You will also be preparing, reviewing and handling deployments (servers or services). At some point, you will have to deal with some L3 support requests. 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.

We are dealing with an intensive heavy production setup handling tens of thousands users. All our setup are redundant and resilient. We’ll get bigger and bigger, whatever!

The team

We are a small group spread globally and we work closely with cloud team which handles the development of our cloud and online services. Communication will often be asynchronous in nature and we heavily rely on gitlab to keep track of day to day activities. We encourage everyone to participate in planning the road-map for how we can make our infra more reliable.
