Cursor is hiring a mid-level software engineer for its RL Environments team, on-site in San Francisco. The work spans platforms for building realistic reinforcement-learning environments at scale, pipelines that turn large raw datasets into training-ready environments, shared quality standards across vendor, tutor, acquired and synthetic data, and self-serve APIs and tooling for contributors.
