Senior RF Engineer

If you are unable to complete this application due to a disability, contact this employer to ask for an accommodation or an alternative application process.

We are pleased to announce the opening for an RF Engineer, who will join our Advanced Sensing Area in-person in our Huntsville, Alabama office and become part of our rapidly growing technology company operating in missile defense, cybersecurity, test range modernization, biotechnology, and space control market spaces. You will be part of a team known for turning research concepts into working prototypes quickly, staying hands-on from design through test.

The RF Engineer is responsible for the engineering, analysis, assessment, test, integration, and modernization of radio frequency (RF), radar, sensor, and related electromagnetic systems that support missile defense, space control, test range modernization, operational assessment, and advanced defense technology missions. In this role, you will lead complex radar, RF, sensor assessment, hardware, test, or analysis efforts.

• You will design RF systems and subsystems for research and development prototypes, developing and allocating requirements, performing analysis and trade studies, and selecting architectures and components to meet program needs.
• You will independently own RF engineering tasks and work packages, making sound judgments about assumptions, performance drivers, and technical risk, and validating your results before others rely on them.
• You will take designs from concept to working prototype hardware, specifying and sourcing components, coordinating with vendors and procurement, and assembling and integrating RF hardware in the lab, including fabricating cables and connectorized assemblies and performing bench-level rework.
• You will plan and execute test and evaluation of prototype hardware, writing test plans and procedures, taking measurements, troubleshooting to root cause, and documenting assumptions, methods, results, and limitations for internal stakeholders and customers.
• You will work across the full RF bench to bring up and evaluate new hardware, using instrumentation such as vector network analyzers, spectrum and vector signal analyzers, signal and arbitrary waveform generators, oscilloscopes, RF power meters, noise figure analyzers, and software defined radios, and you will calibrate and verify your setups so that the data you produce holds up.
• You will characterize prototype hardware and system performance through measurements including S-parameters, insertion and return loss, VSWR, gain and compression, noise figure, phase noise, intermodulation and spurious response, and modulation quality.
• You will develop software in C++ and Python in support of your hardware, including instrument control and test automation, signal processing, and data analysis and visualization tools that make measurements repeatable.
• You will work with RF signals and waveforms, including generating and analyzing I/Q waveform files, characterizing signal environments, and evaluating end-to-end system performance.
• You will support a variety of research and development efforts across nSI’s markets, moving between programs as priorities shift, and will coordinate with multidisciplinary teammates across systems, software, mechanical, and cyber disciplines as well as with government customers, subcontractors, and equipment manufacturers.
• You will contribute to proposals, technical white papers, and new research ideas, and will help scope new RF work as opportunities arise.

• You must have a Bachelor’s degree in Electrical Engineering or a related STEM field.
• You will need 5 years of full-time professional experience in RF engineering or a closely related field.
• You will need hands-on experience with RF laboratory test equipment and measurement techniques.
• You will need proficiency in Python, MATLAB, or a similar engineering computing environment for analysis and automation.
• You must possess or be able to obtain an active Secret clearance.
• You must be a U.S. citizen to be eligible for this position.

Lacking any one of these disqualifies you from this job.
