Machine Learning Research Scientist

We use state-of-the-art AI plus intuitive UI to eliminate useless paperwork and make the whole world go faster. Help us build amazing machine learning models that scale to terabyte-sized datasets, tens of thousands of simultaneous users, and reliably serve the biggest enterprises and software vendors in the world.

We are already processing up to hundreds of documents per minute. But this volume grows exponentially and the scope of our product is only slightly slower. Our final goal is so far ahead that we won’t hesitate to re-design everything a couple of times more.

As a Research Scientist in Rossum AI Labs, you form the future of deep learning for document understanding and push the envelope in related computer vision and machine learning areas.

Rossum (the name comes from Czech writer Karel Čapek’s play “Rossum’s Universal Robots”) is capable of extracting data (from documents) six times faster than the human rate. Last year alone it managed to save companies across a number of sectors over one billion keystrokes, the equivalent of 150 years of human labor. Today, the company automates document communication for customers on five continents and a client roster that includes Siemens, Bosch, Cushman & Wakefield, Veolia, and, here in the Czech Republic, Alza, Kofola, and Mattoni.

After tripling our revenue in 2020 and securing Eastern Europe’s largest-ever Series A funding of $100M in 2021, we plan to further expand our market share and invest heavily across our Go-to-market teams & our research and development backbone.

Our product is number #1 in its category.
