Northrop Grumman Defense Systems is seeking a self-motivated, proactive Principal Software Engineer to join the medium-caliber Bushmaster gun controller product line. The role offers a high-exposure, fast-paced environment where hands-on technical challenges, problem-solving, and cross-department collaboration are the norm. The engineer will be responsible for delivering high-quality, innovative software that meets system requirements, coding standards, and technical design specifications while supporting the full product lifecycle-from requirements through integration, test, and verification.

Key Responsibilities
* Design, develop, and implement software functionality - Create and deliver software that meets system and customer requirements while respecting industry best practices, cost targets, and technical constraints.

* Develop and integrate embedded SW for microcontroller-based hardware - Apply solid software engineering skills to design, code, and test firmware while performing hands-on hardware activities such as bench-level debugging, hardware-software integration, and peripheral configuration on microcontrollers and associated circuitry. This responsibility ensures that the candidate can bridge software development with real-world hardware implementation to deliver reliable, high-performance embedded solutions.

* Develop software requirements - Elicit, define, and document functional and non-functional requirements; lead the creation and validation of requirement specifications and ensure clear traceability to system specifications, design artifacts, and test deliverables.

* Perform requirements decomposition, verification, validation, and troubleshooting - Break down high-level requirements into implementable units, verify and validate each element throughout the development cycle, and resolve issues through systematic analysis.

* Implement software solutions - Write clean, maintainable, and testable code in C, C++, Java, LabVIEW, Python, or other required languages; integrate modules, adhere to coding standards and security best practices, and modify code as needed for functional testing.

* Plan and execute software testing
- * Update and calibrate test equipment and fixtures.

* Develop comprehensive test cases and automated test suites.

* Conduct functional, integration, regression, and hardware-in-the-loop testing.

* Perform hands-on debugging, root-cause analysis, and corrective actions

* Oversee contractor testing activities when applicable to ensure compliance with test plans and quality criteria.

* Verify and validate requirements - Execute systematic V&V activities, confirm that the implemented software satisfies all stipulated requirements, and produce traceability matrices, verification reports, and compliance documentation.

* Produce comprehensive documentation - Author design-review packages (PDR/CDR), verification & validation (V&V) reports, interface control documents (ICDs), user manuals, and detailed test procedures that support the full product lifecycle.

* Develop and apply control algorithms - Design closed-loop control solutions (e.g., PID), state-machine patterns, and motor-control techniques for safety-critical embedded systems.

* Collaborate with cross-functional teams - Work closely with product-development teammates, mechanical and electrical engineers, and other specialists to ensure seamless integration across the hardware-software development process.

* Maintain configuration management - Use Git (or equivalent) for source-code control, manage software builds, and ensure version-controlled artifacts are available to the team. Basic Qualifications
* Bachelor of Science degree in Computer Science, Computer Engineering, Electrical Engineering (or related field) plus 5 years of embedded software engineering experience; or a Master's degree plus 3 years of experience.

* Proven experience in embedded systems software development, integration, and testing. Other

Basic Qualifications:

* Ensure that teammates succeed in delivering what's most important for the team.

* Have a willingness to learn…
