Worldwide: [Which companies use Unix?](https://jobspipe.dev/technologies/unix)

## FAQ

### How many companies use Unix in United States?

4,688 companies in United States have job postings that show they use Unix, as of 25 Sep 2026. 765 are confirmed and 3,923 are likely.

### Which companies use Unix in United States?

Amazon Web Services (AWS), Infosys, NTT DATA, CGI, Lockheed Martin are among the confirmed Unix users with the most postings naming it in United States. The full list on this page names 100 companies.

### How does JobsPipe know a company uses Unix?

From the company's own job postings. Each posting is read for the technologies it names, and every company and technology pair is graded: confirmed when two independent checks agree on Unix in at least one posting, likely when it is a stated requirement or appears in two separate postings. A single passing mention is not counted here. It is evidence of a team working with Unix, not a purchase record.
