  • 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
Required Qualifications
  • Bachelor's or Master's degree in Electrical Engineering or related field

  • 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
