Looking for RF integration and test engineer with background in designing, integrating, and executing both lab and over-the-air tests of prototype tactical communications systems.

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
