TikTok is the leading destination for short-form mobile video, and our mission is to inspire creativity and bring joy. The E-commerce Global Supply Chain and Logistics team is dedicated to enhancing clients' shopping experience and reducing logistics operational costs in TikTok E-commerce. We are currently seeking a Senior Machine Learning Engineer who possesses a deep understanding of machine learning (ML), operations research (OR), data mining, and statistical inference. This position can be fulfilled in our San Jose and Seattle offices. In this role, you will be responsible for building deep learning and statistical models to provide end-to-end estimated time of arrival (ETA) predictions for e-commerce logistics. You will fine-tune ETA expressions to improve the click-to-order rate while balancing negative review indicators. Additionally, you will utilize data mining tools to construct logistics network knowledge graphs, which will enable the development of a situational awareness and early warning system for logistics fulfillment. This system will help operations discover and address logistics network anomalies, thereby improving fulfillment quality in collaboration with logistics service providers. You will analyze and predict the spatio-temporal trajectory sequences of express packages using deep learning, statistical inference, and other algorithmic methods. This trajectory prediction will enhance our understanding of logistics network dynamics, improve ETA prediction accuracy, and provide essential sample features for other prediction tasks. Furthermore, you will build a service network design (SND) model for selecting locations for transshipment centers and last-mile stations based on anticipated increases in logistics order volume. Your role will also involve extracting directions for logistics operation optimization, cost reduction, and service quality improvement through a comprehensive understanding of supply chain and logistics scenarios. Finally, you will develop innovative and state-of-the-art e-commerce logistics models and algorithms.
