What we’re looking for

  

As a senior data scientist, you will be responsible for developing high-quality, scalable, and well documented R scripts, and keeping up to date on the latest research in the field of automatic machine learning and artificial intelligence as well as best coding practices to help guide the development of Argus methodology, our algorithms & dashboard. Our algorithms involve programming in R & SQL. We are looking for a person with strong problem-solving skills, that not only knows how to code, but what to code, and who is able to discuss the best way of implementing a given methodology.
