Descripción de la vacante

New Relic is seeking a backend engineer to design, build, and operate JVM-based microservices (Java/Kotlin) powering massive telemetry pipelines and observability features. You will own services end-to-end, implement asynchronous patterns, and contribute to a scalable, resilient platform used by engineers globally.

The role emphasizes strong collaboration, production readiness, and mentorship in reliability initiatives, with a flexible work model including hybrid, remote, or office-based

Formación

• Production-grade backend services on the JVM (Java/Kotlin).
• Distributed systems concepts (consistency, partitioning, replication).
• Asynchronous and reactive programming (CompletableFuture, Reactor, RxJava, Kotlin coroutines).
• Experience with Kafka and streaming architectures.
• REST/gRPC API design and service-to-service communication.
• Containers, Kubernetes, and CI/CD pipelines.
• Production operations: monitoring, alerting, incident response.
• Strong written and verbal communication; design docs and collaboration.
• Mentorship or leadership in reliability and performance initiatives.

Responsabilidades

• Design, build, and operate JVM-based microservices (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, GC tuning.
• Build and evolve event-driven systems; work with Kafka for streaming, partitioning, consumer groups, and schema evolution.
• Experience with Kafka or similar streaming technologies (topic/partition strategy, consumer lag, idempotency, schema compatibility).
• Proficiency with REST/gRPC API design, service-to-service communication, and resilience patterns.
• Practical experience with containers and Kubernetes, and with CI/CD pipelines.
• Track record of operating services in production: monitoring, alerting, incident response, postmortems.
• Strong communication skills, ability to write design docs, and collaborate across teams; proficiency in error budgets to drive reliability.
• Automate CI/CD, testing, and operational tasks; improve developer productivity with tooling and infrastructure as code.
• Collaborate with product, architecture, and cross-functional partners to deliver customer outcomes.
• Mentor peers, review designs and code, and contribute to technical standards and best practices.

We are a global team of innovators and pioneers dedicated to shaping the future of observability. At New Relic, we build an intelligent platform that empowers companies to thrive in an AI-first world by giving them unparalleled insight into their complex systems. As we continue to expand our global footprint, we're looking for passionate people to join our mission. If you're ready to help the world's best companies optimize their digital applications, we invite you to explore a career with us!

We are a global team of innovators shaping the future of observability. Our intelligent platform gives customers real-time insight into complex systems so they can innovate faster and operate reliably in an AI-first world. If you’re excited by high-throughput distributed systems and want to contribute to one of the largest and fastest-growing observability platforms, we’d love to hear from you.

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.

Fostering a diverse, welcoming and inclusive environment is important to us. We work hard to make everyone feel comfortable bringing their best, most authentic selves to work every day. We celebrate our talented Relics' different backgrounds and abilities, and recognize the different paths they took to reach us - including nontraditional ones. Their experiences and perspectives inspire us to make our products and company the best they can be. We’re looking for people who feel connected to our mission and values, not just candidates who check off all the boxes.

If you require a reasonable accommodation to complete any part of the application or recruiting process, please reach out to [e-mail].

We believe in empowering all Relics to achieve professional and business success through a flexible workforce model. This model allows us to work in a variety of workplaces that best support our success, including fully office-based, fully remote, or hybrid.

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 collaborate across teams; proficiency in rror budgets to drive reliability.

• Automate CI/CD, testing, and operational tasks; improve developer productivity with tooling and infrastructure as code.

• Collaborate with product, architecture, and cross-functional partners to deliver customer outcomes.

• Mentor peers, review designs and code, and contribute to technical standards and best practices.

This role requires

• Strong experience building and operating production-grade backend services on the JVM (Java and/or Kotlin).

• Solid understanding of distributed systems concepts (consistency, partitioning, replication, fault tolerance) and microservice design.

• Hands-on experience with asynchronous and reactive programming (e.g., CompletableFuture, Project Reactor, RxJava, Kotlin coroutines)

Bonus points if you have

• Deep JVM performance profiling and tuning experience (JFR, async-profiler, JMH).

• Experience with schema registries and serialization formats (Avro, Protobuf), and stream processing (Kafka Streams, Flink).

• Familiarity with data stores used in observability stacks (e.g., Cassandra, Elasticsearch, Redis) and their trade-offs at scale.

• Experience with OpenTelemetry

• Prior technical mentorship or leadership in reliability and performance initiatives.
