Nubank 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. This means rigorously distinguishing between controls that reduce real risk and those that create the appearance of compliance without reducing exposure, taking genuine ownership of outcomes rather than delegating accountability through policy, and continuously questioning inherited assumptions about what security measures are necessary, sufficient, or proportionate.
