Open positions at Seven2one

At our company, a DevOps Engineer is more than just a DevOps Engineer. That’s because we develop more than software – our work drives the energy transition.
We are more than happy to make use of any technology that moves us forward. The only thing we don’t have any use for are fixed and entrenched categories and classifications. We are constantly moving between the worlds of cloud-native, on-premises and hybrid. We work with external service providers when we need to make use of special core expertise, and we operate systems independently when they are mission critical. As a DevOps Engineer, you’re used to pushing the boundaries of what is possible – and in our IT infrastructure, you can push them to the limit. How exactly is that possible? You can find out here in the job offer.

At our company, a Senior Software Developer is more than a Senior Software Developer. That’s because we do more than just develop software. We are also driving the energy transition forward with our ideas, tools and platforms.
Because the energy market is highly complex and dynamic, with something new happening nearly every day, we are always doing our work on the cutting edge of technology. On an interdisciplinary basis, with 47 individuals with bright minds and a passion for what they are doing. Perhaps you could also join us in this endeavour soon? We are looking forward to meeting you and getting to know your ideas and expertise! Find out more about us and our job openings here.
