About this role

Offensive Security Engineer São Paulo About the Role This is not a traditional pentesting role. At CloudWalk, you'll go beyond running scans or writing reports. You'll break into systems, exploit real weaknesses, and then engineer automations and agents to make sure those classes of vulnerabilities never come back. Your work will directly shape how CloudWalk defends itself at scale, turning offensive security knowledge into defensive engineering. You'll be part of a team that blends red teaming, mobile/web pentesting, and security automation. If you enjoy moving fast, exploiting hard problems, and coding the solutions, this role is for you.
