About the team and the role: 

The eBay Cloud Core Services team powers the foundational cloud infrastructure that supports thousands of eBay applications. As one of the largest private cloud platforms in the industry, we operate and manage hundreds of Kubernetes clusters across diverse environments, comprising millions of compute instances.

Our team is responsible for the full lifecycle management of these clusters—including provisioning, OS and Kubernetes upgrades, technical refreshes, and decommissioning. We also customize the Linux operating system for our Kubernetes platform, enhancing the kernel to meet eBay’s rigorous scalability, reliability, and security requirements.

The ideal candidate will have at least 8 years of experience in the field, focusing on kernel development and cluster automation(build, os/kubernetes upgrade and decommission). You will also drive the implementation of observability practices to monitor, troubleshoot, and ensure the reliability of our infrastructure at scale.

What you will accomplish: 

• Design, develop, and maintain a stable, high-performance Linux operating system optimized for the Kubernetes platform, along with the supporting cluster management system.

• Contribute to kernel development and performance tuning to enhance system scalability, reliability, and efficiency; stay up to date with the latest advancements in kernel and security technologies.

• Build high-performance tools and services using Go and Python to support infrastructure automation and diagnostics.

• Develop BPF-based tools for in-depth OS diagnostics and implement Cilium/BPF-based network segmentation and service mesh solutions.

• Champion engineering excellence in observability, security, and performance across the platform, ensuring systems meet eBay's production standards.

• Influence adoption of optimized solutions across functional teams, driving consensus and backing technical decisions that align with business goals.

• Mentor team members and multiply team effectiveness through code reviews, technical guidance, and evangelizing productivity improvements.

What you will bring: 

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.

• 8+ years of hands-on experience with Linux systems, with deep expertise in kernel development and OS internals (process scheduling, memory management, file systems, networking).

• Proficient in programming with C++, Go, or Python.

• Proven track record of owning large functional areas in container orchestration and building production-grade cluster management systems at scale.

• Demonstrated leadership in mentoring team members, setting technical standards, and collaborating across teams to deliver measurable business impact.

• Strong ability to identify cross-functional gaps, express technical risks/tradeoffs, influence decisions, and drive end-to-end resolution.
