My Background with Remote Work
From 2011-2015, I worked partially remote in a full-time position when working outside of the office was uncommon especially in NYC. In 2015, I left that company & began working fully remote. Even now, a remote position in the field in which I work (product management) is rare. Rarer still is a remote position as a Vice President of Product Management. But I was able to find these roles because I was dedicated to the job hunt. You too can find a remote position working from home or while living in other countries. It just takes effort and time.
1. The number of resumes submitted for a single remote position grow exponentially so you want your resume to be on the top of the pile. Act as if the job hunt itself is a part-time or full-time position. If you're already working, perform your remote job search for a couple of hours every day. If you're unemployed, spend at least 8 hours a day reviewing both remote & onsite positions. Remember, you can always negotiate working remotely part-time as well!
2. Search on a wide variety of solid, job search sites dedicated to remote positions. It can get annoying with duplicates appearing across sites, but skipping sites means you may potentially miss the one job post that's perfect for you. Here are the sites that I (& others) have used successfully. (And yes, we searched using all of the sites below simultaneously, not just a few sites.)
FlexJobs (Use this link to sign up, you can get up to 30% off)
Hired (You have to apply to get onto the site. It's free, but not all people get in. It depends upon your resume & your chosen field.)
