Senior Principal Rf Engineer information

What are the key skills and qualifications needed to thrive as a senior principal RF engineer, and why are they important?

To thrive as a Senior Principal RF Engineer, you need deep expertise in RF circuit design, electromagnetic theory, wireless communications, and typically an advanced degree in electrical engineering. Proficiency with RF simulation tools like ADS or HFSS, network analyzers, and industry certifications such as IEEE or FCC compliance are commonly required. Excellent problem-solving, leadership, and communication skills help in guiding teams and collaborating with cross-functional stakeholders. These skills ensure the reliable design and implementation of complex RF systems essential for cutting-edge telecommunications and electronics projects.

What is the difference between Senior Principal Rf Engineer vs RF Systems Engineer?

AspectSenior Principal Rf EngineerRF Systems Engineer
CredentialsTypically requires advanced degrees (BSc, MSc, PhD) in Electrical Engineering or related fields, with extensive RF certificationsUsually holds a bachelor's or master's degree in Electrical Engineering, with some RF certifications
Work EnvironmentFocuses on high-level RF design, system architecture, and leadership in R&D teamsInvolves RF system integration, testing, and troubleshooting within product development teams
Industry UsageCommonly found in telecommunications, aerospace, and defense industriesUsed across wireless communications, consumer electronics, and network infrastructure sectors

The Senior Principal Rf Engineer typically holds more advanced credentials and leads complex RF projects, focusing on system-level design and strategic development. In contrast, RF Systems Engineers often work on implementing and testing RF systems within project teams. Both roles are essential in RF engineering but differ mainly in seniority, scope, and responsibilities.

What is a senior principal RF engineer?

Senior Principal RF Engineers are highly experienced professionals who lead the design, development, and optimization of radio frequency (RF) systems and components. They play a critical role in projects involving wireless communications, radar, satellite, and other RF applications by providing technical guidance, setting design standards, and solving complex engineering challenges. These engineers typically oversee teams, mentor junior engineers, and collaborate with other departments to ensure successful project delivery. Their expertise helps organizations achieve high performance and reliability in RF systems.

How does a senior principal RF engineer typically collaborate with cross-functional teams during the development of new wireless products?

A Senior Principal RF Engineer frequently works alongside hardware designers, software engineers, and product managers to ensure that wireless products meet performance specifications and regulatory requirements. Collaboration often involves participating in design reviews, troubleshooting complex RF issues, and guiding teams through the integration of RF subsystems. Effective communication and leadership skills are essential, as the role often requires translating technical RF concepts for non-specialist stakeholders and mentoring junior engineers. This team-oriented environment helps drive innovation and ensures that the end product is robust and reliable.

At Raytheon, you have the opportunity to try new things and make a bigger difference across a broader end-to-end solution, a richer technology and product set, an expanded range of disciplines. You will be on the front lines as we trailblaze new approaches, push the boundaries of innovation and chart a course to tomorrow you can be proud to have a hand in creating.

The Advanced Effector Guidance Systems team provides Electrical Systems Engineering to develop solutions for products across the Raytheon portfolio. Our team develops missile Guidance System Hardware.  Our core electrical engineering responsibilities include architecture, analysis, requirements, integration, and test.  Our core electrical engineering technologies include RF/RADAR, Navigation/IMU/GPS, Digital, and Power. We partner with several Electrical Product Team departments that provide the detailed design of our electrical products as well as missile level systems teams.

The Advanced Effector Guidance Systems Team is searching for an Electrical Systems Engineer with experience in developing RF subsystems, Radars or RF seekers. The role of the Principal RF subsystem engineer is to design, develop and maintain RF architectures. Architecture development includes requirements, analysis and modelling.  RF subsystem engineers collaborate with missile level system engineers in developing requirements for the subsystem. They perform evaluation and modeling to decompose requirements for RF sub-assemblies and component designs.

What You Will Do

  • Work environment is primarily in an office, but may include labs, field work, or a combination.

  • Evaluation of hardware designs, subsystems, and components; architecting new electronic systems; developing and documenting subsystem requirements and test plans; peer reviews of designs as a subject matter expert; presentations to peers, management, and government customers; and root-cause failure investigations.

  • Mentoring is expected.

  • Role may require supporting multiple programs.

  • Assignments may require some travel, including foreign travel.

  • Develop a network and know when to use it to get help.

  • Collaboration with both Functional and Program higher level management

  • Collaboration with Customer and Suppliers

Qualifications You Must Have

  • Typically requires a Bachelor's in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of prior relevant experience

  • Experience with electrical hardware development

  • Experience in sub-systems, systems engineering, requirement development and/or requirement validation

  • Experience in developing RF electrical subsystems

Qualifications We Prefer

  • Missile Radar and RF seeker subsystems typically contain antennas, analog RF circuit cards, digital circuit cards, and configurable logic.  The ideal candidate will have a background in detailed design and troubleshooting of one or more of these components in RF applications. Ideal candidates will also have some experience in systems engineering and architecture and have a design to grow into a guidance section architect.

  • Experience working with missiles or similar systems.

  • Knowledge of mixed signal electronics.

  • Ability to manage cross-functional teams.

  • Ability to drive suppliers in meeting commitments.

  • Knowledge of DoD/DoW hardware development process (knowledge of design gates).

  • Knowledge and/or experience with Model Based Systems Engineering (MBSE).
