Job Description

This opening is for a large and dynamic program developing electronic attack and mission capabilities for the Compass Call EW aircraft fleet in Hudson, NH, a cornerstone of our Countermeasure & Electromagnetic Attack Solutions (CEMA) group, as we expand our capabilities to support growing global demand for advanced electronic warfare systems. As a Senior Software Engineer, you'll take on a critical role in designing, developing, and integrating mission software that disrupts adversary radar and communication networks, with a focus on both domestic and international applications.

Your expertise will directly strengthen national defense and give our warfighters, as well as our allied partners, the edge in contested environments. You'll work with modern C++ and C# in secure Linux environments, contributing to the development of real-time mission software and advanced processing frameworks. In this senior role, you'll apply your technical depth to complex challenges, collaborate across disciplines, and drive innovation in the electromagnetic battlespace.
What You'll Do

  • Contribute across the full software lifecycle - from requirements definition through system integration and verification.
  • Develop and optimize real-time software frameworks for both domestic and international applications.
  • Apply Agile and DevSecOps practices, including CI/CD pipelines, automated testing, and code reviews.
  • Work collaboratively with multidisciplinary teams including systems, hardware, and test engineers to solve cross-disciplinary technical challenges and ensure seamless integration.
  • Ensure compliance with software development standards and security protocols.
  • Mentor and support early-career engineers, helping to build technical skills and reinforce best practices.
