About the company

Company is a forefront of technological advancement, integrating cutting-edge solutions into everyday life. Our culture thrives on innovation, collaboration, and a commitment to excellence. We foster an inclusive environment where every team member's contribution is valued and where everyone has the opportunity to grow.

About the job

• Conduct proactive offensive security testing and attack validation across public-facing Web, API, mobile, cloud and infrastructure environments. Identify realistic and exploitable attack paths and drive remediation to closure.
• Perform penetration testing, vulnerability validation and red/blue security exercises, going beyond automated vulnerability scanning to understand how weaknesses can be exploited in real-world scenarios.
• Run security monitoring, alert triage, investigation and severity classification (P0–P3) using our SIEM environment (Alibaba Cloud Threat Analysis / Agentic SOC + SLS).
• Develop and tune detection rules to improve coverage of key threats such as account takeover, automated attacks, credential or secret leakage, privilege misuse, ransomware and business-logic abuse, while continuously reducing false positives.
• Translate identified attack techniques and vulnerabilities into practical detection, prevention and response controls.
• Lead end-to-end Incident Response, including detection → investigation → containment → eradication → recovery → post-mortem, with clear written incident reports.
• Develop SOAR and security automation playbooks, preferably using Go, to automate repetitive response activities such as auto-blocking, isolation, credential handling and security enrichment.
• Aggregate security logs across multiple platforms (Alibaba Cloud primary + AWS + Tencent Cloud + Cloudflare) into the SIEM for unified monitoring and analysis.
• Operate and optimize native cloud and platform security capabilities such as Cloud Security Center, GuardDuty, WAF and other security controls

Requirements

• Bachelor's degree in Computer Science, Cybersecurity, Information Technology, Engineering or a related field, or equivalent practical experience.
• 3+ years of hands-on cybersecurity experience, including Security Operations, Incident Response, Product/Application Security or Offensive Security.
• Hands-on Offensive Security experience is required, including practical experience in penetration testing, attack simulation or vulnerability exploitation.
• Able to independently perform security testing against Web applications and APIs, identify realistic attack paths and validate vulnerabilities beyond automated scanner results.
• Ability to develop PoCs, scripts or exploit scenarios to demonstrate and validate security weaknesses.
• Familiarity with the security stack of at least one major public cloud platform such as Alibaba Cloud, AWS or Tencent Cloud.
