About The Position

As a GNC Engineer, you will be joining the team responsible for the design, development, and implementation of algorithms that allow our vehicles to navigate complex environments and execute precise maneuvers. You will bridge the gap between theoretical flight physics and real-world software implementation, ensuring stability and performance across all flight regimes.

Requirements

• Education: Master’s or PhD in Aerospace, Mechanical, or Electrical Engineering (with a focus on Controls).
• Control Theory Mastery: Deep understanding of MIMO/SISO systems, frequency domain analysis, and Lyapunov stability.
• Programming: Proficiency in Python or MATLAB/Simulink for modeling and C++ for flight software implementation.
• Mathematics: Strong foundation in linear algebra, coordinate transformations (Quaternions, Euler angles), and orbital mechanics or aerodynamics.

Nice To Haves

• Experience with simulation tools (JSBSim, Gazebo, etc)
• Hands on experience with open-source autopilot
• Experience with radar and rocket systems
• Understanding of rocket GNC, aerodynamics, flight dynamics and controls
• Understanding of computer vision, perception, filtering, and estimation

Responsibilities

• Flight Dynamics Modeling: Develop high-fidelity 6-DOF (Degrees of Freedom) simulations to predict vehicle behavior.
• Control Law Design: Design, tune, and analyze flight control laws using both Classical (PID, Root Locus, Bode) and Modern (LQR/LQG, H-infinity, State-Space) techniques.
• Navigation & Estimation: Implement sensor fusion algorithms (e.g., Extended Kalman Filters) to provide accurate state estimates from IMU, GPS, and star tracker data.
• Guidance Algorithms: Develop trajectory generation and path-planning logic for autonomous mission phases.
• Performance Analysis: Conduct Monte Carlo simulations and Linear Stability Analysis (Gain/Phase margins) to ensure system robustness.
• Hardware-in-the-Loop (HITL): Support the integration of GNC software with flight hardware and sensors.
