Distinguished Engineer - Software Engineer

Position Summary...

We are seeking a Distinguished Engineer to set the technical vision and lead the architecture, engineering strategy, and execution of our proprietary Identity and Access Management (IAM) platform. This mission-critical system underpins authentication and authorization for millions of customers worldwide, processing billions of requests per day across multiple markets and countries. In this role, you will operate at enterprise scale—driving foundational design decisions that ensure the platform remains secure-by-default, highly available, resilient, and performant, even under extreme growth and evolving threat landscapes.
You will partner closely with security, infrastructure, product, and engineering leaders to modernize IAM capabilities, define reference architectures, and establish standards that influence teams across the organization. As Walmart accelerates into the AI era, you will help evolve IAM to support new interaction models, machine-to-machine identity, and policy-driven access controls—while maintaining rigorous compliance and privacy requirements. You will be accountable for advancing platform reliability and security posture, mentoring senior engineers, and delivering technology that is foundational to Walmart’s multi-billion-dollar business operations.
