Cloud Engineer

About the Role

Join adjoe's Cloud Engineering team to build and operate scalable, cost-efficient infrastructure behind Playtime Arcade, supporting hundreds of millions of users and billions of events each day. You will help keep the adtech platform online, performant, and cost-aware as we migrate toward cloud-agnostic, self-hosted tooling.

What You'll Do

• Design, deploy and operate cloud infrastructure at scale across data centers using Kubernetes, Terraform, and an open stack including Kafka, Druid, Airflow, Spark, and more.

• Run Kubernetes clusters with event-driven autoscaling (Karpenter), manage Kafka for real-time streaming, and provision infrastructure as code.

• Build and maintain data pipelines, a data lake, and inference-ready ML workflows that feed data scientists and BI.

• Drive cost efficiency with AI-based anomaly detection on infrastructure costs and evaluate managed AWS vs open-source alternatives.

• Migrate workloads to self-hosted solutions and introduce new tools that boost business results.

• Deliver reliable CI/CD pipelines that are fast, predictable, and low-maintenance using GitLab across distributed environments.

• Collaborate with backend teams building high-performance Go services and support across distributed systems.

• Work across multiple data centers and contribute to a cloud-agnostic architecture that keeps systems online and scalable.

• What We're Looking For

• 3+ years in DevOps, SRE, or Platform Engineering with hands-on Kubernetes operation experience.

• Strong understanding of AWS services (EKS, DynamoDB, SNS, SQS, IAM, Lambda) and infrastructure as code with Terraform.

• Experience navigating tradeoffs between managed AWS services and open-source alternatives and know when each makes sense.

• Microservice event-driven architecture background: topics, queues, object storage; ability to support backend teams building Go services across distributed environments.

• Reliable CI/CD as a product requirement; building pipelines that are fast, predictable, and low-maintenance.

• Hands-on with emerging infrastructure; comfortable migrating workloads to self-hosted solutions and introducing new tools.

• Nice to Have

• Experience with Druid, Airflow, Spark, Trino, MLFlow, Jupiter Hub, Elasticsearch, Fluentbit, Grafana, Prometheus.

• Familiarity with cloud-agnostic architectures and open-source tooling as a deliberate choice over managed services.

• Willingness to relocate to Hamburg, Germany.

• Compensation & Benefits

• You will work on systems reaching hundreds of millions of users and billions of decisions daily.

• Grow with a diverse, global team from 40+ countries; contribute to a culture that values openness and collaboration.

• Move fast, own impactful projects, and enjoy daily wins as part of a fun, energetic team.

• Relocation support to Hamburg for those joining the team.
