Senior Software Engineer (m/w/d) - Billing & Pricing Platform

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.

Who We Are Looking For

• Systems thinker: You think in distributed systems, API design and scalability, not individual endpoints.
• Integration pro : You have experience connecting external systems, APIs and hardware providers. 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.

What We Offer

• 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.

Your Extras

• Employee discount on RABOT Energy electricity tariff
• Urban Sports Club partnership + Deutschlandticket
