and DSP applications.



If you thrive in a fast-paced, technical environment and are passionate

about developing software that powers next-generation RF and DSP

systems, we want to hear from you!



Job Description:



As a C++ Software Engineer, you will design, implement, and optimize

high-performance software for advanced DSP and RF systems. You will work

closely with signal processing, hardware, and systems engineering teams

to develop and deliver mission-critical applications. This role requires

a strong foundation in C++ programming, DSP algorithms, and RF signal

processing.



Responsibilities:



Software Development & Optimization



- Design, develop, and maintain C++ software for real-time DSP and RF

applications.



- Implement and optimize signal processing algorithms (e.g.,

filtering, modulation, demodulation, FFT).



- Write multi-threaded, high-performance code for real-time and

embedded environments.



- Collaborate with hardware engineers to integrate software with RF

receivers/transmitters.



System Design & Testing



- Design and implement software architectures for RF and DSP systems.



- Develop and maintain automated testing frameworks to ensure code

reliability and performance.



- Conduct performance profiling and optimization for low-latency and

high-throughput applications.



Collaboration & Documentation



- Work closely with signal processing, RF, and systems teams to define

software requirements.



- Document code, algorithms, and system architecture for internal and

external use.



- Participate in code reviews, design reviews, and system integration

testing.



Requirements:



Education:



- Bachelor’s or Master’s degree in Computer Science, Electrical

Engineering, or a related field.



Experience:



- 3-7 years of experience developing C++ software, preferably for DSP

or RF applications.



- Strong background in digital signal processing, including algorithm

development and implementation.



- Experience working with real-time and/or embedded systems.



Technical Skills:



- Proficient in C++ (11/14/17) with experience in modern software

design patterns.



- Strong understanding of DSP concepts (e.g., FFT, filtering,

modulation, sampling theory).



- Experience with Linux-based software development.



- Knowledge of multi-threading, low-level programming, and performance

optimization.



- Familiarity with hardware interfaces (e.g., PCIe, Ethernet, USB) and

integrating with RF systems.



Tools & Frameworks:



- Development Tools: GCC, CMake, GDB, and other Linux-based

development environments.



- Signal Processing Tools: MATLAB, GNU Radio, or equivalent for

algorithm prototyping.



- Version Control: Git (preferred) or other source control systems.



Preferred Qualifications:



- Experience with Software-Defined Radios (SDR) or RF communications

systems.



- Familiarity with FPGAs, VHDL, or Verilog for hardware acceleration.



- Knowledge of machine learning applications for signal processing.



- Experience working with DoD or government projects (e.g., SIGINT,

ELINT).



- Active security clearance (or the ability to obtain one).



Soft Skills & Competencies:



- Strong problem-solving abilities and attention to detail.



- Ability to communicate complex technical concepts clearly and

effectively.



- Collaborative mindset with the ability to work independently and as

part of a cross-functional team.
