We are a small team of engineers (5 today, and growing) where every employee has full ownership of the projects they work on. You'll join a high quality team of experts from various prestigious academia and companies, with a strong opportunity to grow your skills. We apply industry best practices (for instance, code reviews).

Here are some of the things that our engineers have been working on in the past few weeks:

• Developing snappy, beautiful UIs.
• Writing big data pipelines that crawl, process, and index terabytes of data.
• Improving the efficiency of machine learning algorithms to classify images and detect spam.

We're lean and focused: we move fast and release several times a day. Other than our weekly sprint meeting you won't find much politics here.

We enjoy our offices located in the heart of Paris's historic district. We will also consider remote applications for outstanding candidates.
