💡 Why it matters: Chatbots, translation tools and writing assistants all depend on software that works with human language. Language AI engineers build and improve those systems, and check that they are accurate and fair across languages.

⏰ A day in the life
Your translation tool works well for English but stumbles on a language with far less online text. You gather examples with native speakers, retrain the model and compare the results with careful human checks. You end the day writing up where it still fails so nobody trusts it too much.
