Member of Technical Staff

Job description

Job responsibilities

• Design and build RL environments, evaluations, and datasets that target high-value gaps in frontier model capability
• Develop internal platforms and supporting infrastructure to run hundreds of thousands of tasks at scale, with the throughput, reproducibility, and observability that demands
• Collaborate directly with researchers and engineers at leading AI labs to scope and shape dataset development against their model roadmaps
• Make quality measurable — build the grading harnesses, metrics, and automated checks that tell us whether an environment or dataset is actually good
• Prototype fast, then harden what works into production systems others can run without you
• Contribute back to our open source projects where it accelerates the broader community

Job requirements

• Practical experience with agents, evaluations, or RL workflows.
• Strong technical background and written communication
• Nice to have: experience with computer vision or multimodal models, or prior work with an AI lab as a data or evaluation partner
