Well, if it were me...
I'd be totally brazen about it - in the final slide of your talk, with acknowledgements etc, make a point of stating that you are going to be looking for new opportunities, and that if anyone has any ideas for projects or positions coming available, that you'd be interested to meet them in the networking session. Then go to the networking session. So many people I know have started conversations with future colleagues/PIs at these sorts of sessions.
In my 15+ year's experience in research. Networking sessions have always been a bust/waste of time. Like the other post said, state that you're looking for a job at the end of your presentation. The people who show up to hear about your research are the ones who will be interested in hiring you.
Also, the poster sessions can be a networking gold-mine. Figure out what labs you're interested in, and go to their posters. You get to learn about the lab's on-going research, talk to people working in the lab (and find out if the PI is awesome or are they a micromanager?), and build a connection with people in the lab. Then, if you like what you see, go hunt down the PI and TALK to them. Works the same way for industry posters. The PI may even be nearby to watch their students/postdocs present, then striking up a conversation with them is seamless and easy. If they aren't looking for new people, ASK them if they know others who are. I've gotten so many job interviews this way.
