Harmattan AI is a French defence technology company founded in 2024 that develops autonomous strike and reconnaissance drones for European armed forces. Its systems are designed around the lessons of the war in Ukraine: low cost, produced at volume, and able to complete a mission when satellite navigation and radio links are jammed, which is now the normal condition on a contested battlefield. Headquartered in Paris and backed by European defence investors, it is part of a wave of new European companies formed to reduce the continent's dependence on American and Israeli defence suppliers.

Questions

Can a foreigner apply for these roles?

139 of the 215 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 (147), Naval Group (22), MBDA France (18), ArianeGroup (10), Harmattan AI (7).

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.
