Responsibilities
Our team is at the forefront of building and optimizing content safety systems. With a focus on optimising and advancing content safety, we leverage advanced large language and multimodal models to enhance review efficiency, risk control, and user trust. Working closely with business and technical stakeholders, we deliver scalable solutions that keep pace with rapid global growth. - Own case-level analysis and governance for high-risk content, over-enforcement (false positives), and under-enforcement (false negatives) in the TikTok LIVE ecosystem - Conduct deep Root Cause Analysis (RCA) based on real cases to investigate metric fluctuations (e.g., CGVR, COR, reports) - Abstract common risk patterns from individual or small sets of cases, and assess whether issues are isolated incidents or systemic problems - Work closely with Product, Algorithm, Data, and Moderation teams to translate analysis findings into strategy, model, or process improvements.

Preferred Qualifications - Experience with model or strategy evaluation, including A/B testing and performance analysis in safety or risk-related contexts. - Working knowledge of model evaluation metrics (e.g., Precision, Recall, F1) and the ability to apply sound judgment when interpreting metric changes. - Understanding of human–machine collaboration, including trade-offs between automated models, human review, and policy or strategy decisions. - Experience with multilingual content, international products, or cross-market operations, with sensitivity to cultural and regional risk differences.
