Senior Executive Assistant - Munich

Job description

Reporting to - Max - CEO  

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. 

This is not a concept on a slide. Our first two SkyBee satellites have been in orbit since 2025, each flying a cryocooled thermal infrared instrument on a microsatellite, and our next satellites are already in the pipeline. Backed by a €37M Series A, we are now opening a new site in Munich to bring assembly, integration and test (AIT) in-house. 

With offices in Brussels, Freiburg, Munich, Berlin and Toulouse, our multidisciplinary team of engineers, scientists and strategists is turning flight data from orbit into the next generation of thermal satellites.
