Job ID: 730599BR Date posted: May. 31, 2026
Description:Lockheed Martin is a global security and aerospace company that employs approximately 114,000 people worldwide and 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 Missiles and Fire Control (MFC) is seeking a Principal RF Engineer to serve as the senior technical authority for RF system architecture, design, and performance across a portfolio of advanced sensors, EW payloads, and weapon-system effectors.

MFC is a recognized designer, developer, and manufacturer of precision engagement aerospace and defense systems for the U.S. and allied militaries. This role is suited for a recognized expert who shapes RF technical direction at the business-area level, serves as a prime consultant to MFC leadership, and represents the organization to customers and the broader defense RF community.

What You Will Be Doing

The Principal RF Engineer will serve as a recognized subject matter expert and one of the most senior individual technical contributors within RF Engineering, providing architectural leadership, strategic direction, and personal execution on the most technically challenging RF problems.

Responsibilities may include:

• Setting RF technical direction across multiple programs and IRAD efforts, owning long-range RF capability roadmaps and technology maturation strategy

• Serving as a prime consultant to top management on RF capture strategy, technical baselines, and investment prioritization with material impact on design/selling success, financial posture, and product portfolio decisions

• Personally leading the most technically demanding RF design, architecture, and analysis problems—from concept and trade-space exploration through fielding

• Driving RF system-of-systems architectures and multi-domain integration (EW, SIGINT, communications, RADAR), including next-generation multi-function aperture and contested-spectrum solutions

• Owning competitive capture leadership for major RF efforts, including technical volume authorship, BOE development, and competitive technical strategy on programs

• Representing RF Engineering to senior customer executives, external technical communities, and corporate technical leadership; influencing technical strategy at the business-area, sector, or corporate level

• Establishing and evolving engineering processes, standards, and tools that measurably improve organizational RF capability

• Mentoring staff-, senior-staff-, and emerging-principal-level RF engineers; identifying and developing future technical leaders

• Leading or contributing to cross-Business Area and cross-corporate technical initiatives (e.g., Engineering Technical Council, Communities of Practice, Technical Fellow programs)

• Driving advancement of the state of the art through patent disclosures, peer-reviewed publications, and professional society leadership (e.g., IEEE MTT-S, AP-S, AESS)

This position offers the opportunity to set the long-term technical direction of RF engineering at MFC and to shape the workforce and technical capability for the next decade of mission needs.
