Overview
Principal Narrowband Communication Systems Engineer I at CesiumAstro. We design, build, and deploy space and airborne communication systems. We are seeking a highly motivated, independent problem-solver to own the design, configuration, and operation of the satellites space-to-ground TT&C systems, defining how the satellite communicates with the ground in nominal and off-nominal conditions to ensure reliable command, telemetry, and fault recovery. Please note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee, or eligible to obtain the required authorizations from the U.S. Department of State. Responsibilities
Own the RF Link Model, analyze and maintain the satellites link budget, modulation and coding, ensuring reliable communications from space to ground. Select & Configure Hardware Define and implement the TT&C radios, antennas, and modems best suited for the mission. Develop Operational Concepts Define how the radios are used in different mission phases, including contingency operations and emergency recovery. Integrate & Test Work with flight software and ground teams to validate end-to-end TT&C performance, from antenna to command center. Solve Hard Problems Optimize low-SWaP communications, mitigate interference, and ensure robust, fail-safe links. What a Successful Candidate Looks Like
Youre an RF Systems Expert You understand how to design, analyze, and operate space-to-ground communication links. You Think in Link Budgets You can balance power, bandwidth, protocols and noise to ensure reliable space-to-ground connectivity. You Understand Satellites You know how comms fit into the broader mission, from flight software integration to ground operations, taking ownership of capability up to subsystem boundaries. Independent self-starter You are comfortable identifying problems and using your expertise to pathfind solutions. You Move Fast You can prototype, test, and iterate quickly, focusing on whats needed. Job Requirements and Minimum Qualifications
