职位介绍
You will lead the research and engineering of multimodal agent systems, focusing on planning, tool use, memory, and retrieval to solve real design, vision, and language tasks.
Scale post-training and reinforcement learning across distributed PyTorch pipelines, ensuring efficient, reproducible training of large models and MoE architectures.
Design and implement reward models and learning loops (RLHF/RLAIF, preference modeling, DPO/IPO-style objectives, offline/online RL, curriculum learning) for multi-step reasoning.
Create simulation environments and evaluation suites to surface failure modes (planning errors, tool use brittleness, hallucination, unsafe actions) and turn them into measurable targets.
Lead rigorous evaluation: offline suites, online experiments, and data-backed conclusions; collaborate with product, safety, and platform teams to ship reliable features.
Mentor teammates, present results, and contribute to the research community while upholding high standards of reproducibility and safety.
