Sr. Satcom Modem Engineer Verified today
About the Role
Planet is developing the next generation of small satellite buses with high-resolution optical imaging payloads, space-based data centers connected by optical inter-satellite links, and high-speed RF/Microwave communication links. We continuously iterate on and develop small spacecraft communication systems including board-level hardware, antennas, and ground station equipment to achieve record data rates and link performance.
As Sr. Satcom Modem Engineer, you will architect, design, simulate, implement, and validate cutting-edge software-defined Satcom radios. You will characterize SDR link performance of Planet's next-generation S through Ka-band and optical terminals, select vendors, and manage subcontractors for Satcom solutions. You will facilitate and conduct rigorous testing on space and ground communication subsystems to ensure flight readiness.
