Radio Frequency Microwave Engineer

Judge Consulting Group; Seattle (WA); On-site; USD 110,000 - 160,000; Full time

Job summary

Judge Consulting Group in Seattle is seeking an RF/microwave engineer to lead the architecture and design of phased array systems. You will own RF design from architecture through validation, collaborating with RFIC, antenna, EE, and ME teams to shape the product roadmap.

As an early hire, you will help shape our design methodology, develop top-level models, run system simulations, and drive design iterations based on real measurement data.

Qualifications

• Bachelor's degree in Electrical Engineering or related field.
• 3–5 years of RF/mmwave design experience.
• Proficiency with industry-standard design and simulation tools (ADS, CST, HFSS, AWR or similar).
• Proficiency with mmWave lab equipment and measurement techniques at high frequencies.
• Solid RF fundamentals: matching, noise, linearity, and S-parameters.

Responsibilities

• Develop top level models, link budgets and architectures for communications and radar systems.
• Run system-level simulations covering linearity, noise, gain/phase control accuracy, and power budgets.
• Design RF/microwave circuits, MMICs, passive/printed components, substrates, chip break-outs, matching networks and packages.
• Design RF modules and SIPs consisting of RFICs passives and other RF components.
• Collect and analyze characterization data and drive design iterations of fabricated parts.
• Collaborate with antenna, digital, and DSP teams to meet full-system requirements.
• Coordinate with mechanical/thermal teams to manage heat dissipation and packaging constraints, and work with PCB layout teams for grounding and signal integrity.

Job description

We're looking for a motivated and technically excellent RF/microwave engineer to help design our phased array and system solutions. As one of our early hires, you won't just execute against a spec handed down to you—you'll contribute to the architecture and design methodology behind our products and help shape how the team works as it grows.

You'll own RF design from architecture through the different design phases, working shoulder-to-shoulder with RFIC, antenna, EE and ME teams. The decisions you make will ripple through every product we build.

Responsibilities

• Develop top level models, link budgets and architectures for communications and radar systems
• Run system-level simulations covering linearity, noise, gain/phase control accuracy, and power and develop line up budgets
• Design RF/microwave circuits, MMICs, passive/printed components, substrates, chip break-outs, matching networks and packages.
• Design RF modules and SIPs consisting of RFICs passives and other RF components
• Make this real by collecting and analyzing characterization data, and provide solutions for design iterations of fabricated parts
• Collaborate with antenna, digital, and DSP teams to ensure system performance meets full-system requirements
• Collaborate closely with mechanical and thermal teams to manage heat dissipation and packaging constraints, and work with PCB layout teams to ensure robust grounding and signal integrity for high-frequency designs.

Minimum Qualifications

• Bachelor's degree in Electrical Engineering or a related field
• 3-5 years of relevant experience in RF/mmwave design
• Proficiency with industry-standard design and simulation tools (e.g., ADS, CST, HFSS, AWR or similar)
• Proficiency with mmWave lab equipment and measurement techniques, including calibration at high frequencies
• Solid foundation in RF fundamentals: matching, noise, linearity, and S-parameters

Preferred Qualifications

• Masters degree or PhD with a focus on RF/microwave circuits/systems or electromagnetic theory
• Background in communication and radar systems
• RF/microwave design in Ku, Ka, V, E, and/or W-band frequency range
• Experience with design of linear and non-linear circuits such as power amplifiers, low noise amplifiers, mixers, filters and PLLs
• Experience in Matlab, Python, C++ or equivalent tools for modeling and analyzing RF systems
• Schematic and layout using Altium Designer or other PCB design tools
• Knowledge of digital communication systems, spread spectrum, single and multi-carrier techniques and modulation types such as QPSK, APSK and QAM
• Familiarity with mm-wave design and silicon technologies (SiGe BiCMOS, CMOS, GaAs/GaN)
