Streaming Reliability Engineer

Streaming Reliability EngineerStockholm, Sweden — HybridMobility Technology | Streaming Infrastructure | Site Reliability Engineering | Real-Time Data | Distributed Systems Our client, a growing Mobility Technology company based in Stockholm, is looking for a Streaming Reliability Engineer to own the performance, resilience, and operability of high-throughput streaming infrastructure processing real-time operational data. You'll work at the intersection of Streaming Engineering, SRE, and Platform Engineering, ensuring Kafka and Flink workloads remain fast, observable, and reliable as data volumes and platform complexity grow. What You'll Work On• Operate and improve high-throughput Kafka infrastructure• Build and optimise real-time processing workloads using Apache Flink• Improve reliability across Kubernetes-based streaming environments• Define SLIs, SLOs, and reliability standards for critical streaming services• Build monitoring and alerting using Prometheus• Investigate latency, throughput, consumer lag, backpressure, and processing failures• Automate infrastructure provisioning and configuration using Terraform• Improve partitioning, scaling, and resource-allocation strategies• Build reliability tooling in Java and/or Scala• Automate recovery and reduce manual intervention during incidents• Perform capacity planning for growing event volumes• Partner with Data and Platform Engineers to design more resilient streaming systems Core Skills• 4+ years in Streaming Engineering, SRE, Data Infrastructure, Platform Engineering, or similar roles• Apache Kafka• Apache Flink• Kubernetes• Java and/or Scala• Prometheus• Terraform• Strong understanding of distributed systems and production reliability Nice to HaveKafka Streams / Kafka ConnectSchema Registry / Avro / ProtobufGrafana / OpenTelemetryExactly-once processing conceptsEvent-driven architecturesAWS / GCPGitOps / Argo CDJVM performance tuningIncident management and postmortemsHigh-throughput or low-latency systemsExperience operating multi-region streaming infrastructure
