Senior Security Lead in Ho Chi Minh City, Vietnam at ZALORA SOUTH EAST ASIA PTE LTD

ZALORA is Asia’s leading online fashion, beauty and lifestyle destination, part of Global Fashion Group. As one of the region’s pioneer large scale e-commerce platforms, ZALORA has established a strong presence throughout the region, particularly in Singapore, Indonesia, Malaysia, Brunei, the Philippines, and Hong Kong, enjoying over 50 million visits per month.

ABOUT THE ROLE

Zalora, one of GFG’s e-commerce platforms, is hiring a security leader to build and run day-to-day security for Zalora — leading, staffing, and prioritizing the work of a small security team, in close collaboration with GFG’s group-level security function. This is a “player-coach” role: you align with the Group CISO’s overall security strategy, but you own how that strategy gets executed for Zalora, staying hands-on where it matters — reviewing architectures, hardening cloud environments, and acting as the senior technical escalation point when incidents happen.

You’ll work closely with Zalora engineering and business stakeholders to keep secure-by-design practices in place, including for AI/LLM features, while managing Zalora’s security team and coordinating external specialist consultants when needed.

WHAT WILL YOU DO

Team Leadership & Stakeholder Management

• Lead, mentor, and grow Zalora’s security team — set priorities, review work, and develop team members’ skills.
• Own hiring and resourcing input for the team, including when to bring in external specialist consultants versus building in-house capability.
• Act as the primary point of contact between security and Zalora business/engineering leadership, translating security risk into business terms and negotiating trade-offs.
• Represent Zalora’s security posture and priorities in group-level conversations with the Global CISO organization.

Hands-On Security Engineering

• Execute security architecture reviews for new and existing systems, and validate cloud security posture (primarily AWS, also GCP).
• Implement and maintain IAM strategies, zero trus t controls, and infrastructure-as-code security.
• Integrate security automation into CI/CD pipelines and DevSecOps workflows.
• Secure containerized environments (Docker, Kubernetes).

Application & AI/LLM Security

• Run threat modeling, SAST/DAST, and mobile application security testing on key systems.
• Review AI-driven features and LLM integrations for risks such as prompt injection, data leakage, and supply chain vulnerabilities, and recommend concrete mitigations.
• Apply existing AI/LLM security standards (e.g., OWASP Top 10 for LLM Applications) to real reviews, rather than authoring group-wide policy.

Incident Response, Testing & Team Coordination

• Act as the senior technical escalation point during active incidents, leading technical response and remediation.
• Run penetration testing and red-team exercises (internally or via external consultants), and track findings through to fix.
• Manage relationships with external vendors and specialist consultants for pentesting, AI security, and peak-demand coverage.

WHAT WE ARE LOOKING FOR

General qualifications

• 7–10+ years of hands-on experience in security engineering, product security, or infrastructure security (not purely strategy/GRC roles).
• Comfortable being the technical decision-maker under pressure — e.g., during a live incident or a contested architecture review.
• Able to explain a technical finding (e.g., a vulnerability or misconfiguration) clearly to a non-technical stakeholder.
• Experience leading or building a security team — direct people-management experience preferred, technical/task leadership of a team at minimum.
• Experience in fashion or retail e-commerce is a plus, not required.

Technical Expertise

• Strong, hands-on AWS security experience (IAM, network security, security services); working knowledge of GCP.
• Practical experience with SAST/DAST tooling, threat modeling, and mobile application security testing.
• Working knowledge of AI/ML security risks and frameworks (OWASP Top 10 for LLM Applications, NIST AI RMF), with real experience reviewing LLM-integrated features or third-party AI tools.
• Experience securing containerized environments (Docker, Kubernetes) and CI/CD pipelines.
• Comfortable running or supporting penetration tests and red-team exercises, including remediation follow-through.

Team & Collaboration

• Track record of giving technical guidance and unblocking engineers day-to-day, as well as managing team performance and development — not just high-level mentorship.
• Able to work with engineering and business stakeholders, including senior leadership, to get security fixes prioritized, shipped, and communicated in business terms.
• Comfortable balancing GFG group-level security standards with Zalora’s local regulatory needs across its markets.
