You know that "it works" isn't enough. Integrations need to be reliable, maintainable and well-documented. * Quality-driven: CI/CD, TDD and clean code are daily practice for you. You write code that others can understand and build on. * Knowledge sharer: You don't just raise your own code, you raise the whole team. Code reviews, architecture discussions, pair programming: you share actively and make others better. * Product thinker: You don't just build what's in the ticket. You understand the customer problems behind an integration and bring technical insight into product decisions. Professional requirements: Strong in C# and .NET Core. Solid understanding of MongoDB, Docker, Kubernetes and cloud environments (GCP/Azure). Comfortable with CI/CD pipelines, TDD and agile development principles. AI coding tools like Claude or Cursor are part of your natural workflow. Fluent in English. Based in or willing to relocate to Hamburg. Bonus: Hands-on experience with billing/financial systems, event-driven architecture, and knowledge of the energy sector. ## Description * You understand our platform architecture, existing systems and tech stack (C#/.NET, MongoDB, Docker, Kubernetes, GCP/Azure) deeply enough to independently plan and ship features. * You've shipped your first significant feature in the billing/pricing backend or significantly improved an existing service. * The team values your input on architecture decisions. Month 6 (Performance) * You've delivered several services and integrations (e.g. pricing logic, billing, financial transactions) that are stable, scalable and well-documented. * You've refactored existing backend systems so they efficiently support new product lines and tariff models. * You've introduced code or process improvements that increased team quality or velocity. Month 12 (Scale) * You're the go-to technical reference for the backend architecture of our billing & pricing platform. * The platform is built so that new product lines, tariff models and pricing logic can be delivered with significantly less effort than before you started. * New engineers ramp up faster because you've shared knowledge, documented standards and set the bar., * Impact: When an invoice is correct and every kilowatt-hour is priced right, it's because of your code - not abstract infrastructure, but systems that directly reach the customer. * Ownership: You shape the backend architecture of our pricing team, not just the implementation. * Culture: Transparent feedback. We celebrate mistakes as long as we learn from them. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [40 Minutes to Build a Serverless COVID-19 REST and GraphQL APIs](https://www.wearedevelopers.com/videos/208-40-minutes-to-build-a-serverless-covid-19-rest-and-graphql-apis) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Finding Jobs in Germany](https://www.wearedevelopers.com/magazine/375-finding-jobs-in-germany) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023)
