Leads cloud infrastructure and platform engineering teams responsible for large-scale private cloud and Kubernetes environments. Develops cloud platform strategy, drives reliability, automation, observability, self-service infrastructure, GitOps, and SRE practices. Partners across engineering, security, networking, and product teams to deliver resilient platforms. Promotes AI-assisted operational tooling, developer productivity, inclusive team development, and continuous improvement across globally distributed engineering organizations.

Design, build, and operate scalable control-plane services and Kubernetes controllers enforcing network segmentation and security policies across clusters, clouds, and data centers. Integrate cloud-native networking (CNI, service mesh), automate policy lifecycle, lead production troubleshooting, apply CI/CD and observability, mentor engineers, and use AI tools to accelerate development and operations.

Design and build cloud-scale directory services, authorization platforms, and policy engines. Develop scalable APIs and microservices, implement RBAC/ABAC/PBAC models, write production-ready code with CI/CD and observability, troubleshoot production issues, collaborate across Identity, Platform, Security, and Infrastructure, and adopt AI-assisted tools to automate and improve engineering productivity.

Develop and maintain high-performance Linux operating systems and Kubernetes cluster management systems at scale. Responsibilities include kernel development, performance tuning, infrastructure automation with Go and Python, BPF-based diagnostics, Cilium network segmentation, service mesh solutions, and observability implementation. The role also involves cross-functional collaboration, troubleshooting, and mentoring.

Design, build, and maintain scalable backend services for eBay's Cloud Security Segmentation platform. Develop Kubernetes-based control plane services, troubleshoot distributed systems and cloud infrastructure, use CI/CD and automated testing, participate in code reviews and incident response, and leverage AI-assisted engineering tools to improve productivity and reliability.

Design, build, and manage cloud-native platform tools supporting the full application lifecycle on eBay’s private cloud. Responsibilities include developing UIs, CLIs, automation and diagnostic tools in Go and Java, integrating Kubernetes and open-source technologies, improving CI/CD and developer productivity, ensuring security compliance, and deploying observability frameworks. The role also involves cross-functional collaboration, platform adoption, issue resolution, and mentoring.

Design, build, and maintain a high-performance Kubernetes fleet management system; contribute to Linux kernel development and tuning; develop automation and diagnostic tools in Go/Python/C++; integrate optimized OS distributions; and implement observability frameworks to ensure reliability and scalability across millions of instances.

Design and build cloud-scale identity and authorization services, high-performance policy engines, and secure microservices. Integrate AI-assisted engineering and AI-driven capabilities to improve policy intelligence, anomaly detection, and operational automation. Partner across Identity, Platform, Security, and Infrastructure to ensure scalability, reliability, observability, and secure real-time access decisions.

Design, build, and operate production systems (Python/Java/SQL) that detect, investigate, and disrupt cybercrime. Develop AI-native, agentic workflows, services, and pipelines, own end-to-end delivery, and translate attacker research into scalable protections.
