Turn research ideas into production systems.
Help establish engineering practices and hire future team members.
What We're Looking For
At least 2 years of hands-on experience in reinforcement learning or machine learning engineering.
Strong Python skills and deep experience with PyTorch or JAX.
Practical experience training models with reinforcement learning methods, including policy gradients, reward modeling, or RLHF.
Experience with distributed training, GPU infrastructure, RL environments, reward functions, training pipelines, and model or agent evaluation.
A track record of taking research ideas into production systems.
A degree in computer science, mathematics, physics, or a related field; a master's or PhD is a plus.
LLM post-training or agent training experience is beneficial, as are RL publications or open-source work and experience with simulation frameworks or training libraries.
