Staff Go Backend Developer

The Demand Core team and backend platform squads build the foundational infrastructure that determines which of thousands of active advertising campaigns are relevant to a user the moment they open Playtime. At adjoe's scale, system latency is a business failure: downtime means advertisers stop spending, users stop earning rewards, and publisher revenue stalls. As a Staff Backend Developer, you will own the architectural integrity, reliability, and long-term evolution of the distributed systems that power these decisions 200 million times every day, across multiple teams.

Go microservices load the active ad campaign catalog into memory, evaluating 40+ targeting constraints and 30+ real-time signals (such as geo, fraud status, and budget caps) to rank potential user performance in milliseconds.

Beyond individual services, you will define architectural patterns across the entire ad interaction chain:

* High-throughput processing of clicks, views, MMP postbacks from Adjust and AppsFlyer, and reward-triggering in-app events * Governing our hybrid messaging architecture using SNS/SQS and Kafka * Standardizing backend data patterns across DynamoDB, relational, and analytical data stores * Ensuring our core ad scoring pipelines remain resilient under massive load

You're not here to just close JIRA tickets; you're shaping the architectural foundation behind one of the most impactful platforms in adtech. The systems and patterns you design will reach hundreds of millions of users and power billions of decisions every day.

* Go Big. Own the technical direction and platform architecture with impact on 770M users and push adtech boundaries. * Move Fast. Ship solutions multiple times a day, establish golden paths that unlock engineering speed, and keep momentum. * Be Direct. Solve complex architectural bottlenecks openly and drive alignment across cross-functional teams. * Thrive Together. Grow with and elevate a diverse, global team of engineers from over 40 different countries that learn from each other. * Have Fun. Celebrate wins, solve hard computer science challenges, and bring your energy.
