# Senior Go Backend Developer (Supply Integrations Team) (f/m/d)adjoeVia arbeitnowHamburg, DEPubliée il y a 5h## Description du posteadjoe 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.**Processing 2+ million daily interactions between adjoe's reward engine and its global publisher network** The Supply Integrations team builds and operates the services that ensure every user reward is calculated, verified, and delivered, whether that means firing a cryptographically signed **HTTP callback** in milliseconds or transferring loyalty points through a partner's **OAuth-secured payment API**. Every callback that lands on time is a reward delivered, a publisher retained, and revenue protected. The team's production surface spans a set of services connecting adjoe to a global publisher network. **S2S Payout Callbacks** deliver real-time reward notifications with **40+ configurable parameters,** secured by per-publisher cryptographic signatures. The **Payout Adapter** integrates directly with enterprise partner payment systems, handling **OAuth2** flows, **mTLS**, **HMAC signatures**, and retry logic to guarantee delivery. Our External Statistics API aggregates data from Druid, Athena, and DynamoDB into self-serve publisher dashboards and daily reports. All of this is backed by Go microservices communicating over Kafka and SQS, with state managed in **DynamoDB** and **MySQL**, processing over **2 million interactions every day** without missing a beat.## Your Mission & Who We Are Looking For* **Production Golang Systems Expertise:** You bring 5+ years of backend development experience, including at least 3 years writing Go in production distributed environments. You will build and maintain our +99% Go microservice architecture—interfacing with our TypeScript/React frontend—to reliably handle 2+ million daily publisher interactions and scale beyond hundreds of millions of monthly active users.* **High-Throughput Event Streaming:** You have hands-on experience designing asynchronous microservice communication using event buses like Kafka, SQS/SNS, and Kinesis. You will build pipelines to collect billions of daily API events and aggregate them into our data lake for sub-second querying.* **High-Scale Data & API Optimization:** You understand database internals and low-level web standards (HTTP protocol, Encoding, Regular Expressions). You will optimize queries across hundreds of terabytes of data across DynamoDB, MySQL, Druid, and Athena to reduce API response times and expose transparent, well-documented open APIs to enterprise partners.* **Data Science & Algorithmic Integration:** You quickly grasp complex technical topics and applied mathematics. You will partner directly with our Data Science team to translate and integrate machine learning algorithms into adjoe’s core application, optimizing real-time ad targeting.* **Collaborative Technical Communication:** You communicate fluently and precisely in spoken and written English. You will actively participate in peer code reviews and technical knowledge sharing across an international backend engineering team.* **Plus: Infrastructure & Cloud Tooling:** Hands-on experience with Terraform (Infrastructure as Code), Docker containerization, or serverless infrastructure.** We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.**At adjoe, you’re not here to just close JIRA tickets, you’re helping build the infrastructure behind one of the most impactful platforms in adtech. The systems you work on will reach hundreds of millions of users and power billions of decisions every day.* **Go Big.** Own projects with impact on 770M users and push adtech boundaries.* **Move Fa...**
