About the Opportunity

This opportunity focuses on supporting the development and iteration of the DevSecOps DAST scanning engine within security products, with a goal of enhancing scanning efficiency, detection rates, and coverage. You will analyze the scope and priority of identified vulnerabilities, develop and optimize scanning and suppression rules, and ensure accurate and reliable detection. Additionally, you will play a key role in governing existing business operations to strengthen security management and drive continuous improvement.

What You’ll Be Doing

• Develop and maintain the DevSecOps DAST scanning engine.
• Write and optimize DAST scanning rules based on complex application scenarios, verify vulnerabilities identified by the DAST scanning engine, and ensure the accuracy of vulnerability scanning and reproduction.
• Analyze the scope and priority of identified vulnerabilities, formulate false positive suppression rules, and improve the accuracy of vulnerability identification.
• Continuously iterate the DAST engine, optimize the scanning process, improve scanning efficiency and detection rate, and enhance scanning coverage.
• Collaborate with development, operations, and security teams to support vulnerability remediation and security improvements, providing recommendations for security hardening.
• Provide technical support and training to team members, promoting best practices in security governance.
