If you are an experienced systems engineer with a background in space systems architecture and design, and have at least 8 years of experience, you will be excited about the Senior Systems Engineer opening with Iridium on our SDA (Space Development Agency) Project. As a Senior Systems Engineer, you’ll be responsible for interfacing between the Iridium Operations team supporting the SDA and the Iridium System Engineering team in developing artifacts associated with the operations of the mesh network and ground segment. You will provide critical operations and integration support to improve our efficiency and effectiveness by implementing processes, procedures, checklists, and software tools for ground and satellite operations. Working in this role, you’ll interface with the U.S. government in dealing with Iridium generated and delivered System Engineering documents that govern operations at the SDA operation centers. You’ll also be responsible for the design, development and maintenance of functional on-orbit test procedures, working with multiple satellite vendors to ensure synergy of on-orbit tests, assist the SDA in the development of operational test procedures, and act as a liaison between the space contractors, ground contractors and government team during operations. You will work 12-hour shifts with a team onsite in a 24/7, multi-satellite operations environment. You will thrive in this role if you enjoy tackling complex challenges and working in a fast-paced, dynamic environment.
