Enterprise Cloud under Global Infrastructure is seeking a highly experienced Senior Multi-Cloud Network Engineer to design, build, secure, automate, and operate enterprise-scale cloud network fabrics across Amazon Web Services (AWS) and Google Cloud Platform (GCP).
The ideal candidate will have deep hands-on experience building complex cloud network architectures across both AWS and GCP, including multi-account/multi-project environments, hybrid connectivity, inter-cloud connectivity, network segmentation, routing, DNS, traffic inspection, and centralized security controls. This role requires strong foundational networking expertise combined with practical knowledge of how AWS and GCP implement networking differently.
The successful candidate will design cloud networks that are secure by design, highly available, scalable, observable, automated, and resilient, applying least privilege, Zero Trust, defense-in-depth, segmentation, and policy-driven infrastructure principles.
