Staff Security Engineer (IAM)

Nu is seeking a Staff Security Engineer to contribute in the Identity and Access Management security function across a financial technology organization serving over 100 million customers in Brazil, Mexico, and Colombia. This is a senior individual-contributor role with organizational-level technical influence, responsible for supporting a multi-year IAM security strategy, directing its execution across multiple engineering teams, and ensuring that identity and access controls meet the security, regulatory, and operational requirements of a globally operating financial institution.

The Staff Security Engineer is expected to bring a demonstrated history of delivering consequential security programs — including programs that encountered setbacks — and the technical judgment that only sustained, hands-on experience in the domain produces. Critically, this role requires a security engineering philosophy grounded in business enablement: the conviction that security done well accelerates what the organization can do, not merely protects it.
