  • Excellent skills in Java
  • Well-versed in SQL, basic mathematics and statistics
  • Working knowledge of the Hadoop ecosystem, preferably Spark
  • Experience in working with UNIX
  • Familiarity with Maven and Git is a strong plus
  • Very good communication skills, fluent in English
  • Having one or more of the following is not required but nice to have
