GNC Engineer, Attitude Control Systems

About the role

The GNC Engineer, Attitude Control Systems will play a crucial part in the development of spacecraft pointing, maneuvering, and momentum management systems. Leveraging Pulsar's advanced PNT satellite infrastructure, this role involves designing, simulating, implementing, and testing control algorithms under real-world mission conditions.

Responsibilities

• Develop and maintain 6DOF attitude simulations for ACS design and verification.
• Design, tune, and validate PID, LQR, and optimal control algorithms.
• Develop actuator allocation logic for reaction wheels, torque rods, thrusters, or other effectors.
• Implement momentum management and desaturation algorithms.
• Support model-based development, integration, and test workflows.
• Run SIL/HIL test campaigns and analyze performance across nominal and off-nominal cases.
• Develop unit, regression, and simulation-based tests.

Requirements

• Experience with 6DOF attitude dynamics simulations.
• Hands-on experience with PID, LQR, or optimal control design.
• Experience with actuator allocation, momentum management, or desaturation logic.
• Experience with model-based software development processes.
• Experience with SIL/HIL simulation and test environments.
• Experience developing unit or regression tests.
• Strong programming skills in Python, C++, and MATLAB.
• Proficiency with Git and Linux environments.

Qualifications

• BS or MS in Aerospace Engineering, Electrical Engineering, Control Systems, Applied Physics, or a related technical field.
• Experience developing ACS algorithms for spacecraft, satellites, UAVs, or autonomous systems.
• Familiarity with reaction wheels, magnetic torque rods, thrusters, star trackers, IMUs, magnetometers, or sun sensors.
• Experience with flight software integration, embedded deployment, or real-time systems.
• Experience with Monte Carlo analysis, robustness testing, or fault-case validation.
• Familiarity with autocoding workflows from MATLAB/Simulink or similar tools.
