OpenAI's Data Understanding team builds pretraining datasets; it is hiring a research engineer or research scientist in Zurich, hybrid and full-time. The role treats data curation as research: developing methods to select, combine and transform data, synthesizing data, building VQ representations, and handling filtering, deduplication, quality control and tokenization, then designing experiments on how data choices affect model learning and turning results into scalable pipelines. The posting asks for a track record of new ML ideas and ownership of a research agenda. Distinctive: pretraining data treated as frontier research.
