About the role

New-graduate RF Hardware Test Engineer to verify RF modules, assemblies, and interfaces for airborne and ground systems. Focus on test execution, RF measurements, data analysis, troubleshooting, and qualification support within a multidisciplinary team in a defense-tech environment.

Responsibilities

  • 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.
  • Collaborate with RF, electrical, mechanical, systems, software, manufacturing, and supplier teams.
  • Perform other duties as assigned.

Qualifications

  • Bachelor's or master's degree in Electrical Engineering, Applied Physics, or a related technical field, completed or expected within 12 months of the anticipated start date.
  • coursework/experience in RF or microwave engineering, communications, electromagnetics, analog circuits, or electronic hardware testing.
  • Fundamental understanding of S-parameters, impedance, transmission lines, gain and loss, noise, power, spectral content, and frequency response.
  • Hands-on laboratory experience from coursework, research, internship, student organizations, or personal project.
  • Basic programming and data-analysis skills in Python, MATLAB, or similar.
  • Ability to follow test procedures, document setups and results accurately, recognize uncertainty, and seek guidance as needed.
  • Clear written and verbal communication skills and ability to work in a multidisciplinary team.
  • Ability to work on-site in a laboratory and hardware-development environment.
