Guidance, Navigation, & Control Engineer (GNC)

Description:Job Summary: The GNC Engineer will support the design, integration, testing, and flight validation of advanced autonomous systems, including UAVs, seekers, precision-guided munitions, and aerospace platforms. They will be responsible for autopilot configuration and tuning, aerodynamic performance analysis, SIL/HIL setup, and Monte Carlo-based performance assessment, working closely with systems, software, hardware, optics, and test teams. This role spans the full lifecycle from conceptual design through flight test and fielding.Requirements:Guidance, Navigation, and Control Development: Design, implement, and tune GNC algorithms for autonomous and semi-autonomous vehicles, including: UAVs (fixed-wing, rotary-wing, VTOL) Precision-guided munitions and seekers Small, high-dynamics aerospace vehicles Configure, integrate, and tune autopilots (commercial, open-architecture, or custom flight controllers) across multiple vehicle classes. Develop and analyze control laws, guidance strategies, and navigation filters to meet performance, stability, and robustness requirements. Autopilot Integration & Tuning:Configure flight control architectures including: Inner-loop attitude and rate control Outer-loop velocity, position, and guidance control Tune controllers for performance across the operational envelope, accounting for: Aerodynamic uncertainties Actuator limits and saturation Sensor noise, bias, and latency Support integration of IMUs, GPS/GNSS-denied navigation, seekers, and auxiliary sensors. Experience deploying solutions on both fixed and rotary wing platforms is preferred. Modeling, Simulation, and Analysis: Develop and maintain 6-DOF vehicle models incorporating: Aerodynamics Mass properties Actuator and sensor models Perform aerodynamic performance analysis and sensitivity studies. Build and execute Monte Carlo simulations to assess dispersion, miss distance, robustness, and system margins. Support trade studies and design decisions using quantitative simulation results. SIL/ HIL/ Test Infrastructure: Design, implement, and maintain Software-In-the-Loop (SIL) and Hardware-In-the-Loop (HIL) test environments. Integrate real flight software, avionics, and sensors into simulation frameworks. Diagnose discrepancies between simulation, HIL, and flight results. Support bench testing, captive-carry tests, and flight tests. Flight Test & Data Analysis: Support ground and flight test planning, execution, and post-test analysis. Analyze flight data to assess: Stability and control performanceGuidance behavior and tracking accuracy Navigation performance and sensor fusion Identify anomalies, root causes, and corrective actions. Iterate designs based on test results and operational feedback. Documentation & Standards: Produce clear, disciplined engineering documentation, including: GNC requirements and design descriptions Simulation and test plans Test reports and performance summaries Work within DoD and aerospace engineering best practices, including configuration control and traceability. Support technical reviews (SRR, PDR, CDR, TRR, FRR). Knowledge, Skills, and QualificationsStrong fundamentals in: Rigid-body dynamics Flight mechanics Control theory (classical and modern) State estimation and sensor fusion Hands-on experience with: Autopilot setup, configuration, and tuning UAV or small-vehicle flight control systems C code development, object-oriented design MATLAB/Simulink, Python, or equivalent modeling tools Ability to analyze complex data sets and communicate results clearlyWe are an equal employment opportunity and affirmative action employer.
