What is a Principal RF Engineer job?

A Principal RF Engineer is a senior-level engineering professional responsible for designing, developing, and optimizing radio frequency (RF) systems and components. They lead complex RF projects, analyze system performance, and ensure compliance with regulatory standards. This role typically involves mentoring junior engineers, collaborating with cross-functional teams, and solving technical challenges related to wireless communication, antenna design, or signal propagation. Principal RF Engineers work in industries such as telecommunications, aerospace, and defense to enhance wireless networks and communication systems.

What are the key skills and qualifications needed to thrive in the Principal Rf Engineer position, and why are they important?

To excel as a Principal RF Engineer, extensive knowledge of radio frequency (RF) design, system integration, and a degree in electrical engineering or related field are essential. Experience with RF simulation tools (such as HFSS, ADS, or CST), familiarity with spectrum analyzers, and relevant certifications like the IEEE Wireless Communication certification are commonly expected. Exceptional problem-solving abilities, leadership, and clear communication skills help drive projects and support multidisciplinary collaboration. These attributes ensure successful RF system development, effective project leadership, and seamless integration of complex technologies in demanding environments.

What are the typical daily responsibilities of a Principal RF Engineer?

As a Principal RF Engineer, you can expect to spend your days designing and optimizing RF circuits and systems, conducting simulations and testing prototypes, and troubleshooting performance issues. You’ll frequently collaborate with cross-functional teams, including hardware designers, software engineers, and project managers, to ensure seamless integration of RF components within larger systems. Additionally, you may mentor junior engineers, review technical documentation, and contribute to strategy discussions for new product initiatives. This dynamic role combines technical expertise with leadership and teamwork, offering both hands-on and strategic responsibilities.

At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

We are actively seeking passionate, collaborative, energetic, and forward-thinking individual to join our team as a Principal RF Engineer I. The ideal candidate has extensive experience in board-level and system-level RF electronics design. If you enjoy working in a startup environment and are passionate about developing leading-edge phased arrays for satellites, spacecraft, and aerospace systems, we would like to hear from you.
 
In this position, you will be responsible for RF circuits, modules, and systems through all phases of the development process. The ideal candidate will be proficient in board-level schematic design and PCB layout of RF circuits, system-level communications concepts such as link budgets and modulation schemes, and end-to-end RF product development. The work will include many aspects of phased array communication systems, including RF front ends, frequency converters and synthesizers, filters, beamformers, power dividers, and phased array antennas.
 
As a principal hardware team member, you will be responsible for RF system and hardware designs from initial concept through requirements definition, architecture definition, part selection, detailed design, analysis, manufacturing, testing, qualification, and in-orbit support of Cesium's products. Hardware design tasks will include block diagrams, detailed schematics, PCB layout and routing, simulations, and test design. Principal Engineers also serve as technical and professional mentors in their field and may be given the opportunity to lead company programs.
 
The successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
Successful candidates will require:
  • Bachelor of Science (BS)) degree in Electrical Engineering (EE) from an accredited university or institution.  Master of Science (MS) desired.
  • Minimum of 9 years of industry experience in design and analysis of RF electronics and systems.
  • Expert-level proficiency in professional simulation tools such as CST and ADS, as well as EDA tools such Altium.
  • Extensive hands-on experience with lab instruments such as vector network analyzers, spectrum analyzers, signal generators, and oscilloscopes.
  • Excellent written and verbal communication skills.
Preferred experience includes:
  • Python or other programming languages.
  • Aerospace electronics design, development, and qualification.
  • Worst-case circuit analysis, failure method and criticality analyses, and reliability analysis.
  • Antenna design
  • EMI/EMC design and mitigation techniques.
$142,000 - $189,500 a year
