## About the Role

You are driven by impact and know how to turn strategy into execution. You're used to fast-paced environments and thrive when given clear goals and high accountability. We believe you'll thrive here if you:

 * Are proactive and entrepreneurial, comfortable owning your work end-to-end in a small, high-impact team
 * Communicate well with both technical peers and business stakeholders
 * Have a background in energy, utilities, or financial markets, or experience with .NET - a plus, but not required
 * Tibber becomes more AI-enabled and we embrace new tools and ways of working. You don't need to be an expert, but we believe you are motivated by that and excited to grow with it too
