AI Agent Algorithm Engineer Graduate (Global E-Commerce, Conversational AI) - 2027 Start (PhD)

We build the next-generation unified Agent system for TikTok's global e-commerce customer service — running in 30+ languages across one of the largest e-commerce surfaces on the internet. Our north star is a self-evolving Agent, where post-training, harness, memory / context engineering, tools, and evaluation form one closed loop, and every served conversation becomes the next iteration's training / eval / retrieval / skill-induction signal. We build the agent runtime itself — Codex / Claude-Code-class — not prompts on top of a vendor API. As a new grad, you'll own a real end-to-end piece from day one and ship it to production.
