This is what our colleagues say
“Creativity, team orientation, sustainability - you don't immediately associate these qualities with Software Development. But here at Next Kraftwerke, they all come together: As a team, we develop creative ideas and solutions and implement them successfully as part of the digital energy revolution. Flexible working hours give me the freedom to develop professionally while also taking care of private activities.”
