We are looking for Linux Infrastructure Security Expert (m/f/d) that helps us build a modern, resilent and secure platform used by hundreds of engineers accross the R&D organization.
This role is intended for senior engineers with experience with internal and external cloud infrastructures in a linux environment.
WHAT YOU'LL DO
