About The Position

Walmart Global Tech is seeking a System and Infrastructure Engineer III within Information Security, specializing in Access Management Engineering (AME). This role focuses on building, operating, and improving the access control foundations that protect Walmart’s enterprise systems at global scale. As part of the AME team, you will design and engineer identity and access management (IAM) capabilities that enable secure, compliant, and efficient access for associates, applications, and services across corporate, retail, supply chain, cloud, and legacy environments. This is a hands‑on engineering role that blends software engineering, systems engineering, and security. You will work directly with platforms such as Active Directory, Entra ID (Azure AD), SailPoint, ServiceNow, and enterprise authorization systems, helping ensure access is provisioned correctly, removed promptly, audited continuously, and automated wherever possible. You will partner closely with application teams, infrastructure teams, IAM platform teams, and security stakeholders to embed access controls into real business workflows—not just design them on paper.
