OverviewJoin New Relic to architect, build, and run high-scale JVM-based microservices that ingest and analyze massive telemetry data for an observability platform.

You will own services end-to-end, optimize for performance and reliability, and contribute to deep observability and incident response in a fast-growing, AI-first environment.

You'll work with cross-functional teams to deliver reliable customer outcomes and advance our mission to empower engineering teams with real-time insight.

fully office-based, fully remote, or hybrid options

ResponsabilidadesDesign, build, and operate JVM-based microservices (Java/Kotlin) with emphasis on performance and scalability

Own services end-to-end including architecture, deployment, monitoring, on-call participation, and continuous improvement

Apply concurrency and performance practices: asynchronous programming, backpressure, efficient I/O, memory management, GC tuning

Build and evolve event-driven systems using Kafka (streaming, partitioning, consumer groups, schema evolution)





Instrument services for observability (metrics, logs, traces), define SLIs/SLOs

Design REST/gRPC APIs and resilience patterns (timeouts, retries, circuit breakers)

Operate production services: monitoring, alerting, incident response, postmortems

Automate CI/CD, testing, and operational tasks to improve developer productivity

Collaborate with product, architecture, and cross-functional teams; Requisitos principalesStrong experience building production-grade backend services on the JVM (Java and/or Kotlin)

Hands-on experience with asynchronous/reactive programming (CompletableFuture, Project Reactor, RxJava, Kotlin coroutines)

Mentorship and leadership in reliability and performance initiatives

Java and/or Kotlin

JVM performance tuning and profiling (JFR, async-profiler, JMH)

Kafka and streaming patterns (topic/partition strategy, idempotency, schema compatibility)
