About the team
We are looking for curious, driven individuals passionate about enhancing security maturity through attack to join us as a Lead Security Engineer for our Offensive Security team.

By simulating real-world attacks, we strengthen our security posture and continuously evolve our defense strategies to stay ahead of adversaries.
Your role will be key in helping teams across Nubank understand and collaborate with Offensive Security initiatives. You'll work closely with security engineers, product teams, and other stakeholders to educate, guide, and support them in implementing secure development practices, ensuring that security is embedded into our products and services from the ground up.
This is an exciting opportunity to play a pivotal role in enhancing Nubank's security maturity. You will be key in creating resources, providing guidance, and advocating for best practices to help teams proactively identify and address security risks, ultimately protecting our customers and the company from emerging threats.

- Perform infrastructure, web, and mobile/API pentest;
- Craft and execute red team operations;
- Help with vulnerability management;
- Code tools that assist with offensive security reviews;
- Support operations to fix vulnerabilities and help development squads to understand security issues;
- Assist in architectural / logical reviews of different softwares.
What are we looking for?
- Offensive Security background, with a focus on Red Team activities;
- Experience with different parts of a pentest, such as reconnaissance, enumeration, exploitation, post-exploitation, lateral movement, etc;
- Strong knowledge of recent and past attack vectors, as well as exploitations, and how to fix them;
- Ability to reproduce behavior of Advanced Persistent Threat (APTs) groups;
- Experience with security frameworks, such as OWASP;
- Familiarity with AWS general concepts;

Familiarity with Nmap, Metasploit, SQLmap, Nessus, Censys, Shodan, and Frida.re is also valuable. More broadly, proficiency with any tool that aids in assessing and validating security is highly desirable.
