Space communications systems and payloads for defense and commercial missions
CesiumAstro designs and manufactures RF systems, phased arrays, and satellite payloads for LEO, GEO, airborne, and lunar platforms. The tech stack—Vivado, SystemVerilog, FPGA/ASIC design, DSP, plus mechanical simulation (ANSYS, Thermal Desktop, LS-DYNA)—reflects deep hardware engineering. Hiring is heavily weighted toward senior and principal engineers (210 of 260 roles), indicating a company scaling production and next-generation product lines while managing tight constraints around mass, cost, and reliability across multiple concurrent missions.
