Integrate SAST, DAST, IAST, SCA, code security scanning, and image security scanning into CI/CD workflows; integrate tools such as SonarQube and Coverity for scanning, gating, remediation, and re-validation.
Drive application security protection and offensive/defensive capabilities for XSS, SQL injection, SSRF, deserialization, command execution, authentication and authorization flaws, privilege escalation, and API security.
Apply LLMs and AI Agents to vulnerability analysis, rule generation, false-positive reduction, remediation suggestions, security knowledge management, and workflow automation, while building understanding of their architecture, principles, and security implications.
Partner with business engineering teams to drive security standards, integration rules, quality gates, risk classification, remediation workflows, and security governance adoption.
Collaborate with engineering, architecture, operations, QA, and business stakeholders to solve security problems and turn them into scalable product capabilities, engineering solutions, and governance mechanisms.

Desired Qualifications

Background at top-tier Internet companies, cloud providers, or leading cybersecurity vendors.
Experience leading DevSecOps platforms, application security platforms, RASP systems, code scanning platforms, or cloud-native security platforms.
Experience in security product development, SDK/Agent development, vulnerability research, penetration testing, red/blue team exercises, or incident response.
