- Full time
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:
Did you know that in-app ads are sold in a real-time auction before they get rendered by adjoe’s Android and iOS SDK in thousands of mobile apps?
It’s exactly for this that adjoe has built its own platform. Our backend system can simultaneously handle a few billion auctions in real time every day. It receives price bids for every ad impression via API from more than 20 different companies buying potential ad inventory. To handle this many requests, the Programmatic team constantly optimizes its Golang code – to improve memory efficiency and execution time.
Handling this much traffic on scale can also be pretty expensive, so the team introduced Protobuf and different compression options to decrease bandwidth use. The common CRUD DB Repository pattern can limit performance and scalability – so, our software design is based on event sourcing approaches leveraged by Apache Kafka and other streaming technologies.
Join our discussions, explore implementation, and put your problem-solving skills to the test in our cross-functional Programmatic team.
