Tallinn is the centre of Estonia's defence tech sector, with nearly all of the country's tracked positions based in the capital. The NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE) is headquartered here, and Estonia's advanced digital governance infrastructure has helped attract cybersecurity, robotics, energy and air defence startups. For a country of 1.3 million people, the concentration of defence technology companies in a single city makes Tallinn an unusually dense hiring market where candidates can move between employers without relocating.
