Temporary Matlab Simulink Jobs (NOW HIRING)

Job Title: GNC Engineer - Controls

Job Description

This role focuses on designing, analyzing, and implementing guidance, navigation, and control (GNC) algorithms for aerospace vehicles. You will develop advanced control laws, build high-fidelity dynamic models, and translate GNC designs into robust, flight-ready software. The position requires close collaboration with multidisciplinary teams to ensure that GNC systems perform reliably under both nominal and off-nominal conditions throughout the mission lifecycle.

Responsibilities

• Design, analyze, and implement guidance, navigation, and control (GNC) algorithms for aerospace vehicles.
• Develop and refine control laws using classical and modern control techniques, including PID, LQR, MPC, adaptive control, and other linear and nonlinear methods.
• Evaluate, select, and integrate spacecraft control effectors such as thrusters, reaction wheels, and control moment gyroscopes (CMGs).
• Perform six-degree-of-freedom (6-DOF) modeling, simulation, and performance analysis to evaluate system behavior under nominal and off-nominal conditions.
• Build high-fidelity dynamic models of vehicles, sensors, actuators, and environmental disturbances, including flexible effects and their mitigation.
• Conduct Monte Carlo analyses, sensitivity studies, and stability assessments to validate robustness, reliability, and control system margins.
• Use tools such as MATLAB/Simulink, Python, C, C++, or similar environments to develop, run, and refine simulations.
• Translate GNC algorithms into flight-ready software, ensuring numerical stability, computational efficiency, and real-time performance.
• Collaborate with embedded software teams to integrate, test, and verify GNC functionality on hardware-in-the-loop (HIL) systems.
• Support the development of requirements, interface definitions, and verification plans for flight software related to GNC functions.
• Plan and execute verification and validation activities, including unit tests, software-in-the-loop (SIL) testing, hardware-in-the-loop (HIL) testing, and integrated system tests.
• Analyze flight test or mission data to assess GNC performance, diagnose issues, and identify opportunities for improvement.
• Contribute technical expertise in flight control systems and control law development across the broader station project team.

Essential Skills

• Proven experience in guidance, navigation, and control (GNC) engineering for aerospace applications.
• Strong experience in control law development, including both linear and nonlinear control techniques.
• Hands-on experience with flight control systems and flight control software implementation.
• Practical experience working with actuators such as reaction wheels, control moment gyroscopes (CMGs), and thrusters.
• Proficiency in C++ for implementing control algorithms and flight software.
• Proficiency with MATLAB and related toolchains for control design, simulation, and analysis.
• Experience conducting Monte Carlo simulations for robustness and sensitivity analysis.
• Ability to perform 6-DOF modeling and simulation of aerospace vehicles and their subsystems.
• Experience modeling flexible effects and implementing mitigation strategies within control systems.
• Strong understanding of aerospace engineering principles, particularly in GNC and control law design.
• Ability to ensure numerical stability, computational efficiency, and real-time performance in embedded GNC implementations.

Additional Skills & Qualifications

• Experience in aerospace engineering or a closely related discipline.
• Experience with guidance, navigation, and control (GNC) algorithm development for spacecraft or aerospace vehicles.
• Familiarity with Python, C, or similar programming languages for simulation and analysis.
• Experience collaborating with embedded software teams and working within integrated development environments.
• Exposure to hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing for flight software verification.
• Understanding of requirements development, interface definition, and verification planning for flight systems.
• Experience analyzing flight test or mission data to validate control performance and refine algorithms.
