Jobbeschreibung

#### (Senior) DevOps Engineer (f/m/d)* Hamburg* adjoe* Cloud Engineering* Full timeApply for this jobadjoe 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.**Building Infrastructure behind 5.5 Billion Daily Ad Requests**The Cloud Engineering team is the core of our tech unit, the underlying infrastructure that every other team depends on to ship software and grow the business. Behind rewarded ad experience, the partner-facing dashboards, the ML pipelines, and the ad delivery systems serving millions of users daily, there is one team making sure it all stays online, performant, and cost-efficient.**400 million user events daily**, traffic spikes of **150,000+ requests per second**, and a data lake that feeds data scientists, BIs, and real-time ML inference across the entire ad stack. To handle this reliably and cost-efficiently, the team runs **Kubernetes** with event-driven autoscaling and **Karpenter**, manages **Kafka** clusters for real-time streaming, and provisions everything through Terraform. Rather than defaulting to managed AWS services, the team actively replaces them with open-source alternatives like **Druid, Airflow, Grafana, Prometheus, Spark, Trino, MLFlow, Jupiter Hub, Elasticsearch, and Fluentbit** as part of a deliberate move toward cloud-agnostic architecture. Cost efficiency is treated as an engineering constraint, not an afterthought, including AI-based anomaly detection on infrastructure costs.**Your Mission & Who We Are Looking For:*** **3+ years in DevOps, SRE, or Platform Engineering.** You’ve designed and operated cloud infrastructure at scale, with hands-on experience deploying and managing containerized applications in **Kubernetes**. At adjoe, you’ll be working across a stack that includes **Kafka, Druid, Airflow, Spark, Terraform, and Gitlab** running on Kubernetes clusters across data centers.* **Deep in the AWS ecosystem.** You have a strong understanding of AWS services (**EKS, DynamoDB, SNS, SQS, IAM, Lambda**) and manage infrastructure as code through **Terraform**. You know the tradeoffs between managed AWS services and open-source alternatives, and have opinions about when each makes sense.* **Microservice event-driven architecture is your daily context.** You understand how microservices communicate: topics, queues, object storage, and can support backend teams building high-performance **Go** services across distributed environments.* **Reliable CI/CD is a product requirement.** You build pipelines that are fast, predictable, and low-maintenance, ensuring smooth delivery without becoming a bottleneck.* **Hands-on with emerging infrastructure.** You’re comfortable migrating existing workloads to self-hosted solutions as well as introducing new tools boost business results.**We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.****What’s in It for You?**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 Fast.** Ship solutions multiple times a day, learn from results, and keep momentum.* **Be Direct.** Solve problems openly and collaborate across teams.* **Thrive Together.** Grow with a diverse, global team of people from over 40 different countries that learn from each other.* **Have Fun.** Celebrate wins, enjoy daily victories, and bring your energy.We welcome applications from people who will contribute to the diversity of our company.Apply for this job
