TikTok dominates the global short video space — but when it comes to AI, we're just getting started. There's still massive room for innovation. Yet today, applying AI technology at scale inside TikTok remains difficult — fragmented tools, high technical barriers, and limited collaboration slow down innovation. We're changing that.
Join us to accelerate the adoption of AI across TikTok. Our mission is to democratize AI through a powerful platform that lowers the barrier to entry, empowers non-technical roles, and enables fast, reliable iteration. Our business covers a wide range of areas, including content governance, PGC, local services, livestreaming, music, etc.

We are looking for talented individuals to join our AI Platform team for an internship in 2025 to be based in San Jose. In this role, you'll work closely with product and algorithm teams across TikTok to build the infrastructure that powers agile model iteration and brings AI into every corner of the business.

Internships at TikTok aim to provide students with hands-on experience in developing fundamental skills and exploring potential career paths. A vibrant blend of social events and enriching development workshops will be available for you to explore. Here, you will utilize your knowledge in real-world scenarios while laying a strong foundation for personal and professional growth.

Applications will be reviewed on a rolling basis - we encourage you to apply early.
Successful candidates must be able to commit to at least 12-week long internship period.

As a member of TikTok PGG AI Platform team, you will:
- Responsible for developing our AI Platform by using cutting-edge AI technologies such as LLM, MLLM, RAG, and Agents.
- Work closely with product managers, algorithm teams, and other cross-functional stakeholders to tackle complex, high-impact problems.
- Design and evolve system architecture to ensure scalability, performance, and reliability. Build robust infrastructure to integrate LLM capabilities into real-world business applications.
