Great Idea. I ran a page on an old site of mine: "Hot Startup Jobs" and regularly posted the job vacancies from recently funded startups in Israel. It was a very popular page, but doing everything manually: tracking what's being funded, copying and pasting the jobs, the companies not cooperating/adding and the users not giving anything back -- it was too draining.
Tips: have an RSS feed on search results. For companies, show date of last funding round, preferably with a link to its funding announcement and its jobs page.
But then again, most of the companies that come up for Boston are not actually in Boston. Need something like address:Boston, but they don't seem to have implemented that yet.
