What else distinguishes us from other companies? 

DeepL (formerly Linguee) was founded by developers and researchers. We use the latest techniques in machine learning, neural networks, and natural language processing (NLP) not only to translate texts, but also to create the world’s best dictionaries and solve other language problems. We are still planning a lot of exciting features for our services, so we are looking for exceptional developers who want to learn a lot and enjoy teaching the computer unique things. When we talk about DeepL or Linguee as an employer, a lot of people react very positively. This is because they are often pleased with the free, open service.
