Benoit Dupin, Vice President of Amazon A9′s Search Technology group, has left the high-profile search technology firm to take up a job with Apple. Dupin’s profile from Amazon A9′s executive management website disappeared this week, and his LinkedIn profile has been updated to reflect that he began his position as a director at Apple this month. Amazon A9 is Amazon’s Palo Alto, California-based subsidiary that focuses on developing Amazon’s marquee search and advertising functionality.
