Working with us also mean you are comfortable working in an only open source environment.

Ansible, docker and CI/CD automation are the cornerstone of our setup. Here are major tools and technologies spread over all our stacks : mariadb, maxscale, ldap, nginx / php, haproxy, dovecot, postfix, rspamd, gitlab, nftables, elasticsearch stack, wazuh. Of course, already knowing these is a plus.

The team
