Mobile ad network Millennial Media Tuesday announced a pair of new management hires: Matt Gillis as senior VP of business development, and Eric Hastings as senior VP of engineering, a newly created position overseeing the company's technology systems. Gillis has more than 15 years experience working in mobile software including at Japanese mobile game company Capcom, while Hastings joins Millennial from AOL's Advertising.com.

Millennial also plans to hire another two dozen engineering, operations and sales  employees in its Baltimore and San Francisco offices by year's end to keep pace with revenue and client growth. Staffing at Millennial is already up 34% over last year. The ad network was recently rumored to be an acquisition target of Research in Motion but the BlackBerry maker  reportedly balked at Millennial's asking price of $400 million to $500 million.
