Design Engineer III

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 PCBs
• Select and apply advanced RF materials (e.g., Rogers laminates such as RO4350B, RO4003C, RT/duroid series)
• Conduct RF simulation using tools such as:
  • Keysight ADS
  • Ansys HFSS
  • Cadence 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-up

Qualifications

Required 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 analysis
• PCB 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.
