Position: Experienced RF Engineer (Colorado)

Description

As we enter a new era of Strategic Weapon Systems, Lockheed Martin is a pioneer, partner, innovator and builder. Our amazing men and women are on a mission to make a difference in the world and every single day we use our unique skills, talents and experiences to design and build solutions to some of the world’s hardest engineering problems. Do you want to be part of a culture that inspires employees to envision the impossible, perform with excellence and build incredible products?

We provide the resources, inspiration and focus—if you have the passion and courage to dream big, then we want to build a better tomorrow with you.

Bring your experience and passion for engineering to Lockheed Martin, and build the systems which support our nation's defense systems.

We are seeking a highly motivated RF Engineer to support the design, development, and integration of advanced radio frequency systems for space-based applications. In this role, you will contribute to the end-to-end lifecycle of RF payloads and subsystems, including Earth‑Space Antennas (ESAs), satellite communications links, and RF front‑end electronics. You will collaborate with systems engineering, digital processing, and integration/test teams to deliver high-performance RF solutions that enable secure and reliable mission success in space environments.

What

does this role look like?

• Design, model, and analyze space RF systems including ESAs, phased array antennas, transponders, transmitters, and receivers.
• Perform link budget analysis for Earth-to-Space, Space-to-Earth, and inter‑satellite communications.
• Support RF payload architecture trades, including power, bandwidth, gain, and coverage optimizations.
• Develop and verify RF hardware performance using simulation tools (HFSS, ADS, CST, MATLAB) and laboratory/field test equipment (spectrum analyzers, VNAs, anechoic chamber measurements).
• Collaborate with antenna engineers on the design, test, and integration of reflector and phased‑array antennas.
• Define and validate requirements to ensure compliance with mission performance, environmental, and radiation constraints.
• Document technical results and present findings at internal design reviews and with external customers.

Important Notes

• Candidates may be subject to a government security investigation and must meet eligibility requirements for access to classified information.
• Applying to this Expression of Interest opportunity introduces you to Lockheed Martin's job opportunities and promotes you to managers who are interested in hiring for multiple roles.
• You can’t and will not be hired on this requisition. Actual job responsibilities, levels, and locations will vary based on actual hiring job postings.

Basic Qualifications

• Bachelor’s degree (or higher) in Electrical Engineering, Physics, or related discipline.
• Knowledge of RF/microwave design principles, including transmission lines, wave guides, impedance matching, and antenna fundamentals.
• Hands‑on experience with RF test equipment (spectrum analyzer, VNA, signal generator, power meter).
• Familiarity with satellite communications or space RF payload development.
• Active Top Secret clearance with the ability to obtain and maintain a Top Secret/SCI clearance.

Desired Skills

• 2+ years of experience in space RF system design, analysis, or test.
• Proficiency in RF simulation tools such as HFSS, ADS, CST, MATLAB, or Simulink.
• Experience with Earth‑Space Antennas (ESAs), phased arrays, reflectors, or electronically steered antennas.
• Understanding of communication system design, modulation schemes, coding, and link budgets.
• Familiarity with radiation, thermal, and reliability constraints for space‑qualified hardware.
• Hands‑on experience with antenna testing in anechoic chambers.
• Strong communication skills with the ability to convey technical concepts to leadership and customers.
