Role
Who you are
- Autonomous engineer: You take deep ownership of your domain. You don't wait for a ticket; you identify what needs to be built and you execute. You have the architectural vision to see the big picture and the builder mindset to enjoy the implementation
- Knowledge sharer: You don't just raise your own code, you raise the whole team. Sharp code reviews, architecture discussions, Backend Chapter work: you share actively and make others better
- Analytical communicator: You distill complex backend challenges into clear narratives for your team and stakeholders. You are resilient, structured and thrive when the stakes and the growth are high
- Pattern-driven thinker: Your eyes light up when discussing DDD, CQRS and Clean Architecture. You have a deep appreciation for software patterns and know that "done" includes being maintainable and well-tested
- Professional requirements: Strong command of C# and ASP.NET. Solid understanding of SQL (EF Core), API design, microservice architecture and async messaging (e.g. RabbitMQ, Azure Service Bus). Agentic AI-assisted coding is a core part of your workflow. You use tools like Claude Code to move faster and focus on high-level design
- Bonus: DDD, CQRS, TDD, Clean Code Architecture, gRPC or full-stack experience
What the job involves

You are not just a coder; you are a guardian of our platform's reliability

Our take
To support the transition to renewable energy, Rabot Charge supplies AI-powered dynamic tariffs that enable consumers to use electricity when it is its cheapest. This is more environmentally friendly because it also corresponds to when more solar and wind power is available.
The company enables this because it buys electricity at short notice via the day-ahead and intraday energy markets, allowing it to make use of hourly price fluctuations. Rabot's customer can power large appliances or charge their electric vehicles when prices are at their lowest, thus saving them money on their energy bill. This also means that more households can access renewable power without major changes to their energy usage habits.
Although it is not the only company delivering dynamic pricing for electricity, Rabot Charge has seen consistent investment over the years which suggests it is doing something right. The 2025 influx, led by Bosch, will support the further development of its algorithm to enhance its ability to find the best prices.
