The IBM User Experience team is looking for data scientists who work on data modeling and visualizing big data to participate in a usability test. Participants will be part of a structured interview with the IBM usability team, and provide feedback on a big data product's user interface. Participants should also be familiar with programs such as Cognos, SPSS, SAS, R, Matlab, Weka, Mahout or similar. The sessions will be held August 13-17, and will be approximately 2-3 hours in length. Pay is $75/hour for non-IBMers located in the United States or Canada. Participation will be done remotely through webconference and teleconference, and we can work to accommodate your schedule. For further consideration in the session, reply to this posting, and a questionnaire will be sent to you to complete.
