Cohere is hiring a machine learning engineer for pre-training data. The person will build the pipelines behind Cohere's language models, run data ablations to assess quality, and design data mixtures and curation methods that improve training throughput. The posting asks for strong Python and data-pipeline skills, experience with Spark, Beam or Pandas, large-scale web, code and multilingual corpora, and familiarity with curriculum learning, data mixing and data attribution. The role is remote within EST-to-EU time zones with no in-office minimum; a top-tier publication record is a bonus.
