As of Aug 15, 2026, the average yearly pay for freelance rf filter design engineer in the United States is $117,680.00, according to ZipRecruiter salary data. Most workers in this role earn between $97,500.00 and $139,000.00 per year, depending on experience, location, and employer.

What does a freelance RF filter design engineer do?

A Freelance RF Filter Design Engineer specializes in designing, developing, and testing radio frequency (RF) filters that are used to allow or block specific frequency signals in electronic devices. They work independently or on contract to provide custom solutions for clients in telecommunications, aerospace, defense, and consumer electronics. Their role typically involves circuit simulation, schematic design, prototyping, and ensuring that filters meet technical requirements for performance and reliability. Freelance engineers often offer flexibility and specialized expertise for companies needing short-term or project-based RF filter development.

What is the difference between Freelance Rf Filter Design Engineer vs RF Circuit Design Engineer?

AspectFreelance Rf Filter Design EngineerRF Circuit Design Engineer
CredentialsTypically requires RF engineering certifications, specialized training in filter designRequires RF engineering degrees, certifications, and circuit design expertise
Work EnvironmentIndependent, project-based, often remoteIn-house or consulting, team-based environments
Industry UsageUsed in telecommunications, aerospace, defense for custom filter solutionsApplied across wireless, consumer electronics, and communication systems

While both roles involve RF engineering, a Freelance Rf Filter Design Engineer specializes in designing RF filters independently for various clients, focusing on custom solutions. An RF Circuit Design Engineer has a broader scope, working on various RF circuits within a company or project team. The freelance role offers flexibility and specialization, whereas the RF Circuit Design Engineer typically works within structured teams on diverse RF projects.

How do freelance RF filter design engineers typically collaborate with clients and other engineers during a project?

Freelance RF Filter Design Engineers often work remotely, using digital communication tools to collaborate with clients, project managers, and sometimes other engineering specialists. They typically participate in virtual meetings to discuss specifications, share design progress, and address technical challenges. Providing regular updates and detailed documentation is essential, as is being responsive to feedback and design revisions throughout the project. Clear communication and efficient use of simulation and CAD tools help ensure the final filter meets performance and integration requirements.

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

To thrive as a Freelance RF Filter Design Engineer, you need a solid background in electrical engineering, strong understanding of RF principles, and experience in filter design, typically supported by a relevant engineering degree. Proficiency with simulation tools like ADS, HFSS, or CST, and familiarity with PCB design software are commonly required, along with knowledge of relevant industry standards. Excellent problem-solving, communication, and time management skills help set candidates apart, especially when working with remote clients or multidisciplinary teams. These capabilities ensure precise, efficient filter designs that meet client specifications and project deadlines in a competitive market.

Job description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
BAW FILTER DESIGN ENGINEER (STARLINK/AKOUSTIS)
Akoustis is now operating as a wholly owned subsidiary of SpaceX, providing industry leading RF filters using patented XBAW technology to help drive the mission of making human life multi-planetary and connecting the world through Starlink. We design, build, launch, and operate the world's largest constellation of satellites, enabling us to operate a global internet network unbounded by traditional ground infrastructure limitations. The root of SpaceX's success so far lies in our mission to keep all engineering and production in-house, which enables a tight feedback loop, nimble decision-making, and speedy deliverables. With millions of daily users worldwide already online, Starlink is truly a game-changer and levels the playing field for those who were previously unconnected.
XBAW technology utilizes MEMS-based thin film transfer process, enabling a broad range of piezoelectric material synthesis and compositions tailored for specific application needs with enhanced material properties and an optimized resonator performance, including a superior figure of merit from coupling and Q factor.
RESPONSIBILITIES:
  • Responsible for designing and developing BAW filters from concept to production, including specification definition, simulation, characterization, front-end and back-end testing, architecture design, and performance optimization
  • Perform advanced EM simulations using tools such as HFSS, ADS, or COMSOL to model BAW filter performance, optimize designs, and ensure manufacturability
  • Design RF modules integrating BAW filters, including layout, packaging, and integration with other RF components such as amplifiers, switches, and antennas
  • Optimize filter performance for key metrics such as insertion loss, return loss, bandwidth, and out-of-band rejection, while meeting size and cost constraints
  • Work closely with process engineers, layout designers, and system architects to ensure seamless integration of BAW filters into larger RF systems
  • Develop test plans, perform RF measurements, and validate filter performance using tools like network analyzers and spectrum analyzers
  • Create detailed design reports, simulation results, and technical documentation to support design reviews and production handoff
  • Stay updated on industry trends and advancements in BAW technology, contributing to the development of next-generation RF solutions

BASIC QUALIFICATIONS:
  • Bachelor's degree in electrical engineering or other engineering discipline
  • 1+ years of experience with RF, antenna, or communication systems (internship and extracurricular experience is applicable)
  • Experience in EM simulation tools (e.g. HFSS, CST, ADS, or COMSOL)
  • Experience with radio test and measurement equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, and network analyzers

PREFERRED QUALIFICATIONS:
  • Master's degree or PhD in electrical engineering with emphasis in RF/antenna engineering
  • Experience with 5G, Wi-Fi, or IoT RF front-end module design
  • Familiarity with MEMS fabrication processes for BAW filters
  • Knowledge of mixed-signal design and co-simulation with analog/digital circuits
  • Experience with scripting languages (e.g., Python, MATLAB) for automation of simulation and testing workflows

ADDITIONAL REQUIREMENTS:
  • Must be willing to work extended hours and weekends as needed to meet critical milestones

ITAR REQUIREMENTS:
  • To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
