Research Engineer, Visual Knowledge Work

Job summary

Responsibilities

We're looking for a research engineer who believes that visual and spatial reasoning are core to fully unlocking the capabilities of LLMs. On the Vision team, you'll own the end-to-end process of creating training data and RL environments targeting visual knowledge work: identifying long-horizon…

• Own the data strategy for vision capabilities end-to-end, from building evals and scaling RL environments
• Manage technical relationships with external data vendors, including writing task specifications, evaluating visual data and annotation quality, and iterating on reward design
• Develop and improve QA frameworks that catch reward hacking and ensure environment quality at scale
• Run generalization experiments to measure how data strategy changes improve multimodal capabilities on held-out evaluations
• Partner with pretraining, RL, and product teams, and do the science that shows we’re all rowing in the same direction

What they're looking for

• Designing evals or benchmarks for LLMs or vision language models
• Large-scale pretraining, SL, and RL on language models
• Deep learning research on images, video, or other modalities
• Developing complex agentic systems using LLMs
• Large-scale ETL and data pipeline development
