HTC, a Taiwanese mobile phone manufacturer that has a headquarters office in Bellevue, announced today that Jason Mackenzie has been promoted to vice president of sales and marketing of HTC America.

HTC works closely with Microsoft to build Windows Mobile-based phones and devices, and with Cingular (now AT&T) and T-Mobile, which also have major operations here.

Mackenzie is replacing Todd Achilles, who left HTC about a month ago for personal reasons.

As I wrote in this blog post, Achilles said he's enjoying some free time, having traveled about 80 percent of the time for work.

Mackenzie seems to be a fitting replacement, having started working at HTC in 2005 as one of the founding members of the HTC America leadership team, and helped grow the Bellevue office to more than 100 employees in two years.

"As one of our first employees in the Americas, Jason has a strong track record of working with partners, leading teams and developing sales channels," said HTC Chief Executive Peter Chou.
