Your opportunity Join a backend engineering team focused on building and operating JVM-based services that ingest, process, and serve massive volumes of telemetry data. You’ll work on high-scale, low-latency systems that power mission-critical observability features used by engineers worldwide.

What you’ll do
- Design, build, and operate JVM-based microservices (primarily Java and Kotlin) with a focus on performance, scalability, and reliability.
- Own services end-to-end: architecture, implementation, deployment, monitoring, on-call participation, and continuous improvement.




- Apply strong concurrency and performance practices: asynchronous programming, backpressure, efficient I/O, memory management, and GC tuning.
- Build and evolve event-driven systems; work with Kafka for streaming, partitioning, consumer groups, and schema evolution. Instrument services for deep observability (metrics, logs, traces), define SLIs/SLOs, and use e
- Experience with Kafka or similar streaming technologies (topic/partition strategy, consumer lag, idempotency, schema compatibility) strongly preferred.
- Proficiency with REST/gRPC API design, service-to-service communication, and resilience patterns (timeouts, retries, circuit breakers).
- Practical experience with containers and Kubernetes, and with CI/CD pipelines.
- Track record of operating services in production: monitoring, alerting, incident response, and postmortems.
- Strong communication skills, ability to write design docs, and colla
