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. As a Spacecraft Systems Engineering Intern, you will be supporting the technical execution for programs, as well as supporting teams in the development of spacecraft systems serving a range of missions and customers. This includes assisting the monitoring and guiding of requirements definition, spacecraft design, procurement and fabrication, integration and test, and verification and validation of the overall space vehicle system. You will interact with subsystem and product engineers, manufacturing and test personnel, and program management. You will engage with the technical elements of the space vehicle system. Our spacecraft systems engineers create spacecraft -- not just paperwork! Over the course of our 10-12 week internship experience you will have the opportunity to: Responsible for supporting spacecraft systems engineering, including performing interface management and validation, requirements verification and validation, support to integration and test operations, anomaly resolution, risk management, and schedule execution Apply an interdisciplinary, collaborative approach to assist in the planning, design, development and verification of a lifecycle balanced solution for space systems Understand spacecraft subsystems functions and interfaces. Assist in the development of integrated spacecraft system designs and solutions Coordinate and communicate with subsystem engineering teams to ensure system execution Apply model-based systems engineering techniques for the definition of the spacecraft system Participate in software integration and test activities to ensure mission functionality prior to deployment into operations Perform tasks to analyze technical data, assist in the verification of specific systems configurations in accordance with defined constraints and operational requirements Assists in the resolution of cross-functional technical issues This position is expected to be 100% onsite.
