About the Team Byte Dance 's Global Engineering CDN team builds and operates a highly available, cost-efficient, and high-performance global multi-cloud CDN platform that powers large-scale products such as Tik Tok.

Our platform integrates both self-built CDN infrastructure and commercial CDN vendors across multiple regions worldwide, delivering reliable and optimized content delivery for diverse global markets. The team develops and operates core platform capabilities including domain onboarding and configuration management, content management, data analytics, and global traffic optimization.
