About the job
Team Introduction We’re the core team building LLM-powered agentic systems that drive and accelerate seller growth across global markets. We bring cutting-edge AI into production at scale — from applied LLMs and multi-agent systems to real-world business impact in one of the fastest-growing e-commerce ecosystems in the world.
We’re looking for brilliant and motivated ML engineers eager to apply their knowledge in machine learning (ML), operations research (OR), data mining, and large-scale intelligent systems to real-world challenges. If you love building, experimenting, and shaping how AI transforms commerce, we want to talk to you. Applications are reviewed on a rolling basis — we encourage you to apply early.
Responsibilities
- Develop and deploy deep learning and LLM-powered systems for merchant operational tools and global e-commerce growth scenarios.
- Leverage large-scale e-commerce data to power agentic systems that generate actionable insights — from CRM content generation and store decoration to automated email reply and outreach optimization.
- Use ML models to predict seller performance, identify growth gaps, and provide agent-based recommendations (e.g., campaign design, pricing, and promotions).
