  • Knowledge of web application security mechanisms and controls (e.g., SOP, CORS, CSP) (required).
  • Comprehensive understanding of common web vulnerabilities (e.g., OWASP Top 10) and their practical mitigation strategies (required).
  • Knowledge of secure system and application architecture alongside secure-by-design principles (required).
  • Practical, hands-on expertise in identifying vulnerabilities through manual security assessments and secure code reviews (required).
  • Ability to clearly articulate and explain the business impact of identified threats and vulnerabilities to developers and product teams (required).
  • A strong security-first mindset with a continuous drive to learn and achieve excellence in the cybersecurity field (required).
  • University degree in Computer Science, Information Security, or a related field (or an equivalent combination of education and practical experience) (required).
