The Business Risk Integrated Control (BRIC) team is missioned:
- To protect TikTok users, including and beyond content consumers, creators, advertisers;
- By securing platform health and community experience authenticity;
- Through building infrastructures, platforms and technologies, as well as to collaborate with many cross-functional teams and stakeholders.
The BRIC team works to minimise the damage of inauthentic behaviours on TikTok, covering multiple classical and novel community and business risk areas such as account integrity, engagement authenticity, anti spam, API and growth health, live streaming security and financial safety (ads or e-commerce), etc.

The work needs to be fast, transferrable, while still down to the ground to making quick and solid differences.
