Company Description

Join us and make YOUR mark on the World!

Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are looking for individuals that demonstrate an understanding of working in partnership with team peers, who engage, advocate, and contribute to building an inclusive culture, and provide expertise to solve challenging problems.

Job Description

We have multiple openings for experienced Radio Frequency (RF) Engineers to work on projects and initiatives with a focus on U.S. national security. You will be a member of an engineering team that will provide space mission engineering solutions for both national security and basic science investigations in direct support of LLNL’s Global Security Directorate Mission areas. As our RF engineer, you will be responsible for modeling RF front end components such as Power Amplifiers, Low Noise Amplifiers (LNAs), diplexers, couplers, circulators, filters and antennas. You will model RF front end assemblies that can be leveraged across multiple platforms, simulate their operation in complex environments to understand performance in different conditions, and help perform validation measurements to correlate your models with actual data at the component and system level. This position is in the National Security Engineering Division (NSED) within the Engineering Directorate at LLNL.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role, you will 

  • Work as an integral part of a small team of scientists and engineers to develop technical proposals for spacecraft missions including communications subsystem and payload specifications, spacecraft subsystem electrical specification, and cost and schedule estimates.
  • Review, advise, and conduct complex analysis and development studies in support of programmatic goals, including analysis of novel or unprecedented problems as an information resource to system engineers.
  • Lead RF engineering design for spacecraft subsystems from conceptualization, simulation, part grade specification, layout, fabrication and acceptance testing.
  • Exercise technical knowledge of the limitations of proven concepts and practices on RF communication systems, equipment, and/or hardware to correctly evaluate alternatives or risk associated with using or replacing a nonconforming component for orbital requirements.
  • Understanding of transceiver requirements in satellite Telemetry, Tracking and Command (TT&C) subsystems
  • Utilize ADS, CST Microwave Studio, HFSS, Comsol and other RF & EM tools for the design of antennas and RF front end modules and sub-assemblies
  • Perform other duties as assigned

Additional job responsibilities, at the SES.3 level

  • Apply advanced RF engineering solutions and technical analysis to develop and implement creative solutions to resolve highly complex technical and programmatic issues.
  • Develop RF engineering path to flight vision and lead a team supporting spacecraft launch and early operations, maintaining spacecraft health and safety, optimizing performance, and troubleshooting anomalies.
  • Support mission planning functions, including design and analysis of spacecraft electrical requirements, electrical component assurance test plan and operational concepts.


  • Bachelor’s degree in RF/electrical engineering or related field, or the equivalent combination of education and related experience.
  • Comprehensive knowledge and experience with one or more of the following systems and subsystems: TT&C, communications, and RF sensing systems.
  • Experience working as a member of a multidisciplinary project team that may include engineers, scientists, designers, and technicians
  • Experience devising solutions for complex problems that require in-depth analysis of tangible and intangible factors.
  • Advanced verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information to colleagues, management or sponsors.

Additional qualifications at the SES.3 level

  • Significant knowledge of highly advanced concepts related to aerospace and/or electrical engineering of spacecraft and demonstrated experience leading the development of proposals to meet space mission customer requirements.
  • Significant experience and demonstrated track record of success developing and implementing creative solutions to a diverse range of highly complex multi-disciplinary problems and leading corrective actions where necessary.
  • Experience effectively managing multiple parallel tasks, often requiring the resolution of conflicting work requirements and prioritization of tasks toward predetermined long-range targets, and experience estimating cost and schedule of projects.

Qualifications We Desire

  • PhD degree in RF/electrical engineering or related field, or equivalent combination of education and experience.
  • Demonstrated knowledge of space mission engineering principles, practices and application in electro-optical system analysis and design in either laser or imaging systems.
  • Aerospace and/or spacecraft engineering experience with designing, assembling or testing flight hardware.
