System Engineering

Because it is the only way in which we can guarantee the necessary levels of control, integrity and security, Kolab Systems is running its own data centre operations, with hardware that it owns and a state of the art virtualised/atomic infrastructure that it maintains itself. The purpose of this infrastructure is production usage by our own staff, as well as servicing the public Software as a Service (SaaS) offering behind Kolab Now, in particular. 

There is a variety of roles in system engineering in Kolab Systems, working closely with our developers, our customer support team, our customers on advanced deployments and other tasks. It is a field where a variety of options for personal development exist, and besides all the other aspects of what it means to work for Kolab Systems, we encourage our system engineers to build their portfolio and expertise. 

The technical stack for Kolab Systems itself is largely built around the Red Hat Enterprise Linux (RHEL) family of systems, and we work closely with Red Hat also in our development of new technologies as a trusted Advanced Technology Partner and Development Partner. But we have close ties to all the communities, including SLE, Fedora, openSUSE, Debian, Ubuntu, and Kolab is used on all these platforms.

So we are explicitly looking for people with expertise in any of these platforms.
