Cohere is hiring a senior technical staff member to build the web-data pipeline behind its pretrained language models. The work covers extraction, parsing, deduplication and filtering of large web corpora, quality scoring, and analysis of how data composition and mixtures affect model performance, alongside research and evaluation teams. The posting asks for strong software engineering, Python, data-processing frameworks such as Spark, Beam or Pandas, and experience with large-scale web datasets. Distinctive: the role is fully remote with no location restrictions, though EST or EU hours are expected.
