Removing the BlueJeans from your machine is a little more involved because they actually used launchd.

launchctl list

Then you need to find where the plist files are (i.e. com.bluejeans.app.detector.plist).

You can disable an entry from launchctl list:

launchctl disable uid/<your user uid>/com.bluejeans.app.detector

You can also unload if you find the actual file

launchctl unload ~/Library/LaunchAgents/com.bluejeans.app.detector.plist

There were a couple differently named bluejeans agents.
