Senior Go Backend Developer (Playtime Supply) (f/m/d)

adjoe is a leading mobile ad platform developing cutting-edge advertising and monetization solutions that take its app partners’ business to the next level. Part of the applike group ecosystem, adjoe is home to an advanced tech stack, powerful financial backing from Bertelsmann, and a highly motivated workforce to be reckoned with.

Meet Your Team: Playtime Supply

Playtime Supply is building a unique software solution for app and game developers that puts users’ needs first. Instead of traditional monetization mechanisms, Playtime builds an engaging ad experience in which users can play and earn rewards for various new mobile games in Playtime. To predict which mobile game will best suit a user, the team has introduced ML algorithms.

To build this rewarded experience, adjoe’s backend reliably handles more than 200 million users – remaining stable despite impressive growth in the user base. And imagine this: adjoe’s Golang event consumer applications assign rewards equivalent to 700 months of time spent in Playtime every day to its users.

The software depends on two main components.
1) adjoe’s Android mobile SDK – written in a combination of Java and Kotlin – which can be bundled by developers in their apps.
2) The team’s highly scalable Golang backend, which is hosted on AWS and is otherwise responsible for developing a modern React (TypeScript) dashboard that provides adjoe’s clients and Business team colleagues with fast-loading insights.
