NEW YORK ( TheStreet) -- Twitter has posted a job opening for a financial reporting manager, to help when it goes public. That could be sooner than you think. According to a job posting on LinkedIn (since taken down), the company is looking for someone to help it prepare monthly reports, quarterly and annual financial statements, as well as the S-1 filing, when the company is ready to go public. Twitter could not be immediately reached for comment for this story. In late 2012, I predicted that Twitter would file its documents to go public in 2013, but would actually go public sometime in early 2014. Given the timing of the job posting, it appears that this timeline is still on par. In recent months, Twitter executives, most notably CEO Dick Costolo, have pushed aside the notion that the company is going public soon. At the D11 conference in May, Costolo said it's not an issue "I spend a lot of time thinking about." When Costolo made those comments, everyone in the technology field, myself included, said that was far from believable, given the hype surrounding Twitter. The San Francisco-based social network is reported to have a valuation of close to $10 billion on private markets, and could generate as much as $1 billion in advertising revenue in 2014, according to eMarketer. Despite not being a public company, Twitter seemed to back up those numbers. In mid-2012, Twitter said it "expects to generate at least $1 billion in sales in 2014." By 2015, eMarketer believes that Twitter will generate $1.33 billion in ad revenue, with more than 60% of that coming from mobile. Given the hoopla surrounding Facebook's ( FB) IPO, it will be interesting to see whether Twitter commands as much attention as Facebook did. -- Written by Chris Ciaccia in New York >Contact by Email.
