About the team and the role:
As a Capacity Planning Engineer at eBay, you will play a vital role in influencing the financial architecture of our ecommerce platform. You will partner with platform, engineering, search, product, data center, supply chain, and network teams to plan capacity across hybrid environments, including on-premises Kubernetes, Azure, and GCP. This is an outstanding opportunity to lead the charge in optimizing our resource management and ensuring flawless operations across our engineering stack.
The role focuses on forecasting infrastructure demand, improving resource efficiency, and ensuring compute, storage, and network capacity can support traffic growth, new capabilities, and business continuity requirements. You will also contribute to capacity tooling, observability, automation, and analysis across large-scale distributed environments.
What you will accomplish:
- Develop and execute capacity plans across on-premises Kubernetes, Azure, and GCP environments.
- Partner with AI, Hadoop, Spark, MapReduce, HDFS, Search, and other platform teams to translate workload characteristics, traffic growth, indexing needs, and sizing requirements into capacity plans.
- Analyze infrastructure demand, utilization, and performance to forecast capacity needs and optimize compute, storage, and network resource allocation.
- Identify performance bottlenecks and underused resources, and drive improvements in efficiency, cost, availability, and reliability.
- Build dashboards and observability solutions using tools such as Grafana and Prometheus, and provide reporting on capacity status, forecasts, trends, and optimization opportunities.
- Conduct scenario and “what-if” modeling to assess the impact of traffic growth, new features, and infrastructure changes.
- Contribute to capacity planning automation, performance analysis, workload optimization, root cause analysis, and improvements to capacity engineering processes and methodologies.
