Ciam Engineer Jobs in New York (NOW HIRING)

The Senior IAM Engineer is the technical anchor of the Customer IAM team. Where the IAM Engineer executes established patterns, the Senior Engineer defines them. You own the platform architecture, author the standards that every integration must meet, design the automation that keeps configuration consistent at scale, and provide the technical leadership that enables your teammates and application development teams to move faster and more securely.

You operate with broad autonomy, making consequential decisions on Customer Identity Engine configuration, authentication policy design, IaC strategy, and security control architecture - while staying closely partnered with the Manager on roadmap direction and cross-functional relationships. This is a senior individual contributor role with significant influence over the team's technical trajectory.
