ByteDance's Governance & Experience Algorithm Team is looking to solve complex challenges in e-commerce by building a trusted and efficient ecosystem. This involves tackling issues like false advertising, low-quality products, and optimizing logistics performance to improve the overall user experience and seller compliance.
Requirements
- Proficient in Python/C++ and machine learning frameworks (PyTorch/TensorFlow)
- Deep experience with graph neural networks, time series analysis, or LLM
- Track record of delivering AI solutions with measurable business impact
- Experience in anti-fraud, prediction/forecasting, e-commerce governance, or related fields
Responsibilities
- Build graph-powered risk networks to uncover similar product clusters and high-risk seller/creator groups in emerging markets, reducing false advertising incidents in global regions.
- Develop LLM-based multi-modal systems using cross-modal fusion (text, images, behavioral data) to detect false advertising and low-quality products.
- Deploy AI-powered product business suggestions to improve seller compliance and user trust.
- Lead time-series forecasting innovation for logistics performance metrics (e.g., delivery delays, cancellation rates), driving improvement in the e-commerce experience through predictive analytics.
- Develop multi-task models using MMoE and dynamic loss functions, driving measurable improvements in platform product, service, and logistics health.
- Optimize LLM reasoning with DPO/GRPO to enhance fraud detection, outperforming traditional SFT methods.
- Construct heterogeneous graphs modeling product - seller - creator - video - user relationships, enabling improvements in product lifecycle insights and detection of similar product patterns.
