Our Mission

At constellr, we're harnessing the power of space to solve one of Earth’s greatest challenges: climate resilience & security in a changing world. Our thermal satellite constellation delivers the most accurate land surface temperature data on the market, equipping commercial players, governments, defence agencies, and global institutions with the thermal intelligence they need to make strategic decisions– from national security and infrastructure to agriculture and climate resilience.

As a fast-scaling company with offices in Brussels, Freiburg, Munich, Washington and Toulouse, our multidisciplinary team of engineers, scientists, and strategists is building the future of space-based Earth observation

Location: This position is offered on a hybrid or remote basis in Germany, Belgium, France, Spain, and Italy. We have offices in Munich, Berlin, Freiburg (Germany), Brussels (Belgium), and Toulouse (France). Occasional travel for team meetings & suppliers should be expected. We are open to considering remote working across Europe for exceptional candidates with a high level of experience.
