About The Team:
The mission of the TikTok Eng-AI Innovation Center is to explore cutting-edge AGI technologies, including but not limited to LLM, multi-modal LLM (video/image/audio/text/code), etc., to let machine better understand user creations on Tiktok platform. Regarding to video/image/audio/text, enhanced content understanding can bring better user experience of searching, recommendation, and can more accurately identify and defend internet abuse and fraud on our platform. Regarding to code, our developed LLM aims to automatically re-organize/optimize Tiktok codebase, and make the code/coding become more accessible for Tiktok engineers.

The main job directions include:
1. Participate in the design and implementation of a high-availability, scalable, distributed large-model machine learning platform to support the development and efficient iteration of large models for TikTok;
2. Explore cutting-edge technologies related to large-model engineering(LLMOps), covering areas such as data processing, model training, inference services, evaluation system, automated orchestration, prompt engineering, and resource scheduling;
3. Construct a high-performance, cost-effective large-model inference service architecture that ensures high service availability.;
4. Explore the application of frontier large models, Code Agents, etc;
