I doubt open source is a requirement at any of these companies, but it's a huge asset for any job application if you have some good work to show. It stands to reason that if you're going to be spending most of your day writing to code and interacting with coders, people will be interested to see if you have a good repo and handle issues well. So a good Github repo is a huge asset to any job seeker in this industry. It will also help you to be approached by quality companies if your project's popular/high-profile, as savvy recruiters will look at this kind of thing. And, you're likely to be asked about open source in your interview. So if you can say intelligent things about it and show you care about it, it might improve your interview performance too.
