We are looking for Engineers (m/w/d) who love the software work, but who see customer success as the top goal. With us you are not an anonymous coder, but technical ambassadors and problem solvers. Your home port is our location in Dortmund. We love flexible work, but we appreciate the proximity. We are looking for someone who lives in the Dortmund area to watch regularly for sprints, brainstormings or a cold drink in the office – without travel stress. .

Your tasks • Your profile • What we offer
AI-Enhanced Development: We strongly rely on Claude and state-of-the-art LLMs to accelerate our workflow. For you, AI-Pair programming is not a “Hexenwerk”, but a strategic tool. You are using Claude & Co. for architecture impulses, refactorings and efficient coding without losing the critical distance and final quality control. Technological sovereignty: Java and Spring boat are often the set standard of our customers – and you can control them blindly. At the same time, you are willing to proactively introduce modern alternatives such as Kotlin, Quarkus or Ktor when You advance the project and fit into the customer's strategy. End-to-End & DevOps: “Works on my machine” is not available to you. You accompany the code from architecture to stable operation in the cloud (preferably Azure). CI/CD and Infrastructure as Code are tools for you to secure the delivery capacity for the customer.
Long-standing experience in professional software development in the JVM environment. You know the Enterprise Standards (Spring) as well as modern, lightweight approaches. Experience with cloud native architectures (ideally Azure) and a deep understanding of DevOps processes. You are a team player, also in mixed structures and the work in heterogeneous teams is of course for you. That you engage in strange environments and communicate at eye level is not an obstacle to you, but the key to success. You think in MVPs and feedback loops. You know when perfectionism is appropriate and when a pragmatic approach brings the customer to the target more quickly. You know that “the customer is king” advises technically sound, but also accepts the framework conditions and legacy structures of the customer to make the best of it. You feel at home in the backend, but you have no fear of touch with modern frontends (TypeScript, Angular, React) or desktop solutions via Electron. You can explain complex issues in a comprehensible way – in-house as well as with the customer in German (C1 level) as well as English. Nice to have Experience in software architecture Knowledge of security or API design (e.g. GraphQL) First experience in the integration of AI/ML services
With us, Benefits are not a Buzzword-Bingo, but things you notice in everyday life. Work as it fits you Remote, in the office or hybrid – you decide what works for you. There are also flexible working hours, sliding time and overtime compensation. Work should adapt to your life, not vice versa. Time to learn With personal slacktime and a self-learning budget, we will give you room to try new things, stay up and develop you. Healthy through everyday life Health is more than a fruit basket in the kitchen or free water. We support you with a job bike, health days, ergonomic workstations and a grant for the gym. Good tied Our locations in Nuremberg and Dortmund are great to reach and offer everything that makes everyday work more pleasant – from a good (ÖPNV) connection to food trucks. Keeping on the go If you're regularly in the office, we'll take your Deutschlandticket. Mobile, simple and good for the climate. Team & team Whether it's a summer party, a Christmas party, a game evening, a lean breakfast, a barbecue or a bowling: we like to come together. Everything can, nothing has to. It feels good. Area for development Regular employee development talks belong to us. Not as a mandatory date, but as an honest exchange of what's going well and where you're going. We care how you feel Our own employee experience unit consciously cares that people feel comfortable with conplement and like to stay – in everyday work as well as beyond. .
