Our employees are not only part of history, they're making history.Northrop Grumman Space Systems—Missile Defense Integration offers an excellent opportunity for a Sr Principal Software Engineer (Algorithm) – TRK (26-332) to join our team of skilled and diverse professionals. Based in Huntsville, AL, this role is essential to supporting the U.S. President, the Secretary of Defense, and combatant commanders at the strategic, regional, and operational levels.This position does not provide relocation assistance and requires on-site work with no remote options.Position Overview:The Command and Control, Battle Management, and Communications (C2BMC) program is a key component of the Missile Defense System. It is a vital operational system that enables the U.S. President, the Secretary of Defense, and combatant commanders at strategic, regional, and operational levels to plan ballistic missile defense operations systematically, collectively monitor the battle, and dynamically control networked sensors and weapon systems to achieve global and regional mission goals.C2BMC supports layered missile defense capabilities that enable an optimized response to threats across all ranges and flight phases. It serves as a force multiplier by networking, integrating, and synchronizing autonomous sensor and weapon systems and operations, both globally and regionally, to improve performance. C2BMC is also essential for all ground and flight tests that verify and demonstrate the current and future capabilities of missile defense systems.As a member of the Regional Applications (RA) Agile Release Train (ART) of the Missile Defense National Team for C2BMC (C2BMC NT), the SLD Algorithm Engineer Lead – TRK will be a key contributor to the design, development, integration, and leadership of Java-based mathematical algorithms in support of the C2BMC System Discrimination (SLD) mission area.Essential Functions:Lead the design and development of complex, Java-based mathematical algorithms for SLD, with an emphasis on tracking and discrimination to support C2BMC operational capabilitiesDevelop and maintain algorithm-design artifacts, including architecture descriptions, design documentation, and technical presentationsImplement MATLAB and/or Java-based software changes and prototypes, and support the transition of prototype algorithms to real-time tactical Java implementationsSupport and/or lead design and code reviews to ensure high-quality, maintainable, and testable software solutionsPerform software testing, data analysis, and troubleshooting; identify root causes of system behavior issues and recommend effective solutionsSupport integration, testing, and verification of algorithm design and performance across lab, ground test, and flight test environmentsPresent developed designs, analyses, and results to internal and external stakeholders, including program leadership and customer representativesCollaborate closely with Systems Engineering, Integration and Test, Deployment, and Warfighter Support teams to ensure mission success and alignment with operational requirementsActively participate in agile planning and execution using established C2BMC processes, including work decomposition, backlog refinement, and leadership in sprint ceremoniesMentor junior engineers and contribute to the continuous improvement of processes, tools, and technical approaches within RA ARTBasic Qualifications: Please list your current security clearance and IAT or relevant certifications on your resume, if applicable.
