What is a principal RF engineer?

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 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.

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.

Job description

Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.

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 looking to add a Principal RF Test Engineer I to our team. If you enjoy working in a startup environment and are passionate about developing critical test systems for leading-edge satellite, spacecraft, and aerospace communication systems, we would like to hear from you.
 
In this position, you are responsible for the design, analysis, and implementation of engineering test plans and procedures. The ideal candidate possesses a strong combination of hardware and software knowledge with proficiencies in RF measurements, test equipment (VSAs, VSGs, VNAs, etc.), test architectures, and automation. The successful candidate will work closely with multi-disciplinary teams to address company-wide hardware test needs. Experience with phased array testing is preferred.
 
Core day-to-day responsibilities include collaborating with design and test engineering teams to develop test requirements, mapping requirements to reusable test architectures and procedures, implementing test plans and procedures, and logging and presenting results to key stakeholders. Additional responsibilities include lab and equipment management and guiding key equipment purchase decisions.
 
Principal-level test engineers are distinguished by an ability to architect RF test systems, to draw insightful conclusions from test results, and to participate in "design for test" planning and review from the early stages of RF product development. Test engineers are core members of the Cesium technical team.
 
The successful candidate will 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.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
  • Bachelor of Science (BS) or higher degree in Electrical Engineering or Computer Engineering from an accredited university or institution.
  • Minimum of 9 years of industry or university research experience in design, analysis, and implementation of RF test systems. 
  • High proficiency with RF measurements (Linearity, NSD, EVM, etc.).
  • Test architecture design and development including scripting, test executives, hardware, and measurement abstraction layers.
  • Proficient in performing conducted RF measurements including S-parameters, AM/PM, compression, noise figure, harmonics/spurious emission, phase noise, switching speed, bit error rate, adjacent channel power, and group delay.
  • Hands-on experience with lab instruments such as digital oscilloscopes, multimeters, electronic loads, source measurement units, RF signal generators, spectrum analyzers, network analyzers, and vector signal analyzers.
  • Excellent written and verbal communication skills.
PREFERRED EXPERIENCE
  • Familiarity or hands-on experience with phased array over the air range testing, including phase/amplitude calibration, EIRP, G/T, axial ratio, scan loss and pattern cuts.
  • Programming or scripting experience (Python, MATLAB, C/C++, etc.)
  • Understanding of RF and mixed-signal hardware (e.g. amplifiers, filters, ADCs/DACs, antennas) and its effects on test design.
