About the role

Our clients operate in 14 countries. Their customers write support tickets in Portuguese, Thai, German, Vietnamese, and eight other languages — often mixed. Our current NLP system handles English well and falls apart everywhere else. We need an NLP engineer who has actually shipped multilingual classification and entity extraction at scale — not someone who knows the theory, but someone who has fixed models when they failed across language pairs.

Responsibilities

  • Build and fine-tune multilingual classification and extraction models
  • Design language detection and routing pipelines
  • Evaluate model performance per language and identify gaps
  • Collaborate with annotation teams on training data quality
  • Document model behaviour and limitations for client teams

Requirements

  • Strong experience with multilingual NLP (cross-lingual models, mBERT, XLM-R)
  • Python and Hugging Face Transformers
  • Experience with text classification, NER, or intent detection at scale
  • Familiarity with translation pipelines and language detection
  • Able to evaluate model performance across language pairs

Benefits

  • Interesting multilingual NLP challenge
  • Full remote
  • Competitive salary
  • Conference budget
  • Small, expert team
