What is a freelance RF design engineer?

Freelance RF Design Engineers are independent professionals who specialize in designing, testing, and optimizing radio frequency (RF) circuits and systems for various applications, such as telecommunications, wireless networks, and broadcasting. Unlike salaried employees, they work on a contract or project basis for different clients, providing their expertise on-demand. Their responsibilities often include creating schematics, selecting components, running simulations, and ensuring compliance with industry standards. Freelance RF Design Engineers need strong technical skills, up-to-date knowledge of RF technologies, and the ability to manage projects independently.

What are the key skills and qualifications needed to thrive as a freelance RF design engineer?

To thrive as a Freelance RF Design Engineer, you need a strong background in electrical engineering, RF circuit theory, and experience with wireless communication systems, often supported by a relevant degree or certification. Proficiency with RF simulation and design tools like HFSS, ADS, or CST, as well as familiarity with PCB design software, is typically required. Strong problem-solving skills, attention to detail, and effective communication are crucial soft skills for successful project delivery and client interactions. These skills and qualifications are essential to design reliable RF systems, meet client specifications, and maintain competitiveness in a project-based environment.

What are some common challenges faced by freelance RF design engineers when working with multiple clients simultaneously?

Freelance RF Design Engineers often juggle projects for several clients at once, which can present challenges such as managing different project timelines, adapting to varied technical requirements, and ensuring clear communication across diverse teams. Balancing priorities and staying organized are crucial to delivering quality work within tight deadlines. Additionally, freelancers need to quickly familiarize themselves with each client's unique tools and processes, making adaptability and proactive problem-solving essential skills for success in this role.

What is the difference between Freelance Rf Design Engineer vs Rf Design Engineer?

AspectFreelance Rf Design EngineerRf Design Engineer
CredentialsTypically holds relevant engineering degrees, certifications optionalRequires engineering degree, often with industry certifications
Work EnvironmentIndependent, project-based, remote or on-siteFull-time, employed by a company, on-site or hybrid
Employer & Industry UsageServes multiple clients across industries like telecom, aerospaceWorks for a single employer, primarily in telecommunications or electronics

Freelance Rf Design Engineers work independently on various projects, offering flexibility and diverse experience. Rf Design Engineers are typically employed full-time within companies, focusing on ongoing development. Both roles require similar technical skills and certifications, but differ mainly in employment status and work setup.

Job description

About the Team:
The STR Sensors Division specializes in the development of advanced sensor systems, with a particular focus on airborne and surface-based radar, space-based sensing, electronic warfare, and underwater acoustics. This position is within the Space Missions and Sensing (SMS) Sector of the Sensors Division. In this sector, we develop and deliver technology to advance space-based sensing, space control, and counter-sensing missions.
The Role:
The SMS Sector is seeking a RF System Engineer to lead small teams to design, develop, integrate and test novel sensing and counter sensing systems for radar, electronic warfare, and signal processing systems. This position offers significant opportunities for career growth within a fast-paced and rapidly expanding company.
What you will do:
  • Lead and work with small, multi-disciplinary teams to design, build, and test RF hardware systems. Systems are predominantly field deployable prototypes with the objective of transitioning to low-volume product systems.
  • Lead the team to quantify goals, system performance objectives, metrics, dependencies, and risks to guide your work.
  • Lead the design of RF hardware systems, tasking and guiding other engineers on your team to create drawings, select parts and components, and write specifications for components such as antennas, positioners, cables, transceiver assemblies, amplifiers, filters, etc.
  • Lead the integration and test of complete RF systems including antennas, feeds, waveguides, positioners, processing hardware, and the software providing system control, waveform processing, calibration, health and status functions and the user interface.
  • Work with mechanical engineers, software and firmware developers, system engineers, and test engineers to troubleshoot, identify, and resolve issues
  • Conduct performance trade studies and analyses of proposed hardware architectures and work with Systems Engineers and other team leads to derive, develop, and verify requirements
  • Develop component and system test plans and lead testing to verify system compliance with requirements and demonstrate/document system performance
  • Conduct over-the-air system demonstrations, identifying hardware readiness, test architecture, performance metrics, data management, operational procedures, and performance reports
  • Work with signal processing team to develop test concepts and methods
  • Conduct performance analysis through simulations and real-world testing to validate system performance
  • Review system effectiveness and identify opportunities to advance and/or mature subsystems and system capabilities
  • Prepare documentation, design specifications, test plans, and reports

Who you are:
  • This position requires the ability to obtain a security clearance, for which U.S. citizenship is required by U.S. Government
  • BS in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline
  • 10+ years experience working with RF components and subsystems, including T/R modules, rotary joints, antennas, positioners, filters, radiating structures, isolators, amplifiers, ADCs/DACs, and system signal processing, calibration and control software
  • Experience with developing requirements and verification plans for complex systems and subsystems
  • Design experience with RF system, subsystem and/or component analysis (frequency planning, link budget analysis, transceiver architectures, cascade analysis)
  • RF testing and characterization experience from component to system level
  • Experience leading teams for the integration and test of RF systems including front- end hardware, back-end hardware and software
  • Proficiency in MATLAB and/or Python and/or other higher-level languages
  • Strong mathematical, troubleshooting, written, and verbal communication skills

Even Better:
  • Active Secret, Top Secret, or TS/SCI Clearance
  • Advanced degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline
  • Experience with:
    • RF systems engineering and technologies in one or more of the following areas: sensing and electronic warfare applications including electronic attack, electronic protection, cognitive EW, radar, and advanced ESM techniques
    • EM Field Solvers (ANSYS HFSS, Sonnet)
    • Interacting with decision-makers and customers to translate mission needs into an end-to-end analytical solution
    • RF Integrated Circuits
    • RF Transceiver building blocks (power amplifiers, low-noise amplifiers, oscillators, mixers, filters)
    • High-power RF design and testing
    • Automated or semi-automated digital and RF test set development and implementation
  • Knowledge of:
    • Mechanical design
    • Software development, integration, and familiarity with C/C++ and Python
