NIEUW Where: Fully on-site in Mons, Belgium (NCI Agency at SHAPE). Would you like to join the leading international intergovernmental organisation? NATO's Cyber Security Centre is one of the largest integrated cyber-defence capabilities on earth, 250+ analysts and engineers defending 100+ sites across all 32 member nations. Every one of those defences runs on Linux, and the Alliance is looking for a hands-on Linux Engineer to keep that foundation rock-solid. This isn't a ticket-closing seat. You'll own the RHEL servers and the complex infrastructure that the Centre's cyber services depend on, building them, hardening them, and automating them with Ansible and Python so they run clean and secure at scale. You'll work shoulder-to-shoulder with the people who defend NATO in cyberspace. What you'll do - Install, configure and maintain Linux servers end-to-end, with a strong focus on RHEL - Automate everything you can with Ansible and Python - Harden systems, firewalls, encryption, access control, to security best practice - Work across virtualisation (VMware) and a DevOps toolchain - Understand how the whole stack fits together, from application to container to network to infrastructure
