206 jobs for "Performance Engineer"

Responsibilities

The TikTok AI Data Service and Operations (ADSO) team advances AI across TikTok by turning human expertise and real-world insight into data for model training, evaluation, and improvement. We work with product and algorithm teams to develop data standards, build evaluation datasets, and identify opportunities to strengthen model performance.

Human judgment is nuanced and context-dependent, while models and product requirements continue to evolve. We translate that judgment into consistent data across languages, domains, and product scenarios, combining domain expertise, AI-powered automation, and global operations to improve evaluation methods and data production systems.

You will collaborate with algorithm, product, engineering, and operations teams throughout the model development lifecycle. This provides opportunities to deepen your understanding of AI systems, shape how models are trained and evaluated, and see how stronger data and evaluation practices inform product improvements.
