Office Assistant (m/f/d) part-time (20 hours/week)

Who We Are

Cities are living systems - and trees are some of their most valuable assets. At greehill, we’re building the world’s most detailed digital twins of urban forests, mapping every individual tree in a city in 2D, 3D, and beyond.

By combining cutting-edge laser scanning, AI, and machine learning, we give cities the insights they need to maintain, protect, and grow their green infrastructure. The result? Smarter operations, healthier citizens, and cities that are more resilient to climate change.

We’re helping redefine what “smart cities” really means - and we’re doing it globally, with teams in Budapest (HQ & R&D), Singapore, Hannover, San Diego or Paris.
