– Strong technical skills, good system and infrastructure understanding.
– Good organizational skills
– Ability to teach and convey concepts in data science to researchers in other disciplines

2) Chief Data Scientist – long-term (>= 5 years) position

– Support and advance data science research at the university of Haifa
– Promote activities to engage researchers in collaborative research in data science
– Advise researchers on their data science projects
– Supervise the data science service unit
– Help with planning and overseeing the education plans of the center
