Green Fusion is a 100-person climate tech company optimizing heating systems at scale across Germany, with expansion into France. We connect to building infrastructure via proprietary hardware, collect real-time data, and deliver energy savings through algorithmic optimization.
We’re transitioning from fast, early-stage execution to a more structured, product-led engineering organization and need help making that shift work in practice.
As VP of Engineering, you will partner up with our CTO, CPO & CEngO to take our technology organization to the next growth level. You’ll own how we develop across all tech teams and bring the structural clarity our growing organization needs. You’ll have clear decision-making authority over engineering processes, standards, and team structure, in close partnership with the CTO.
