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 provide technical leadership for the development, integration, and validation of real-time RF sensor software systems. You will work as part of a multi-disciplinary team to architect, guide, and implement software components, integrate algorithms into open architecture frameworks, and develop test infrastructure to validate system performance. This role emphasizes hands-on software development, open system integration, integrating software components across distributed architectures and with hardware platforms, and rigorous testing of real-time applications. You will establish integration and test approaches, identify and mitigate technical risks, mentor engineers, and collaborate with program leadership and government customers to ensure successful delivery of mission-critical capabilities.

What you will do:

  • Lead the technical design, development, integration, and validation of real-time sensor systems in C/C++
  • Integrate signal processing algorithms into open architecture software frameworks
  • Define, develop, and execute integration tests and system-level validation tests
  • Debug software issues in real-time, multi-threaded, and distributed systems
  • Lead the transition of algorithm specifications and MATLAB/Python prototypes into optimized production C/C++ implementations
  • Document software designs, test procedures, results, and technical reports as well as integration plans, technical briefings, and customer-facing presentations
  • Support system demonstrations and field-testing activities
  • Establish and promote best practices for software quality, configuration management, test automation, documentation, and technical risk management
  • Mentor and provide technical guidance to junior and mid-level engineers
  • Interface with government sponsors, customers, program managers, and technical stakeholders to define requirements, communicate technical status, and present results
  • Lead or substantially contribute to proposal development, including technical approach development, work-breakdown planning, technical writing, cost estimation, white papers, and customer presentations
  • Contribute to the design and implementation of user interfaces, dashboards, and visualization tools that support system observability, test execution, data analysis, and integration workflows
  • Support approximately 10% travel for integration events, field testing, and customer 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 a government requirement
  • BS, MS, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field with relevant experience depending on degree (BS + 12 years, MS + 10 years, or PhD + 5 years)
  • Ten or more years of professional software development experience, including demonstrated experience leading complex software development, integration, and test efforts
  • Expert-level proficiency in programming for high-performance, real-time applications
  • Experience with version control systems (Git)
  • Experience with Linux
  • Strong debugging and troubleshooting skills
  • Demonstrated experience developing or integrating real-time software for signal-processing, embedded, distributed, or hardware-connected systems
  • Demonstrated technical leadership and mentoring experience
  • Experience leading or substantially contributing to proposal efforts, including technical writing, technical-approach development, cost estimation, and customer presentations

Even Better:

  • Active Top Secret clearance (TS/SCI preferred)
  • Strong written, verbal, and presentation skills, including the ability to communicate technical concepts to engineers, program leadership, and government customers
  • Proficiency in Python or MATLAB
  • Experience with hands-on hardware testing and lab equipment
  • Experience in signal processing and RF sensor-system architectures
  • Experience with real-time or embedded software development
  • Knowledge of multithreaded programming and synchronization
  • Understanding of open architecture principles and standards
  • Experience developing user interfaces, dashboards, or visualization tools for system integration, test execution, operational monitoring, or data analysis
  • Awareness of usability and human-machine-interface considerations for technical, engineering, or mission-system applications
