The Systems and Networking team is committed to ensuring the seamless operation of TikTok's US physical infrastructure. We handle the provisioning of physical servers and maintain the TikTok US physical network. Additionally, we engage in collaborative efforts with vendors such as OCI and Akamai to manage physical hardware, networks, and uphold assurance and compliance objectives. We also work closely with our colleagues around the world to build and support various platforms within our US region, including internal platforms that support our daily operations. Our primary goal is to ensure the uninterrupted functionality of TikTok's US Physical Infrastructure, thus facilitating other internal middleware teams to deliver essential intermediary services to internal business units such as Product, e-Commerce, Ads/Monetization, etc., all while strictly adhering to compliance standards. In order to enhance collaboration and cross-functional partnerships, among other things, at this time, our organization follows a hybrid work schedule that requires employees to work in the office 3 days a week, or as directed by their manager/department. We regularly review our hybrid work model, and the specific requirements may change at any time.
