bridges business and engineering naturally. You're as comfortable presenting a product roadmap to management and external partners as you are discussing technical tradeoffs with engineers. You close the gap between what the business wants and what the system can realistically deliver.
• KPI-driven team lead. You manage team progress with a strong focus on delivering measurable impact for our advertisers and create solutions that meet their goals.
• Develops the people, not just the product. You guide and grow the individuals on your team, helping them operate at their best even as requirements and priorities shift.
• Plus: AdTech background. Experience in an adtech company is a plus, not a requirement.

🌎 We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.
