What are the key skills and qualifications needed to thrive as a Freelance RF Filter Design Engineer, and why are they important?

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.

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 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.

Job description

We are looking for an RF Engineer who can design, simulate, and validate Sub-GHz and Wi-Fi/BLE radio systems and perform RF PCB layout. This is an end-to-end role spanning architecture, simulation, PCB implementation, prototyping, lab validation, and certification (FCC/CE only - no carrier certification).
We build RF/RFID anti-theft technology solutions for apparel labeling, item tagging, and tag readers for retail and industrial environments. You will own the RF front end, antenna integration, controlled-impedance layout, and bring-up of complex PCBs used in our wireless products. You will work closely with electrical, mechanical, firmware, manufacturing, and test teams to deliver robust, manufacturable RF designs.
JOB DUTIES
RF System Design
  • Design Sub-GHz ISM (e.g., 850 - 950 MHz) and 2.4 GHz Wi-Fi/BLE RF front ends.
  • Create link budgets, block diagrams, matching networks, power budgets, and specifications.
  • Component selection for PAs, LNAs, filters, switches, mixers, couplers, and RF shields.
  • Antenna evaluation and integration (chip, PCB trace, external, diversity).

RF PCB Design
  • Full ownership of RF zones on multilayer PCBs.
  • Define stack-up, controlled impedance routing, grounding, isolation, stitching, and keep-outs.
  • Work directly in Siemens PADS for schematics + layout (not just oversight).
  • Lead DFM/DFT reviews and coordinate with fabrication/assembly partners.

Simulation & Analysis
  • Use Dassault CST, Siemens HyperLynx, Keysight ADS, or similar tools for S-parameters, matching, stability, and radiation effects.
  • Perform EM analysis for antenna tuning and layout-dependent parasitics.
  • Support coexistence analysis between Sub-GHz and 2.4 GHz radios.

Lab Bring-Up & Validation
  • Use VNA, spectrum analyzer, signal generator, power meter, and oscilloscopes.
  • Conduct S11/S21 measurements, EVM checks, output power, sensitivity, desense analysis, and coexistence testing.
  • Tune antenna/matching networks and document all tuning steps.
  • Support environmental testing (temperature, vibration, humidity) as relevant to RF performance.

Compliance & Certification
  • Execute FCC/CE/UKCA and EMC/EMI requirements (no cellular carrier certification).
  • Work with external labs for testing; generate test reports and resolve findings/NCs.

Cross-Functional Support
  • Collaborate with FW for RF calibration/test flows.
  • Work with manufacturing on golden units, calibration constants, and test limit development.
  • Support field failure analysis and yield improvements during NPI.

• EDUCATION
  • B.S. or M.S. in EE or related field.
  • IPC CID certification (plus).

EXPERIENCE
  • 5-8+ years owning RF designs from concept → production.

KNOWLEDGE, SKILLS, & ABILITIES (KSA's):
  • Deep experience with Sub-GHz ISM radios and Wi-Fi/BLE coexistence.
  • Strong proficiency in RF layout, isolation, stack-up, and parasitic control.
  • Experience taking products through FCC/CE certification with minimal NCs.
  • Experience using Dassault CST, Siemens HyperLynx, Keysight ADS, Cadence AWR, Matlab, or EM simulation (antenna/matching).
  • High-volume manufacturing experience (DFM for HDI, low-loss laminates, shields).
  • Ability to mentor junior engineers and lead design reviews.
  • Familiarity with OTA, SAR, and EMC testing environments.
  • Work with Qualcomm/NXP/Nordic/TI/Silicon Labs chipsets.

Job Type: Full-Time - Exempt
Pay: $120,000.00-$140,000.00
Benefits:
  • 401 (k)
  • 401 (k) Matching
