Join our partner as a Principal Simulation and Modelling Engineer, where you'll lead cutting-edge development, integration, and validation of dynamic numerical models that shape mission-critical systems. If you're ready to influence the future of system simulation within a dynamic, security-cleared environment, this is the perfect opportunity for you. Key Skills and Qualifications: * Proven expertise in MATLAB and Simulink for system modelling and simulation. * Strong understanding of dynamic systems, numerical modelling, and system engineering processes. * Experience with model-based design methodologies and the software development lifecycle. * Knowledge of coding standards, peer review practices, and configuration management. * Hands-on experience with automated C/C++ code generation from Simulink. * Proficiency with version control tools such as Git or EWM. * Excellent problem-solving, analytical, and communication skills. * Experience working with external partners and cross-disciplinary teams. Preferred Education and Experience: * A solid background in engineering, systems engineering, or related technical disciplines. * Significant hands-on experience (ideally 5 years) in simulation and modelling roles within a defence, aerospace, or similar high-tech environment. Other Requirements: * British Citizenship with the ability to obtain SC security clearance post-offer. * Willingness to work on-site full-time due to workload requirements. * Flexibility for occasional travel as needed. * Commitment to quality standards, documentation, and configuration management
