Our team, the Command and Control, Battle Management and Communications (C2BMC) team at Lockheed Martin, is dedicated to engineering, developing, and integrating new capabilities for the Missile Defense System that protects the United States and its allies. While we are part of a large organization, we operate within smaller, agile teams in a fast-paced, dynamic environment. Our responsibilities include Sensor/Weapon Integration, Algorithm Development, User Interface Development, Automated Testing, Cyber Security, and enhancing critical missile defense technologies. The Interface Engineer will lead in authoring the development of ICDs and IDDs. This includes establishing new interfaces between external elements, including sensors, and other Command and Control Systems. The Interface Engineer will ensure the ICDs and IDDs created are to appropriate standards required of the program. Additionally, it is expected that the Interface Engineer develop various behavioral diagrams to understand and document the requirements. The Interface Engineer will create requirements, captured in DOORS and at sufficient detail to provide clear understanding to the implementation teams. The Interface Engineer's primary responsibility will be developing and updating of multiple Interface Control Documents (ICDs) and Interface Design Documents (IDDs). Successful candidate will attend interface working group meetings with MDA customer and representatives of assigned external element engineering organization as well as support to program integration and test related efforts for the associated interface. Successful candidate may also be assigned to support: other interface engineers in developing ICDs for other BMDS Elements, support requirements engineering, use case development, and logical architecture modeling tasks as SE department tasking requires. Successful candidate will support spiral leadership to assure interface artifacts and system assessment tasks required for the assigned sensor interface are completed when required.
