9. CACI International
“Ever vigilant” is the motto of the number 9 in our list of biggest private security companies that are hiring, and it is quite fitting.
Their primary services are described on their website as providing “information solutions and services in support of national security missions and government transformation for Intelligence, Defense, and Federal Civilian customers.”
Some of CACI’s missions, in clear language, are working with the US government on secret missions. Not James Bond style, though, rather the messy and can-get-you-killed stuff which isn’t very glamorous. They also work on cyber-security, which is one the most forward threat at the moment. They have, according to their website, 20,000 employees in 120 locations worldwide and you can apply on their dedicated career’s website.
