What you'd do

  • Execute documented RF test plans and procedures with mentorship, record test configurations, and produce clear, traceable results.
  • Characterize RF modules and assemblies for S-parameters, gain and loss, output power, compression, harmonics and spurious emissions, isolation, rejection, noise figure, and receiver sensitivity as applicable.
  • Set up and operate vector network analyzers, spectrum analyzers, signal generators, power meters, oscilloscopes, noise-figure equipment, programmable power supplies, and related laboratory instruments.
  • Calibrate measurement setups and characterize cables, adapters, attenuators, fixtures, and other sources of measurement error.
  • Develop simple test fixtures, harnesses, interface adapters, and monitoring circuits; perform basic soldering and hardware rework when appropriate.
  • Automate instrument control, data collection, analysis, and plotting using Python, MATLAB, or comparable tools.
  • Compare measured performance with requirements, identify unexpected behavior, and summarize conclusions in engineering reports and reviews.
  • Troubleshoot test anomalies with senior engineers and learn to distinguish device behavior from setup, calibration, software, or environmental artifacts.
  • Support EMI/EMC pre-compliance and MIL-STD-461 qualification testing, environmental testing, hardware integration, and ground or flight test activities as needed.
  • Maintain safe, organized laboratory practices and follow equipment calibration, configuration-control, and data-management processes.
