Questions

Can a foreigner apply for these roles?

21 of the 62 roles here state no citizenship or security-check demand. A role that does - a citizenship, a national security vetting, a US clearance - says so in its advert, and the card marks it.

Which companies hire most?

Thales Group (43), Naval Group (11), Airbus (6), Unseenlabs (1), MBDA France (1).

Which employers count as defence companies?

Companies whose main business is defence and security - prime contractors, defence electronics, naval, land and air systems, defence software and the defence tech startups - and the defence divisions of diversified groups. Companies of Russia, Belarus, China, Hong Kong, Iran and North Korea and companies under sanctions are left out.

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.
