I had a look over at Stack Exchange https://stackoverflow.com/jobs/cv/create. I am not sure if it would be possible to do the same with Earth Science Stack Exchange. I mean post doctoral opportunities, jobs, etc. Perhaps not but no harm asking the question is there(by the way I am not looking for a job so no personal interest in this )

The long-term plan for Stack Overflow Careers/Jobs has been to expand it across the network. From Please don’t make Careers developers‑only in practice!:
FWIW, I don't know what the long-term plans are for other sites, but I certainly hope we wouldn't deny jobs for professionals who are active on Stack Exchange just for the sake of a different URL scheme; this is all about serving MORE people, not fewer! Once upon a time, the dream was that every site would have an associated section for jobs, a place where everyone from chefs to physicists could turn their knowledge into a live portfolio... We're still a long, long way away from that, but I'd like to believe that better integration with Stack Overflow is the first step along that road.
As Shog9 states there though, this is a long way from happening. Careers/Jobs right now could certainly have some applicable jobs; some folks on here are programmers too and might be able to find a job that integrates both programming and earth science. However, for the time being, Careers/Jobs is nearly all for programming jobs. Eventually this might change, but currently that's the best we can do.
