Engenheiro Backend (m/w/d) - Pricing

Rabot Energy is an independent provider of dynamic electricity tariffs with 100% green energy. Through our innovative procurement strategies, we ensure both ecological sustainability and cost optimization in home energy management. By passing on wholesale electricity market prices directly to our customers, we are able to reduce their electricity bills by an average of 35%.

Owners of electric vehicles and smart meters benefit particularly from our dynamic electricity tariff, as they can automatically charge their vehicles at home when electricity prices on the exchange are especially low. In the Rabot Energy app, charging preferences can be easily set and current market electricity prices can be tracked in real time.

With our intelligent charging solutions, we actively contribute to increasing the share of renewable energy in Germany's overall electricity consumption.

Our vision is to give every customer the opportunity to manage their energy consumption in a smart way while conserving the environment and natural resources. By offering smart charging and energy management solutions, Rabot Energy actively helps drive the energy transition forward. With this idea, we have already won the trust of over 100,000 customers.

Why Now?

The energy market is going through its biggest shift in 50 years. We no longer just manage electricity, we make it intelligent. RABOT is growing triple digits. We have the product, we have the market fit, now we need you to take the engine to full speed. We're not looking for administrators, we're looking for architects of our growth.

Your Mission

Every kilowatt-hour RABOT delivers to customers has to be priced, billed and processed correctly in real time. Dynamic tariffs, different product lines, growing customer numbers: our billing and pricing systems are the financial backbone of the company. You own the "source of truth" of our business.

Your job is to build the bridge between abstract energy data and precise financial execution. You develop and scale the backend services that process complex pricing logic and financial transactions. You work independently on hard problems, bring architectural vision, and help the team scale through clean code, solid patterns and shared standards. You're not just a developer - you're the guardian of our platform's reliability.

Your Results

We think in outcomes, not task lists. If you're successful, here's what that looks like:

Month 3 (Ramp-up)

• 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.

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
