Senior IT Systems Engineer, Network at Thumbtack
San Francisco, CA, US

Have you ever tried to hire a plumber? How about a house cleaner? If you have, chances are it took you way longer than it should. In the era of instant-everything, it’s crazy that you still have to waste an entire afternoon researching, calling and vetting local service professionals whenever you need one.
