Job Description:
We are seeking an experienced RF Designer to lead the design, development, and validation of high-frequency circuits and systems for demanding applications including aerospace, defense, industrial, and medical products. This role requires deep expertise in RF/microwave design, PCB materials, and system integration, along with the ability to work in a customer-facing environment.
Key Responsibilities:
Design and develop RF and microwave circuits including amplifiers, filters, mixers, oscillators, and antennas
Perform schematic capture, simulation, and layout of high-frequency PCBsSelect and apply advanced RF materials (e.g., Rogers laminates such as RO4350B, RO4003C, RT/duroid series)
Conduct RF simulation using tools such as:
- Keysight ADSAnsys HFSSCadence AWR Microwave Office
- Optimize impedance matching, signal integrity, and EMI/EMC performance
- Develop RF test plans and perform lab validation using VNAs, spectrum analyzers, and signal generators
- Collaborate with PCB layout, mechanical, and manufacturing teams to ensure design for manufacturability (DFM/DFA)
- Interface directly with customers to define requirements, present designs, and support technical reviews
- Support prototype builds, troubleshooting, and production ramp-upQualificationsRequired Qualifications
- Bachelor's or Master's degree in Electrical Engineering or related field 8+ years of experience in RF/microwave design
- Strong understanding of transmission lines, impedance matching, S-parameters, and EM theory
- Hands-on experience with RF test equipment (VNA, spectrum analyzer, power meters)
- Experience designing multilayer RF PCBs and working with controlled impedance structures
- Familiarity with high-frequency PCB materials and stack-up design
Preferred Qualifications:- Experience with mmWave or high-frequency (>10 GHz) designs
- Knowledge of hermetic and high-reliability packaging techniques
- Experience with LTCC, hybrid circuits, or module-level RF design
- Familiarity with military and aerospace standards (MIL-STD, IPC Class 3)
- Experience designing for harsh environments (temperature, vibration, radiation)
Key Skills:- RF circuit simulation and modeling
- Signal integrity and power integrity analysisPCB layout guidance for RF performance
- Debugging and root cause analysis
- Strong communication and customer interaction skills
Due to ITAR and / or CUI compliance, this position requires candidates to be a U.S. Citizen.
