Northrop Grumman Defense Systems is seeking Principal / Sr. Principal GN&C Engineer to support activities including flight simulator development, GN&C algorithm development and implementation, and "test as you fly" with rigorous model and requirements verification and validation. This position will be in Roy, Utah supporting Flight Systems Futures.
The selected engineer in this role will develop and mature guidance and control (G&C) algorithms, guidance laws for trajectory shaping, and high-fidelity 6-DOF flight simulations for complex aerospace systems. This includes designing guidance laws to meet mission-specific trajectory and end-game performance objectives, and tuning control laws using classical and modern control techniques (PID, gain scheduling, optimal and robust control) while integrating these algorithms into simulation and flight software environments.
The engineer will enhance existing G&C analysis tools, perform covariance and circular-error-probable (CEP) accuracy assessments, and contribute to emerging mission capabilities across advanced programs.
The ideal candidate is a collaborative team player and strong independent contributor who demonstrates ownership of tasks, initiative, and sound technical judgment. They show advanced problem-solving skills and excellent written and verbal communication, coupled with strong interpersonal and organizational capabilities, a proactive mindset, and a meticulous, detail-oriented approach to their work.
Primary Responsibilities Include, But Are Not Limited To- Collaborate with a team of GN&C engineers in an Agile environment to meet critical milestones
- Develop, verify, and validate guidance and control algorithms, including guidance laws for trajectory shaping, and 6-DOF flight simulations in a multi-disciplinary team environment
- Perform trajectory assessment, flight analyses, covariance analysis, and CEP/accuracy evaluations
- Enhance and maintain G&C analysis tools to support new mission requirements and performance tuning
- Apply trajectory optimization and nonlinear control techniques to improve missile trajectory performance.
- Participate in engineering review boards, technical interchange meetings, and critical milestone reviews
- Work with the GN&C Flight Software Team to automatically generate code from high-level specifications or models, ensuring consistency and reducing manual errors
- Model key subsystems such as IMUs, control actuators, and propulsion / thrust-vector control for use in G&C design and simulation
- Use C++ and MATLAB with object-oriented design principles to implement and analyze G&C software
- Collaborate closely with GN&C flight…
