Beyond our technological prowess, we take pride in fostering a collaborative and innovative work environment, making RetailSonar not just a leader in the industry but also a great place to work. In line with our ambitious expansion plans, we are actively seeking a talented Senior Machine Learning Engineer to join our dynamic team in Ghent.

In this position you will be working on our core technology and bringing this to the next level.

As a Senior Machine Learning Engineer, you will take on following main responsibilities:

  • Develop innovative machine learning algorithms in the field of customer behavior analysis from a variety of data sources.
  • Bring these algorithms to production, and take care of quality monitoring

  • Are not afraid of diving into legacy code, and port it to today's standards.
  • Commit to work, and get the job done.

  • You are fluent in English (Dutch is a strong plus) and are not afraid to talk to different stakeholders within or outside the company. You can easily adjust your communication style and translate technical jargon into understandable pieces of information.
