With the fast growth of Byte Dance's business, Byte Dance's system infrastructure is currently at a massive scale and requires versatile system solutions. Our team works on advanced R&D projects, focusing on LLM/AI + Infrastructure technologies, which includes both infrastructure for LLM/AI and LLM/AI for infrastructure. To name a few, our TextToSQL project ranks top on well known industry benchmarks. We also work on advanced multimodal data processing technologies using LLM, such as scalable and efficient semantic operators and AI functions.

Besides achieving great business impacts, we also encourage publishing on top tier conferences. In year 2025 alone, our team published nearly 20 papers in top tier conferences, such as SIGMOD, VLDB, FSE, ICLR, Euro Sys, WWW etc. We hire students with great technical skills, willingness to learn and solve complex technical challenges and passion in making an impact on millions of users.
