Our Mission At constellr, we're harnessing the power of space to solve one of Earth’s greatest challenges: climate resilience &amp; 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 observationYour Role We are seeking a highly motivated Payload System Engineer to join our spacecraft engineering team. Reporting to the Satellite Systems Lead, you’ll be part of the Mission and Space Systems team. You’ll collaborate daily with the other engineers on the team, as well as the operations teams and external partners.
