We’re seeking a passionate and experienced Software Engineer focused on distributed systems to join our Observability Platform team. In this pivotal role, you will design and build scalable infrastructure that powers the telemetry, monitoring, and reliability needs of our platform teams. Our Observability platform is a hyperscaler, operating on billions of time series and petabytes of logs, and is completely built on cutting-edge open-source technologies such as Prometheus, ClickHouse, OpenTelemetry, and more. You will work across the stack – from data ingestion and storage to visualization – to ensure we build systems that are reliable, performant, and a joy to use.

You will partner closely with world-class SREs, platform engineers, and service owners to support the development, scaling, and maintenance of mission-critical observability systems that power modern, high-scale distributed applications. Working with this team unlocks unparalleled exposure to SREs who manage eBay's site, comprising thousands of microservices. You'll be at the bleeding edge, solving observability problems that are not even a concern for most yet, contribute to open-source projects, and gain an invaluable learning experience.

Build and optimize services for ingesting, transforming, and querying telemetry data such as logs, metrics, and traces

Operate production-grade Kubernetes-based systems with a focus on self-healing, autoscaling, and robustness

Collaborate across teams to understand observability needs and build tools that enhance operational excellence

Contribute to system design reviews and post-incident retrospectives with a mindset of continuous improvement

Participate in the team’s site on-call rotation to help ensure the availability and reliability of our observability systems
