The best way to see qualifications for the different jobs available at Ubisoft is to go to the company website (www.ubisoft.com) and then choose 'Careers" from the drop down menu.
Here is the direct page for that: https://www.ubisoft.com/en-US/careers/experience.aspx
On that page, click on "Search for jobs" and you can then select all the different types of jobs that you are interested in to see what their requirements are.
