## About the Role

The ability to obtain and maintain a U.S. government issued security clearance is required., The ideal candidate enjoys working in a multi-disciplinary role and is comfortable adapting to and identifying new technologies as needed. This candidate would have experience in implementing and maintaining high-performance software, as well as a solid understanding of computer architectures, networking, device drivers, and analog and digital interfaces. A strong background in signal processing and control-system algorithm implementation and optimization is also desirable, but not required at start., * Typically requires a Bachelor's Degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of prior experience, or an Advanced Degree in STEM and a minimum of 5 years of prior experience.

 * The ability to obtain and maintain a U.S. government issued security clearance is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.
 * Experience that includes at least two of the following areas: Embedded C/C++ Software; High-Performance Computer Systems; Embedded Real-Time Sensors and Control Applications; and/or Advanced Software Architecture Design and Implementation.
 * Experience using embedded Real Time Operating Systems (RTOS) (e.g., Linux, Green Hills, Integrity, Wind River VxWorks, etc.).
 * Experience developing complex systems involving the integration of hardware, firmware, and software.

Qualifications We Prefer:

 * Proficiency using C/C++.
 * Familiarity with digital signal processing algorithms and software.
 * Knowledge of linear algebra concepts.
 * Experience using the VSIPL high-performance vector library or another vector processing library.
 * Experience implementing and optimizing algorithms from high level specifications.
 * Experience with real-time performance optimization.

Special consideration will be given to a candidate who either possesses an active Secret-level (or higher) security clearance, or who has previously held such a clearance.
