Machine Learning Engineer

Your role will be to architect and develop solutions that automate machine learning processes – training, versioning, serving, deploying in production – as well as improving our data management stack that is written primarily in Go.


Since 2013, under the name of Fornax, we have been working in consulting in AI/Machine Learning/Big Data, appearing as machine learning experts or providing comprehensive end2end solutions. We have gathered a group of ambitious people, with experience in major technology companies, and our employees have been laureates of many international competitions, including victories in competitions on Kaggle.

We’ve done various projects in different industries, but one thing that has not changed is the desire to write a really decent code and the best innovative exploration of the subject, so that the quality of our work was our best advertisement. We do not want to follow the crowd but we strongly believe in changing the status quo.

The best illustration of these words is our product – ShelfWise. It is a world-class solution based on deep learning and image recognition, allowing for instant analysis of the store shelf. We debuted with ShelfWise in Singapore, delivering it to one of the largest FMCG companies in the world. Currently, we carry out tests and pilots with the largest companies in the country, and we are just starting to spin!


You will become a member of a team that is not afraid of ambitious and great challenges. We are shaping ShelfWise so that it is an extremely useful and practical tool. If you want to have a huge impact on an innovative and cutting-edge product and become part of the exciting digitization of one of the most traditional sectors of the economy, we can not do anything else but encourage you to talk to us.
