Since earlier today you can now do a proper geospatial search for jobs:
http://jobs.perl.org/search?location=los+angeles
Not all of the current postings on the site have been geo coded, but they should expire over the next couple of weeks anyway. :-) All new postings are required to be geocoded if they have a location.
(If you are an employer posting, just editing the job will get your listing geocoded, too).
