About the Role
Planet is developing next-generation small satellite buses, featuring high-resolution optical imaging payloads, a space-based data center, and high-speed communication links. We are seeking an experienced Satcom Modem Engineer to develop and mature our next-generation onboard satcom links, ground radios, and antenna systems. You will architect, design, simulate, implement, and validate cutting-edge software-defined Satcom radios, characterize SDR link performance, select vendors, and manage subcontractors. You will also facilitate and conduct rigorous testing on communication subsystems to ensure flight readiness. Success requires close collaboration with RF, EE, Flight SW, systems engineering, missions, and manufacturing teams. The ideal candidate thrives in an agile, fast-paced environment and is comfortable with ambiguity.
