Trust is one of TikTok's biggest initiatives, and security is integral to our success. In whatever ways users interact with us — whether they're watching videos on their For You page, interacting with a Live video, or buying products on TikTok Shop — GSO protects their data and privacy, so they can have a secure and trustworthy experience.
The Enterprise to Edge security team, part of the SecOps Validation Team (STOV) is responsible for the tools and technologies that support the TikTok infrastructure. STOV oversees technical validation, security operations, and drives engineering enhancements, including the deployment, configuration, and maintenance of security technologies across various domains.
This role is responsible for the design and development of security architecture and the implementation of technical controls, and validating them in alignment with security policies and regulatory requirements. Key validation areas include enterprise security at TikTok and securing the full-stack security lifecycle. This position plays a critical role in establishing a foundational framework to assess and advance the maturity of TikTok’s security architecture. The role will also maintain and evolve security architectures across enterprise systems, endpoints, cloud, email infrastructure, data centers, networks, and CDN environments, enabling continuous validation and enhancement of security maturity.

Responsibilities

• Own security architecture and control frameworks across self-built data centers, OCI, AWS, Azure, and GCP in hybrid/multi-cloud environments.
• Implement defense-in-depth controls across IaaS, PaaS, containers, and IAM for infrastructure.
• Lead threat modeling and architecture reviews to identify and mitigate risks before production.
• Embed automated security scanning, policy-as-code, and approval gates into CI/CD pipelines.
• Build scalable IaC frameworks to enforce security baselines and eliminate configuration drift.
• Partner with engineering, infrastructure, and business teams to shift security left in the design lifecycle.
• Drive control maturity through regular assessments and a roadmap focused on automation and operational efficiency.
• Design and mature cloud network security controls - including VPC architecture, micro-segmentation, and firewall policies, and establish centralized security logging and audit trail coverage.

Qualifications

Minimum Qualifications:

• Proven expertise in designing and implementing security controls across Hybrid and Multi-Cloud environments (e.g., Data Centers, AWS, Azure, GCP, OCI).
