About The Position

Millennium Space Systems, a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation. Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen. Millennium programs are reshaping the future Overhead Persistent Infrared (OPIR) enterprise for National Security Space customers, focusing on smaller, proliferated, and resilient systems across multiple mission areas. Millennium is establishing a resilient missile warning architecture that adds capability to global detection, warning and precision tracking of advanced threats, including hypersonic missile systems. As a Mission Architect, you will be an OPIR Subject Matter Expert (SME), overseeing mission architecture and spacecraft/constellation design across one or more programs. You will oversee all aspects of designing, developing, and fielding Remote Sensing (RS) space segments, including integration with ground and user segments. You will design and develop modeling and simulation tools and methods to validate mission scenarios and assess end-to-end system performance against Key Performance Parameters (KPPs). You will be responsible for assessing sensor design, development, and performance, conducting solution trades, and decomposing requirements for payload and algorithm vendors. You will be integral to writing proposals, requirements definition, system design, integration & test, and on-orbit operations.
