Senior IAM

MongoDB’s mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data. We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, MongoDB Atlas, is the only globally distributed, multi-cloud database and is available in more than 115 regions across AWS, Google Cloud, and Microsoft Azure. Atlas allows customers to build and run applications anywhere—on premises, or across cloud providers. With offices worldwide and over 175,000 new developers signing up to use MongoDB every month, it’s no wonder that leading organizations, like Samsung and Toyota, trust MongoDB to build next-generation, AI-powered applications.

We are seeking a highly experienced Senior IAM & Security Engineer with deep expertise in IAM, cloud security, automation, and endpoint security. In this role, you will lead the design, implementation, and ongoing management of complex security solutions at scale while partnering closely with cross-functional teams to strengthen our security posture and streamline secure access across our global environment.
