Siemens is a German technology conglomerate founded in Berlin in 1847 by Werner von Siemens around a telegraph that indicated letters rather than Morse code. After a decade of divestments it now concentrates on industry, infrastructure, transport and healthcare, supplying factory automation and control systems, building and grid technology, trains and signalling, and the Teamcenter and NX design software acquired through a long run of software purchases. The Siemens Xcelerator platform ties hardware to software and digital twins, and the group retains a majority stake in the separately listed medical imaging company Siemens Healthineers.

Questions

Can a foreigner apply for these roles?

76 of the 79 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?

Groupe SII (10), Sopra Steria (9), CS Group (8), Meritis (7), Dassault Systemes (6).

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.
