GNC Engineer

Job description

About company :

Astrophel Aerospace is on a mission to redefine space exploration with our cutting-edge reusable launch vehicle technology. Our vision is to make space more accessible and sustainable while driving down costs for industries and researchers alike. Backed by our recently secured pre-seed funding, we are now assembling a talented core team to bring this vision to life and push the boundaries of aerospace innovation.

Role Overview :

As a GNC Engineer, you will play a critical role in the design, development, simulation, and real-world implementation of guidance, navigation, and control systems for our launch vehicles. From crafting algorithms and carrying out high-fidelity simulations to making them a reality through hardware integration and testing, you'll help ensure our vehicles meet stringent performance, stability, and safety requirements — from lift-off to orbital insertion

Key Responsibilities :

● Develop and implement guidance, navigation, and control algorithms for launch vehicles.

● Design and simulate closed-loop GNC systems using MATLAB/ Simulink and other analysis tools.

● Perform 6-DOF trajectory simulations, stability analysis, and Monte Carlo assessments.

● Collaborate with avionics, propulsion, and flight software teams for integrated system development.

● Analyze sensor and actuator performance, including IMUs, GPS, reaction control systems, and thrust vector control.

● Carry out software-in-the-loop (SIL) testing.

● Support hardware-in-the-loop (HIL) testing.

● Participate in pre-flight mission planning, flight readiness reviews, and post-flight performance analysis.

● Contribute to the definition of mission requirements and system architecture for new vehicle designs.

Required Qualifications :

● Bachelor's or Master's degree in Aerospace Engineering, Control Systems, or a related field.

● Strong foundation in classical and modern control theory, navigation filters, and guidance law design.

● Proficiency in MATLAB/Simulink and Python for system modeling and analysis.

● Experience with 6-DOF simulation and dynamic system modeling.

● Familiarity with embedded real-time systems, flight software, and hardware integration.

● Understanding of sensors (IMU, GPS) and actuator dynamics relevant to spaceflight.

● Excellent problem-solving skills, with attention to detail and strong analytical capability.

Preferred Qualifications :

● Experience in launch vehicle or spacecraft GNC system design and flight test support.

● Knowledge of Kalman filtering, state estimation, and sensor fusion techniques.

● Experience with C/C++ and embedded software development for flight-critical applications.

● Familiarity with flight dynamics, aerodynamics, and propulsion systems.

● Hands-on experience with hardware-in-the-loop and system-level validation testing.

Why Join Us ?

● Be part of an agile and innovative team shaping the future of space launch.

● Work & Learn on real missions with hands-on impact on design, development, and flight operations.

● Competitive salary, benefits, and growth opportunities.

"If you're a passionate, tech-driven GNC Engineer who gets excited about crafting guidance laws, tuning control loops, and bringing trajectories to life — both in simulation and on the launch pad — we'd love to have you on board."
