Is LinkedIn starting to feel more heat from Facebook? The San Francisco-based company is looking for an on-site Developer Network Manager to act as an intermediary between the company and API developers. The ad (registration required) says they're looking for someone with a combination of marketing, technical, and communication skills and also outlines pretty clearly that the job entails a lot of API program evangelism. They even go so far as to say that whomever they hire should be prepared to build a "LinkedIn Developer Network from the ground up.

Could this be further indication that LinkedIn realizes it needs to take a hard look at what Facebook is offering and at least make a run at matching what they have to offer if they want to stay competitive in the social network market?
