Designs and performs manual and automated tests of radio frequency (RF) digital communications systems and their components. Troubleshoots any problems that arise during testing. Uses RF lab equipment (signal generators, signal analyzers, power meters, oscilloscopes, etc.) to aid testing and debugging. Knowledgeable in Ettus USRP architecture and related software (UHD, RFNoC, Python or C/C++), as well as continuous integration/continuous deployment (CI/CD) tools and pipelines is very helpful. Develops RF and digital processing blocks on Ettus USRP radios (X310s and X410s) to aid RF systems and testing. Develops CI/CD tools (GitLab CI and Artifactory) and pipelines for automated testing. Participates in design tasks including requirements analysis and interface definition. Analyzes digital signals and system performance in MATLAB. Optimizes software when necessary. Ensures performance requirements can reliably be met.
RESPONSIBILITIES:
Testbed design and integration with COTS and/or prototype components
Design and implement RF communications and digital processing blocks on USRPs
Define and execute both manual and automated system tests. Tests will be both over-the-wire and over-the-air
Perform RF communications data collection
Perform data analysis and organize RF plus network performance data
Report internally via verbal and written methods
REQUIRED SKILLS:
Experience testing RF systems: communications radios, antennas, COTS components, networking, etc.
Experience working on a Linux platform
Experience with programming and scripting languages: MATLAB, Python, C/C++, and Bash
Experience with Ettus USRPs or similar software defined radios
Bachelor s Degree in STEM field
Microsoft Office
PREFERRED SKILLS:
Understanding of RF communication systems and digital signal processing
Experience with Ettus X310s or X410s and related GNU and UHD software
Experience programming Ettus USRP s Xilinx FPGAs
Experience with CI/CD pipelines and related tools: GitLab CI, Artifactory, etc.
Experience with version control software such as Git
Experience using RF lab test equipment: signal generators, signal analyzers, power meters, oscilloscopes, etc.
