DeepL...

is Germany's best-known AI company. We develop neural networks to help people work with language. With DeepL Translator, we have created the world's best machine translation system and made it available to everyone free of charge. Over the next few years, we aim to make DeepL the world's leading language technology company.

Our goal is to overcome language barriers and bring cultures closer together.


What distinguishes us from other companies?

DeepL (formerly Linguee) was founded by developers and researchers. We focus on the development of new, exciting products, which is why we spend a lot of time actively researching the latest trends and technologies. We understand the challenges of developing new products and try to meet them with an agile and dynamic way of working. Our open and positive workplace philosophy enables employees to feel comfortable and thrive in their roles. In our daily work we use modern technologies - not only to translate texts, but also to create the world's best dictionaries, and solve other language-related problems.

When we tell people about DeepL as an employer, reactions are overwhelmingly positive. Maybe it's because they have enjoyed our services, or maybe they just want to get on board with our quest to break down language barriers and facilitate communication.



What will you be doing at DeepL?

Thanks to our unique neural networks, DeepL is able to deliver the world’s best translation quality. In order to keep it that way, we are constantly improving our apps and adding exciting new features - and this is where your experience in developing sophisticated software comes in. 

You will be developing C# backend services (running on .NET Core on Linux) for products that help millions of people in their everyday lives. You will be part of a highly motivated team that values easy to maintain and efficient code. Important design decisions are made by the whole team in open discussions.
