## About the Role

The ideal candidate is a software engineer with deep RF and DSP grounding who moves comfortably
between signal theory and production code.

Required:

 - Bachelor's degree in Computer Science or a related field. Four additional years of signals software
engineering on projects with similar development processes may substitute for the degree.

 - 7+ years as a signals software engineer, or equivalent, on RF-focused projects.
 - Experience with Fourier transforms, filtering, communications theory, digital modulation, and error control coding.
 - Digital signal processing experience, such as adaptive beamforming and filtering, and demodulation.
 - Familiarity with signals analysis tools (e.g., WVT, DVT).
 - Strong C++ and Java, and an advanced understanding of Linux.
 - TS/SCI with a current Full Scope Polygraph at the time of application.

## Description

Our client is hiring a Signals Software Engineer to build and enhance signal processing software, including
detectors, demodulators, and protocol processors, for SIGINT mission systems. The engineer works independently or within a team and may lead development efforts. They contribute to system design and help diagnose problems across RF processing systems and the enterprise architecture around them., Signal processing development:

 - Design and implement signal processing algorithms, including complex ones with strict timing,
resource, or interface constraints.

 - Apply signal processing techniques to convert and process signals, and identify digital modulation
schemes.

 - Design signal processing software even when documentation is thin.
 - Build and maintain software frameworks that process data efficiently.
 - Write software in C++ and Java, and recommend other languages when a problem calls for them.

Software engineering:

 - Derive software design and performance requirements from user needs.
 - Write new code or add features to existing software; debug and correct defects.
 - Modify software to fix errors, support new hardware, or improve performance.
 - Integrate existing software into new or changed systems and environments.
 - Use scientific analysis and mathematical models to predict and measure design outcomes.
 - Analyze system flow, data usage, and work processes, and dig into problem areas.

Testing, troubleshooting, and quality:

 - Help develop and run test procedures for software components, and document the results.
 - Pinpoint the source of problems in RF processing systems and connected enterprise systems.
 - Perform quality control on products, and write and review software and system documentation.

Collaboration and leadership:

 - Work with systems and software engineers to define requirements, interfaces, project limits, and
performance needs.

 - Lead one or more development teams at the level the program's process calls for.
 - Recommend and implement improvements to documentation and development standards.
