## Description

Join our Flight Software team and help define how a launch vehicle behaves throughout all phases of flight. This role sits at the intersection of Guidance, Navigation & Control, flight dynamics, mission analysis, simulation and flight software, turning engineering insight into robust C++ and Python implementations that can be tested, verified and flown.

Your Role in Our Space Mission

 * Develop, improve and verify GNC algorithms for launch vehicle applications.
 * Contribute to guidance strategy, navigation solutions and vehicle control techniques.
 * Support trajectory design, mission analysis and flight performance assessment.
 * Develop and maintain high-fidelity simulation environments for design, development and verification.
 * Model vehicle dynamics, environmental effects, sensors, actuators and subsystem interactions.
 * Implement and integrate GNC algorithms within production flight software.
 * Create analysis, testing and automation tools using C++, Python and MATLAB.
 * Investigate anomalies and unexpected behaviour in simulation, testing and flight operations, driving issues to root cause.
