RF Systems Engineer, Sr; PhD - Orlando FL

Description

Lockheed Martin is a global security and aerospace company that employs approximately 114,000 people worldwide. The company is principally engaged in the research, design, development, manufacture, integration, and sustainment of advanced technology systems, products, and services. Lockheed Martin Missiles and Fire Control (MFC) is one of four Lockheed Martin business areas.

Lockheed Martin is seeking an RF Systems Engineer with RF design, analysis, and test experience.

The RF Systems Engineer will generate modeling/simulations for advanced control systems, build and test prototype hardware in the lab, and collaborate with a larger team for flight hardware configurations. Specific duties may include assisting engineers with antenna modeling, RF system modeling and requirements development, and working closely with systems and design engineers to identify key RF hardware requirements that meet mission needs.

The role involves constructing models for simulation and utilizing a wide range of test equipment such as power supplies, DMMs, oscilloscopes, RF power meters, frequency generators, spectrum analyzers, and network analyzers. Experience with MATLAB modeling is required.

We are committed to supporting your work‑life balance and overall well‑being, offering flexible scheduling options. Learn more about Lockheed Martin’s comprehensive benefits package here.
