About our Team We are the supply chain and logistics algorithm team under Global E-commerce. We focus on technical optimization of the global logistics and fulfillment process. Through the in-depth integration and innovation of cutting-edge AI algorithms such as reinforcement learning and large models, combined with operations research optimization technologies, we drive logistics cost reduction, service efficiency improvement, and user experience enhancement. Our team is currently expanding rapidly with locations in Hangzhou, Shanghai, Singapore, and Seattle. We focus on the algorithm implementation and breakthroughs of the self-owned logistics system, deeply participate in the full-link intelligent optimization projects from warehouse distribution to last-mile delivery, and focus on tackling the implementation of core directions such as reinforcement learning in dynamic and real-time logistics scenario decision-making, and large models in complex supply chain deduction and intelligent interaction. We continue to empower the global e-commerce logistics business with cutting-edge algorithms. Job Responsibilities 1. Responsible for the implementation of operations research and AI projects related to self-owned warehouses and quasi-self-owned warehouses, promote the algorithm research and development of in-depth cooperative innovation warehouses with service providers. Apply deep reinforcement learning to core in-warehouse links such as intelligent order batching, wave picking, and dynamic packaging optimization, complete the implementation and iteration of internal systems, and break through the efficiency bottleneck of traditional operations research optimization in complex dynamic scenarios. 2. Take charge of the algorithm construction for First-Mile/Last-Mile scenarios. Based on the reinforcement learning framework, make decisions on dynamic collection route planning, intelligent merchant onboard/offboard, and real-time regional division. Iterate the platform's intelligent order allocation algorithm and the GTL three-segment code prediction model at the delivery station level. Implement a LLM-driven intelligent labor scheduling optimization plan, which automatically generates scheduling strategies combining business rules and real-time capacity fluctuations to improve the efficiency of last-mile fulfillment. 3. Participate in global logistics backbone network planning projects, build the ability to simulate complex supply chain scenarios based on large language models, accurately assess the changes in timeliness, traffic and platform profits corresponding to changes in warehousing and distribution, deepen the implementation of large models in multi-scenario simulation and automatic parameter optimization in network planning scenarios, and optimize the decision-making efficiency and scientific nature of global logistics network layout. 4. Responsible for the research and development of intelligent scheduling algorithms in Middle-Mile scenarios. Lead the algorithm design and implementation of cross-regional logistics projects such as the US TPE(Transportation Planning and Execution) project. Apply reinforcement learning to dynamic route planning and capacity scheduling for trunk line transportation, and continuously optimize the cost and timeliness stability of trunk transportation. 5. Explore the implementation of AI
