Virtual job positions continue to increase in popularity.

If you value becoming a remote worker or staying one, you can find countless companies hiring to fill work-from-home positions.

With so many people seeking remote work, beware of work-from-home sites that promote fake job ads and other scams. Below is a list of nine reputable work-from-home job sites that offer a wide range of legitimate remote jobs.

1. FlexJobs

Launched in 2007, FlexJobs was created specifically to help professionals find remote and flexible jobs. The site’s founder, Sara Sutton, explains she was inspired to start FlexJobs because she had been looking for a remote opportunity with a flexible schedule while pregnant and was discouraged by how many bogus job sites there were in this niche.

FlexJobs’ staff researches what they identify as the best job listings for professional positions in more than 50 career fields worldwide. Opportunities are part-time, full-time, on a flexible schedule and on an alternative schedule. Positions range from entry-level to executive-level. FlexJobs provides client support for members and a money-back guarantee. Pricing starts at $2.95 for a 14-day trial.

2. Remote.co

Remote.co, a FlexJobs partner also founded by Sutton, describes itself as a site for “all things remote work.” It offers sections for employers to post remote jobs and for job seekers to find those opportunities. The site also includes a remote work blog and common work-from-home questions answered by 146 remote companies and virtual teams.

3. Indeed.com

One of the major job search sites for traditional work, Indeed also has a special section for remote jobs. The site currently lists more than 47,000 remote jobs that are searchable by job type, keywords or company. Indeed also lets users browse companies by industry, search for salaries and upload resumes so that employers can find them.

4. We Work Remotely

According to the We Work Remotely site, its community has over 4.5 million visitors. The site lists remote jobs in categories including programming, design, customer support, and sales and marketing. It also designates between full-time and contract positions. We Work Remotely also offers a number of resources for remote job seekers including a Remote Leader Playbook, remote work trends and the top 100 remote companies.
