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 and designing Interface Control Documents (ICDs) and Interface Design Documents (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's primary responsibility will be developing , updating, and maintaining multiple ICDs and IDDs. Successful candidate will attend interface working group meetings with the external 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 Missile Defense Systems Elements, support requirements engineering, use case development, and logical architecture modeling tasks as SE department tasking requires. The Interface Engineer will support leadership (internal and external), developers, and testers with messages and interface rules (transmit, receive, processing) questions and test findings. Please Note: -This position requires a government security clearance; you must be a U.S. Citizen for consideration. -The role will involve approximately 10% travel to customer sites throughout the U.S. As leaders of the C2BMC team, Lockheed Martin partners with industry leaders to develop and field the backbone of America’s missile defense. Our national team supports the design, development, testing, integration, and fielding of hardware and software elements essential for the effective operation of the Missile Defense System (MDS).
