Security Operations Engineer

Key Responsibilities

• Security Event Monitoring & SIEM Administration
  Monitor security alerts across hybrid environments (on-prem, cloud, IDC). Maintain, tune, and optimize SIEM detection rules to reduce false positives and improve threat detection accuracy.

• Incident Response Support
  Execute end-to-end incident response: containment, eradication, recovery, and post-incident reporting. Collaborate with IT, DevOps, and app security teams to implement long-term fixes.

• Cloud & Infrastructure Security Review
  Evaluate cloud security configurations (security groups, firewalls, IDS/IPS, AK/SK strategies). Identify misconfigurations and high-risk attack paths in cloud and internal networks.

• Threat Analysis & Response Planning
  Track emerging threats, APT techniques, and black-market ecosystems. Translate threat intelligence into detection rules and response playbooks.

• Documentation & Coordination
  Maintain incident response frameworks, run security drills, and provide clear recommendations to improve the company's security posture.

What You Bring

• 5+ years of hands-on security experience (SOC, threat detection, red/blue, or IR).
• SIEM expertise - you've built, optimized, and operated detection rules at scale.
• Cloud security - you know how attackers abuse cloud misconfigurations and how to fix them.
• Offensive mindset - you've done penetration testing, red-team exercises, or APT-style simulations.
• Incident response - you've led or supported real-world intrusion investigations.
• Development skills (Python, Go, C, React) - you can read code, audit for vulnerabilities, or build internal tools.
• Deep understanding of TCP/IP, enterprise networking, zero-trust, and internal network penetration.
• Experience in financial, government, or gaming sectors is a strong plus.
• Language Requirement: Fluency in Mandarin (spoken and written) is mandatory. The incumbent must be able to understand, communicate, and reply in Chinese, as the role involves close daily collaboration with clients in China.
