Guidance, Navigation Control Engineer IV, Navigation Specialist - S

About the Role

We are seeking an experienced Guidance, Navigation, and Control (GNC) Engineer, Navigation Technical Specialist who will perform technical execution scope associated with navigational system design, algorithm development, software integration, sensor system modeling & analysis, performance analysis, hardware integrated testing, and weapons system verification within the Theater Strike Weapon Systems (TSWS) and Strategic Missile Defense (SMD) portfolios. The role is anchored by the Conventional Prompt Strike (CPS) program and involves multiple product lifecycle phases.

• Work on advanced missile design, integration, testing, and analysis within a hypersonic weapon system program.
• Leverage past experience in weapon system and missile system/subsystem development and analysis to shape current and future program execution.
• Collaborate with program managers, systems and software engineering leaders to deliver component(s)/subsystem(s), designs, and analysis to programs.
• Provide programmatic direction to engineering staff and team(s), collaborate on execution, analysis, design, and peer reviews.
• Apply proficiency in C++ and MATLAB to develop, verify, validate, and perform analysis; review analysis artifacts of others, assess data products, and deliver technical summary briefings.
• Communicate technical results effectively and work collaboratively across teams, working groups, review boards, and technical execution teams.
• Support Agile execution of programs and projects through proposals, planning/backlog development, product ownership, and staffing coordination.
• Develop and review data packages, analysis, and presentations for working groups and review boards.
• Coordinate internal efforts and external elements (partner, subcontractor, peer prime) to develop, verify, and validate navigational sensors and algorithms to achieve weapon system performance.
• Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements across simulation, hardware testing, and full system test execution.
• Support program reviews and technical interchange meetings with internal leadership and/or external customers.

• B.S. or M.S. in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or related field.
• Demonstrated experience working on defense, aerospace, and/or space navigation programs.
• Fundamentals of inertial navigation systems (INS) and/or GNSS (multi-constellation, RTK, SBAS).
• Familiarity with navigation performance metrics (accuracy, availability, continuity, integrity).
• Understanding of Position, Navigation, and Timing (PNT) concepts, error budgeting, and integrity monitoring.
• Proficiency in C/C++, MATLAB/Simulink, and/or Python for algorithm development and data analysis.
• Knowledge of software methods or standards including safety critical items and/or version control systems (Git, Gitlab, Artifact repositories).
• Ability to develop and maintain navigation error budgets, covariance analysis, and/or perform statistical analyses.
• Proficiency with high‑fidelity simulation tools.

• Professional experience of 9+ years focused on GNC within a weapon system product lifecycle.
• Experience in INS & GNSS systems, including INS error modeling, GNSS signal structures, multi‑constellation processing, platform transfer alignment, and integration algorithms (e.g., Kalman filters, particle filters).
• Experience in Advanced PNT Concepts such as precise orbit determination, time transfer, sensor fusion (INS, GNSS, ADS), integrity monitoring, differential GNSS, and emerging technologies.
• Demonstrated navigation performance metric efforts; ability to define, compute, and validate metrics such as accuracy, integrity, continuity, availability, and reliability.
• Experience defining technical requirements, reviewing subcontractor proposals, managing interface control documents with traceability, and validating deliverables.
• Familiarity with cyber‑resilient navigation concepts, anti‑spoofing/anti‑jamming techniques, and secure PNT architectures.
• Designing, configuring, and executing HWIL test rigs for navigation software validation on…
