Make a list of papers that you find interesting and find out where they are published. Chances are, the venues that publish things you find interesting publish other work you'll like too.
For instance: USENIX ATC, USENIX Security, OSDI, SOSP, PLDI, ICSE, FSE, NDSS, ASPLOS, and CCS consistently have work I find interesting.
