Role
Who you are
- Pragmatic generalist: You move from a CSS tweak to a backend API optimization to an LLM prompt refinement in a single afternoon. Full-stack isn't a label for you, it's how you think
- Business mind: You ask "Should we build this?" before "How do we build this?" You understand CAC, LTV and why user experience is the ultimate competitive advantage
- High agency: You don't wait for a perfectly groomed Jira ticket. You find problems, talk to stakeholders and ship solutions. If something is unclear, you clarify it. If something is broken, you fix it
- Knowledge sharer: When you discover a workflow, prompt pattern or architectural shortcut that works, you make it available to the team. Building alone is fast; building so others can follow is lasting
- Professional requirements: Solid command of React (TypeScript) and C#/.NET. AI-assisted coding with tools like Claude and Cursor is a core part of your workflow, not an experiment. You have shipped products or side projects that prove you can deliver end-to-end
What the job involves
- The intersection of energy and AI is the new frontier. RABOT doesn't just want to "use" AI; we want to integrate it into the core of how customers interact with energy. Intelligent savings predictors, natural-language energy insights, features that make our product feel like magic: someone needs to build them. End-to-end, from napkin sketch to production
- You are that person. A "squad of one" when needed and a collaborator always. You bridge the gap between complex energy data and intuitive user experiences. You move across the full stack (React, C#, Flutter), prototype fast and ship faster. You use AI tools not just to write code, but to build features that were previously impossible
- Month 3 (Ramp-up):
- You've shipped your first end-to-end feature across the full stack
- You've identified an area where AI can optimize our internal workflows or customer-facing product
- Month 6 (Performance):
- You have launched a major product initiative from initial sketch to production
- You've demonstrated how AI-assisted engineering allows you to outpace traditional development cycles
- Month 12 (Scale):
- You have built a suite of intelligent features that tangibly improved customer retention or conversion
- You have set the standard at RABOT for how business-savvy engineering creates market value
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.
