## Job description

We are building next-generation end-to-end autonomous driving systems powered by reinforcement learning.
You will work on applying RL in closed-loop, safety-critical environments , leveraging large-scale simulation and real-world driving data to improve safety, comfort, and robustness.
Train and deploy RL policies in closed-loop driving environments
Scale RL training using massively parallel simulation systems
Design and optimize reward functions for complex driving behaviors
Improve sim-to-real transfer for real-world robustness
Collaborate with cross-functional teams to integrate models into production systems
Requirements
Core Technical Skills
Proficiency in modern RL algorithms: DQN, PPO, SAC, TD3, etc.
Proficiency in modern RLHF algorithms: PPO, DPO, GRPO, etc.
Hands-on experience training reward models and finetuning LLM/VLM/VLA
Knowledge of distributed RL training at scale
Proficiency with massively parallel simulation environments
Knowledge of sim-to-real transfer techniques and domain randomization
Proficiency in Python, comfortable with C++
Proficiency in deep learning frameworks such as PyTorch
Experience with distributed training frameworks (Ray, Horovod, etc.)
Knowledge of model optimization (quantization, pruning) and CUDA is a plus
Knowledge of traffic rules, driving behavior modeling
Preferred Qualifications
Publications in top-tier venues (ICML, NeurIPS, ICLR, CVPR, ICCV, ECCV, ICRA, IROS, etc.)
Open-source contributions to RL libraries or autonomous driving projects
Previous experience with LLM fine-tuning using RLHF
Knowledge of safe RL, interpretable AI, or robustness techniques
Familiarity with autonomous vehicle regulations and safety standards
