Staff Software Engineer, Observability

The Observability team is responsible for deploying and maintaining critical infrastructure at CoreWeave, including our global logging, tracing, and metrics platforms as well as the high-throughput pipelines that feed them. We build the foundational telemetry systems that enable engineering teams across CoreWeave to operate our massive GPU cloud reliably and at scale.

You will take ownership of scaling our core logging, tracing, and metrics platforms to support an expanding global data centre footprint. In this role, you will develop and refine monitoring and alerting frameworks, automate interactions with CoreWeave’s compute infrastructure layer, and manage production clusters to ensure development teams follow deployment best practices. Additionally, you will advise engineers across the entire company on the optimal usage of observability systems, lead incident management and post-mortem analyses, and mentor engineers to foster a culture of technical excellence and collaboration.

• 7+ years of professional experience in Software Engineering, Site Reliability Engineering (SRE), DevOps, or a related technical field.
• Deep technical expertise across all observability pillars (logging, metrics, tracing) using ecosystem tools such as ClickHouse, Elastic, Loki, VictoriaMetrics, Prometheus, Thanos, and/or Grafana.
• Advanced expertise in Kubernetes, containerization, and microservices architectures at scale.
• Proven track record of leading production incident management, root cause analysis, and post-mortem processes.
• Strong problem-solving, analytical, and written/verbal communication skills.

• Experience running, operating, and scaling observability platforms within a cloud provider environment.
• Hands-on experience administering and operating large-scale, multi-cluster Kubernetes environments.
• Deep understanding of high-throughput data-streaming systems and telemetry ingestion pipelines.
