About the team
The TikTok AI&Visual Search Infrastructure team builds systems that power intelligent search experiences for users around the world. Our infrastructure serves billions of search requests every day and supports products including traditional search, AI-powered search results, in-app chatbots, and visual search.
Our work spans both foundational search engine infrastructure and the rapidly evolving AI Search technology stack. We build large-scale indexing and retrieval systems, multimodal search infrastructure, multi-agent and RAG engines, and high-performance LLM/VLM training and serving platforms.
As an engineer on the team, you will have the opportunity to work on challenging problems across AI Agents, RAG, LLM/VLM inference/training, distributed systems, search engines and multimodal machine learning. You will collaborate closely with engineers, researchers, and product teams to help shape the next generation of TikTok Search.
We embrace a culture of self-direction, intellectual curiosity, openness, and problem-solving.

We are looking for talented individuals to join us for an internship. Our internship program offers students hands-on experience, industry exposure, and opportunities to apply their knowledge to real-world challenges while building a strong foundation for personal and professional growth.
Interns will gain practical experience, explore potential career paths, and participate in social events, learning programs, and development workshops alongside industry professionals.
Candidates may apply to a maximum of two positions across Our Company and its affiliates globally. Applications will be considered in the order they are submitted.
Applications are reviewed on a rolling basis, so we encourage you to apply early. Please clearly state your availability in your resume, including your start and end dates.

Candidates who pass resume screening will be invited to participate in Our Company's technical online assessment.

- Deploy and optimize LLM/VLM post-training and inference, including GPU inference acceleration, SFT/RL efficiency, kernel/CUDA optimizations, and offline throughput improvement.
- Build and improve search engine components such as offline document processing pipelines, distributed indexing systems for billion/trillion documents, feature extraction services, and multi-stage retrieval/ranking services
- Develop scalable data pipelines and distributed systems for processing billion- or trillion-scale text, image, and video datasets, covering offline computation, stream processing, task scheduling, storage, and data quality.
- Explore emerging technologies in personalized search, generative search, multimodal understanding, reinforcement learning, model alignment, and evaluation.
