Data & AI Jobs at LMArena

LMArena operates an AI ranking and leaderboard platform where users can chat with, compare, and vote on AI models, including large language models, image, and code models, to help shape a public leaderboard through real-world evaluation.

The data is messy and there is not much of it yet. You build the pipeline, train the model, then explain the result to a founder in plain words. Large employers give you a clean warehouse and one narrow question, while here you pick the question too.
