Questions

Can a foreigner apply for these roles?

354 of the 354 roles here state no citizenship or security-check demand. A role that does says so in its advert, and the card marks it.

Which companies hire most backend developers?

Coupang (21), Bjak (14), FuriosaAI (14), Danggeun Market (11), Next Securities (10).

Which roles count as backend developer jobs?

Every role whose work is the server side of software - backend, API, platform and full stack developers, staff engineers and technical leads - at any employer. A role is filed under a language when its title names one (Java, Python, .NET, Go, Node.js, PHP, C++, Ruby, Rust); a "Software Engineer" that names none is a backend engineer's.

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.
