Conduct authorized penetration testing for various digital platforms, including web applications, mobile applications, APIs, infrastructure, and cloud environments. Identify and document security vulnerabilities, validate and exploit when necessary, covering areas such as authentication, authorization, session management, input validation, encryption, access control, and business logic issues. Perform security assessments according to industry standards (e.g. OWASP Top 10, OWASP API Security Top 10, OWASP Mobile Security Testing Guide) and relevant security practices. Analyze application flows, user journeys, transaction processes, access controls, and data handling mechanisms to uncover potential security risks. Conduct vulnerability assessment and manual verification to reduce false positives, confirming actual exploitability in authorized environments. Retest to validate remediation effectiveness and ensure vulnerabilities are properly resolved. Support security testing activities within the software development life cycle (SDLC), including security requirement review, threat analysis, test planning, and release security validation. Stay updated with emerging cyber threats, attack techniques, security risks, and security testing best practices. Lead the planning, scoping, and execution of penetration testing activities across assigned projects. Define the penetration testing approach, test strategy, testing scope, priorities, timelines, and required evidence based on project and client requirements. Guide and mentor penetration testers or security engineers in testing methodology, vulnerability validation, reporting quality, and remediation discussions. Review vulnerability findings, risk ratings, evidence, and remediation recommendations to ensure accuracy, consistency, and practical value. Serve as the main technical point of contact for penetration testing activities, working with client stakeholders, security teams, development teams, DevOps, infrastructure teams, and compliance teams. Facilitate vulnerability walkthroughs, risk clarification sessions, remediation discussions, and retesting alignment with relevant stakeholders. Support estimation, planning, status tracking, issue escalation, and delivery reporting for security testing activities. Contribute to improving security testing processes, reporting templates, testing checklists, knowledge sharing, and reusable testing practices. Support regulatory, audit, and compliance requirements by providing security testing evidence, reports, remediation status, and technical clarification when needed.
