RL Engineer

About the Role Join a small, early-stage team building training data and evaluation infrastructure for advanced AI models. You will design reinforcement learning environments, datasets, and evaluation methods that help models improve across complex, real-world tasks. What You'll Do Design data slices and agent tasks that reveal meaningful model failure modes across areas such as finance, coding, and enterprise workflows. Build and refine evaluation rubrics and reward signals for RLHF and RLVR t…
