Omar KhanOmar Khan, the Samsung exec who often introduced the world to Samsung’s latest Galaxy phones and tablets at events, has been hired to lead mobile initiatives for Citigroup.

“Omar Khan was a valued member of the Samsung Mobile US team but has decided to leave Samsung Mobile to pursue another opportunity,” Samsung said in a statement. “Omar is not leaving to join a competitor to Samsung, and we anticipate having a continued relationship with him once he settles into his new role.”

Khan left his VP position at Motorola in 2008 to join the Samsung Mobile team as Senior VP of strategy. Many of Khan’s duties will shift Tim Rowden, VP for product development at Samsung Mobile.

Khan isn’t the first mobile executive to leave for a financial services company, as Dan Schulman, who used to head Virgin Mobile, joined American Express to lead its mobile business operations.

Citi indicated in a press release that it was excited to create the new position for Khan in order to help the company deliver its products and services to new mobile devices that are shaping world commerce.
