Questions

Can a foreigner apply for these roles?

47 of the 55 roles here state no citizenship or security-clearance demand. A role that does says so in its advert, and the card marks it.

Which companies hire most DevOps engineers?

Leidos (8), Amazon (6), Hitachi (3), GE Vernova (2), BAE Systems (2).

Which roles count as DevOps jobs?

Every role whose work is running and automating infrastructure - DevOps, CI/CD and release engineers, site reliability and observability, cloud (AWS, Azure, GCP), platform and Kubernetes, infrastructure and data center engineers, system and database administrators - at any employer. A role is filed under a specialty when its title names one; the rest are DevOps engineers.

How fresh is this?

Every role is re-checked on the employer's own careers board at least every 48 hours, and the page is rebuilt every night.
