Principal Software Engineer for Integration & Test

About the Team:

The Real-time Architectures, Integration, and Demonstration (RAID) Group focuses on transition of algorithms from concept to real-time software, providing open architecture expertise, and facilitating integration of capabilities for experimentation, test, and deployment.

The Role:

As a Principal Software Engineer, you will lead technical teams developing real-time software for advanced RF sensor systems. You will architect software solutions compliant with open architecture standards, lead the transition of algorithms from concept to real-time implementation, and mentor junior engineers.

What you will do:

• Lead technical teams in architecting, developing, and deploying real-time RF sensor software derived from diverse sources

• Transition advanced algorithms from MATLAB/Python prototypes to optimized production C/C++ implementations within open architecture frameworks

• Optimize software performance for real-time, resource-constrained systems with strict latency requirements

• Architect communication infrastructure and data flows for distributed processing systems

• Lead end-to-end open system integration efforts including hardware-in-the-loop testing, ensuring seamless integration across distributed architectures, external systems, and hardware platforms

• Conduct design reviews, code reviews, and technical risk assessments and ensure software compliance with open architecture standards and frameworks

• Mentor and provide technical guidance to junior and mid-level engineers

• Write technical reports, create briefings, and present results to sponsors and senior management

• Interface with customers, program managers, and stakeholders to define technical requirements

• Lead proposal development efforts including technical approach definition, cost estimation, and white paper development

• Collaborate with algorithm developers, systems engineers, RF hardware engineers, and integration teams across programs

• Stay current with emerging technologies and best practices in real-time software development

• Support approximately 20% travel for customer meetings, integration events, and field demonstrations

Who you are:

• Active clearance at the Secret level with ability to obtain and maintain a Top Secret security clearance, for which U.S. citizenship is needed by the US government

• BS, MS, or PhD in Computer Science, Computer Engineering, Electrical Engineering or a related field with a minimum of 5-10+ years of relevant work experience depending on degree (BS +10 years, MS +8 years, PhD +5 years)

• Experience in two or more of the following areas:

• Professional software development, C++ for high-performance real-time applications, real-time software for signal processing or sensing applications, Architecture development, leading complex software development efforts, open systems architecture integration, hardware / software integration, proposal leadership

Even Better:

• Active Top Secret Security Clearance (TS/SCI preferred)

• Strong testing mindset with experience in unit testing, integration testing, and continuous testing frameworks

• Experience with:

• Multithreaded programming, distributed systems, performance optimization

• Real-time constraints, latency budgets, and deterministic behavior

• RF signal processing concepts

• GPU programming and optimization (CUDA, OpenCL)

• Containerization, CI/CD pipelines, and DevOps practices

• Linux and embedded systems development

• MATLAB and/or Python for algorithm prototyping
