Global SE - Interface Engineer; Secret Clearance

What We’re Doing

Our team, the Command and Control, Battle Management and Communications (C2

BMC) 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. 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 authoring the development of ICDs and IDDs, establishing new interfaces between external elements, including sensors, and other command and control systems. They will ensure that ICDs and IDDs meet appropriate program standards, develop behavioral diagrams, create requirements captured in DOORS, and update multiple interface control documents. The Engineer will attend interface working group meetings with the MDA customer and external element engineering organizations, support program integration, test efforts, and may assist other interface engineers with ICD development, requirements engineering, use‑case development, and logical architecture modeling.

They will also support spiral leadership to assure interface artifacts and system assessment tasks are completed on schedule.
