Information about the position 

As a Senior Site Reliability Engineer II on the Kafka team, you'll build and operate the software and infrastructure behind one of Vinted's busiest platforms. The Kafka platform spans multiple data centers and regions across the EU and US, 1000+ Kafka brokers across multiple clusters.

You'll develop Kafka as a managed service, automation and client libraries, primarily using Go, Ruby and Java. You'll take ownership of solutions throughout their lifecycle: from technical design and implementation to deployment and production operation, and help shape the team's technical direction.

  • Define and own SLIs, SLOs, and error budgets for our Kafka fleet, while overseeing the health, performance, and maintenance of our clusters.
  • Tackle the realities of running high-throughput, multi-datacenter infrastructure - optimizing systems for resilience, low latency, and efficient resource utilization.
  • Participate in the on-call rotation, currently once every five to seven weeks.
  • Key Tech Stack: Storage: Ceph (RGW, RADOS) (tiered storage) with S3 API, Kubernetes persistent volumes, physical disks; Languages & Services: Go, Ruby, Java; Platform & Infra: Bare-metal Linux, Kubernetes, Docker, ArgoCD, Chef; Observability: Prometheus, Grafana, Kibana, Datadog.

  • Have hands-on experience deploying, operating, and troubleshooting services on bare metal and Kubernetes.
  • Designed and maintained distributed systems throughout their production lifecycle.
  • Understand reliability, scalability, monitoring, safe deployments, and failure recovery.
