As a Sr. Radar Systems Engineer at Lockheed Martin within the Engineering & Design organization, you will play a key technical role in the architecture, design, integration, and optimization of advanced radar solutions that support critical defense and aerospace missions. Working at the intersection of RF engineering, signal processing, and systems engineering, you will help define concepts of operation, translate mission needs into system requirements, develop and analyze radar algorithms, and guide designs from initial concept through lab integration, flight test, and sustainment. You will collaborate closely with multidisciplinary teams including RF and digital hardware engineers, firmware and software developers, systems architects, and test engineers to create radar systems that meet demanding performance, reliability, and survivability requirements. Responsibilities will include leading radar system trades and performance analyses, modeling and simulation of detection and tracking performance, supporting waveform and signal processing algorithm design, conducting system-level integration and troubleshooting, and supporting verification and validation against customer specifications and military standards. You will also provide technical guidance and mentorship to junior engineers, participate in design reviews, and contribute to technical proposals and customer briefings. In this senior role, you will help ensure that radar subsystems integrate seamlessly into larger mission systems, coordinating with platform, sensor fusion, and command-and-control teams. You will support lab and field test activities, including test plan development, test execution, data analysis, and generation of test reports and technical documentation. A strong foundation in electrical or aerospace engineering, radar theory, and modern digital signal processing is important, along with experience on complex, safety- or mission-critical systems. Familiarity with tools such as MATLAB/Simulink, modeling and simulation environments, and requirements management and configuration control systems will be valuable. Lockheed Martin focuses on the research, design, development, manufacture, integration, and sustainment of advanced technology systems, products, and services, and emphasizes strong ethical standards, inclusivity, and teamwork. As part of this culture, you will operate in an environment that values integrity, innovation, and diverse perspectives, working with colleagues who are passionate about solving complex technical challenges in support of national security and aerospace leadership. The company offers a wide range of career opportunities, with the potential to grow into technical leadership, architecture, or program roles as you expand your expertise. This position typically requires substantial experience in radar systems or closely related sensor systems, along with at least a bachelor’s degree in electrical engineering, computer engineering, aerospace engineering, or a related discipline. An advanced degree is strongly preferred for senior-level impact. Many programs will require the ability to obtain and maintain a U.S. government security clearance, and prior work on Department of Defense or aerospace programs is highly desirable. You will be expected to communicate complex technical concepts clearly to both technical and nontechnical stakeholders, contribute to continuous improvement of processes and tools, and embody Lockheed Martin’s mission-focused mindset. Lockheed Martin offers a comprehensive total rewards package that may include competitive base salary, performance-based bonus opportunities, retirement savings plans such as a 401(k) with company contributions, and a range of health and wellness benefits that typically encompass medical, dental, vision, and life insurance options. The Sr. Radar Systems Engineer role is generally a full-time position with a primarily hybrid work environment, balancing on-site lab and integration activities with remote analytical and documentation work, depending on program and customer needs.
