Backend Software Engineer - Data Retention - TikTok Privacy and Security

About the job

The TikTok Privacy and Security (PnS) R&D team creates privacy solutions that are intuitive for users, auditable for regulators, and sustainable for the company, making TikTok a platform where people can safely discover, create, and connect.

We build user-facing privacy features, including privacy settings, consent management, data access and export, and age-appropriate experiences. We protect personal data across its full lifecycle, from collection and transfer through access, storage, retention, and deletion. We develop the platforms, technical controls, and governance tools behind privacy protection and regulatory compliance in global markets, and we bring privacy-enhancing technologies and research into production at scale. We tackle challenges unique to operating a platform at global scale: translating rapidly evolving laws and policies into reliable technical controls, providing transparency and auditability across highly complex data systems, supporting different regulatory requirements across regions, and making privacy protection work at the quality and speed production systems demand.

You will work across product privacy, data lifecycle management, data protection and residency, privacy engineering platforms, AI governance, and privacy-preserving technologies, using techniques including automated compliance enforcement, data lineage and taxonomy, differential privacy, trusted execution environments, AI fairness, and privacy protection for generative AI. The systems you build will protect hundreds of millions of people, and the privacy decisions you make will reach every one of them.
