Social games firm SGN has already made a splash on iPhone, generating more than nine million downloads across its stable of titles.

Now it's signified its intention to push further into iPhone and mobile by hiring Eric Huynh as its new chief technology officer and VP of engineering.

Huynh was previously CTO of Worldwide Studios at Vivendi Games Mobile, and before that founding CTO at Gameloft, so his mobile credentials seem impressive. Before that, he was global CTO at Ubisoft.

He'll be overseeing product development and games research across mobile and social networking platforms for SGN, while also taking charge of technical standards, QA and delivery protocols.

“Eric brings over 15 years of world class expertise in gaming product development, creation and research,” says Shervin Pishevar, CEO of SGN (pictured).

“His proven track record in implementation, driving R&D and establishing top quality studios around the globe will make him an important asset as we continue to grow our company and suite of games."

It's a sign that SGN sees iPhone (and other mobile platforms, presumably) as crucial to its growth in the coming months and years.
