Cloud Platform Security Engineer

Description:

The eBay Cloud team powers the core infrastructure that supports thousands of applications across the company. We run one of the world’s largest private cloud platforms built on open-source technologies, operating hundreds of Kubernetes clusters and millions of compute instances.

Our mission is to deliver end-to-end governance and lifecycle support for every eBay application running on our cloud. We’re constantly enhancing our platform’s cloud-native capabilities to ensure reliability, scalability, efficiency, and security.

We’re now looking for a Cloud Platform Security Engineer to join our team. In this role, you’ll design, implement, and manage the tools and systems that ensure security and compliance across our private cloud. You’ll focus on scalable IAM solutions, Kubernetes RBAC, and regulatory alignment (e.g., NYDFS, GDPR), working closely with global security and infrastructure teams.

What You Will Accomplish
 

• Design and maintain scalable IAM and Kubernetes RBAC solutions to govern secure access for users and services.
• Build automation and diagnostic tools in Go and Java to streamline platform operations and boost reliability.
• Partner with global security teams to embed regulatory requirements such as NYDFS and GDPR into development workflows.
• Architect observability frameworks that deliver deep visibility into application health and security posture.
• Identify and close system-level gaps to improve platform resilience and security compliance.
• Champion secure design principles and operational excellence across the cloud platform.
  
   

What You Will Bring
 

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• 5+ years of hands-on experience with Linux systems, including deep knowledge of kernel internals (scheduling, memory management, file systems, networking).
• Strong programming skills in C++, Go, or Python.
• Proven experience with IAM systems and Kubernetes RBAC; understanding of compliance frameworks such as GDPR and NYDFS.
• Expertise in managing containerized workloads and building scalable, secure cloud systems.
• Problem-solver with the ability to identify cross-functional issues and drive end-to-end resolutions.
• Experience mentoring others, leading small-scale initiatives, and collaborating across teams.
• Security-first mindset in both design and operations.
