- Anti-Fraud Solutions
- Full time
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.
Ensuring Authenticity for Billions of Daily Rewards
Industry reports suggest 25 percent of global mobile ad spend is lost to fraudulent activities like click farms, fake installs, SDK spoofing, and emulator farms. At adjoe, we define our platform through trust and proactive engineering. We build high-performance defenses that guarantee accurate reward attribution, ensuring every interaction is authentic. This creates a sustainable value exchange that empowers our partners to grow with confidence.
The Anti-Fraud team develops systems that detect and prevent malicious activity at scale. Our custom Android and iOS SDKs analyze device integrity for modifications like Xposed frameworks, Magisk modules, and jailbroken devices. Supporting these, Go microservices and DynamoDB deliver millisecond-level responses, while Kafka and SQS process billions of daily events in real time. This infrastructure protects publisher margins and ensures a trustworthy platform for all users.
Your Mission & Who We Are Looking For:
Architecting High-Scale Go Microservices: You have several years of experience as a software architect or senior software developer with outstanding Go expertise in professional backend environments. You will maintain our microservices architecture and scale the platform beyond hundreds of millions of monthly active users using cloud infrastructures like AWS, Azure, or Google Cloud.
Event-Driven Pipeline Engineering: You have experience building event-driven systems using Kafka and SQS/SNS. Your mission is to establish reliable asynchronous microservice communication, collect billions of daily API events, and aggregate them in Kafka streams so they can be queried from our data lake in a matter of seconds.
Low-Latency NoSQL Database Design: You bring extensive experience with large-scale key-value databases such as DynamoDB, Cassandra, or ScyllaDB. You will deploy this knowledge to optimize our database layer, ensuring we consistently deliver few-millisecond response times to block fraudulent transactions in real time.
Technical and People Leadership: You have a proven track record of managing people, mentoring developers, and setting technical direction in fast-changing environments. You will lead our backend engineers, establish high engineering standards, and run peer code reviews to foster alignment across our international team.
Adversarial Fraud Investigation: You think like a hacker and naturally find ways around systems that block your progress. You will investigate novel fraud complaints, collaborate with mobile developers to reproduce exploits or cheats, and continuously improve our systems to counter evolving Android and iOS threats.
Plus: Mobile Development Fundamentals: Basic knowledge of Android or iOS development is a plus. This understanding will help you collaborate with mobile engineers to analyze device integrity modifications like Xposed frameworks, Magisk modules, and jailbroken devices.

Additionally, you get three whole weeks per year to work fully remotely if you want.

Well next to the fact that you are able to see and collaborate with your colleagues face-to-face, we have a super modern office that leave no wishes open: from Drinks & Snack, areas to work away from your desk to a fully equiped gym.
