About the Role

You will develop and optimize Reinforcement Learning (RL) models for enterprise-scale applications such as customer service, token reporting, compliance, and Web3 domain reasoning.

You will explore and evaluate advanced Algorithms including PPO, GRPO, DPO, RLHF, RLAIF, and Agentic RL to enhance the capabilities of LLMs, VLMs, and Agentic AI at Binance. The role requires a strong theoretical foundation in RL—covering policy optimization, reward modeling, and planning—paired with the Engineering skills to build scalable production systems.

You will take full ownership from research through deployment, driving experimentation with systematic evaluation and benchmarking. Collaboration across research, infrastructure, and application teams will be key to delivering impactful AI solutions.

Responsibilities

• Research and develop state-of-the-art RL algorithms, focusing on large model optimization and alignment techniques.
• Design and implement RL training pipelines, including environment simulation, data generation, and reward function design.
• Apply Reinforcement Learning methods to enhance LLM / VLM / Agentic AI capabilities in reasoning, planning, and autonomous decision‑making.
• Collaborate with Engineers and researchers to integrate RL solutions into enterprise AI platforms.
• Monitor model performance in production and continuously improve through iterative training and fine‑tuning.
