The Observability Platform team builds and operates the infrastructure that helps eBay teams monitor, troubleshoot, and improve the reliability of large-scale distributed systems. The platform supports the telemetry and reliability needs of thousands of microservices across eBay and operates at hyperscale, processing billions of time series and petabytes of log data using modern open-source technologies such as Prometheus, Click House, Open Telemetry, and related tools.

As a Senior Software Engineer on this team, you will design and build high-performance distributed systems in Golang that power eBay’s observability platform across metrics, logs, traces, and related workflows. You will work across the full telemetry lifecycle—from ingestion and processing to storage, query, and platform services—building reliable backend systems that operate at massive scale.

You will partner closely with SREs, platform engineers, and service owners to solve complex reliability challenges, improve operational excellence, and help shape the future of observability s role offers the opportunity to work on business-critical infrastructure, contribute to open-source technologies, and grow through direct exposure to some of eBay’s most complex engineering problems. This role also includes participation in the team’s on-call rotation in support of production reliability.
