• Have 3-5 years' experience in an application security, penetration testing, or software engineering role with a strong security focus.
• Have a strong understanding of secure SDLC and DevSecOps principles.
• Strong understanding of application security principles and common vulnerabilities (e.g., XSS, SQL Injection, Broken Access Control).
