• Experience performing deep debugging of tools to fix memory leaks, race conditions and others.

• Familiarity with Docker, Git, and K8s. You adhere to high code quality standards and unit testing practices.

• Participation in CTFs/Bug Bounties is necessary, certifications like OSCP, OSWE, or equivalent certifications are a major plus.
