With a global team of more than 13,000 top professionals, we partner with the best in industry to expand the bounds of innovation in the defence and scientific arenas. In the UK, we are leading the way in avionics and communication systems. Given the nature of our work and who we are, we value trust, honesty, alignment and transparency.

General Dynamics in St Leonards-on-Sea currently provide avionic mission computing systems for a wide range of military fast jets, helicopters, and UAV’s. Recent success has resulted in General Dynamics developing the next generation of Advanced High Performance, Safety Critical Mission Computer Systems to meet the needs of latest platforms in development by several aircraft manufacturers. These Mission Computing Systems provide the functionality that integrates aircraft systems, sensor systems and stores management systems with the information and control systems required by the aircrew to meet the demanding operational needs of these aircraft.

This is a key role within the Core Technologies team at GD-MS UK, taking ownership of the development activities of the common Digital IO cards, including those with integrated FPGA chips, to be used across all the company's project delivery to various defence customers. As Senior Systems Engineer, you will drive the technical excellence and innovation of these critical platform components, ensuring they meet the demanding requirements of our defence sector clients. You will implement Model-Based Systems Engineering (MBSE) methodologies on new products. You will oversee the implementation of model-based approaches on existing Digital IO card product lines whilst managing parallel documentation during the transition period.

Key Responsibilities:

• Establish and build comprehensive SysMLv2 requirements models for new Digital IO card developments from inception, ensuring consistency and traceability across all system elements - Conduct comprehensive systems-level analysis and technical evaluations to identify optimisation opportunities and resolve complex engineering challenges such as FPGA integration, utilising both traditional and model-based approaches
• Own the Verification & Validation (V&V) cycle, ensuring testing is comprehensively planned and delivered to achieve full sign-off of product design, with complete traceability to requirements models maintained throughout the development lifecycle
• Collaborate with mechanical, hardware, firmware, and software engineering teams to ensure seamless integration and system compatibility across all project deliverables, promoting adoption of MBSE practices across disciplines
• Lead technical design reviews and provide expert guidance to junior engineers on both traditional systems engineering and model-based systems engineering methodologies, fostering knowledge sharing and continuous improvement - Develop and maintain detailed technical documentation, including design specifications, architecture diagrams, and SysMLv2 models, ensuring alignment between document-based and model-based representations
• Ensure all Digital IO card designs comply with relevant industry standards, regulatory requirements, and organisational quality standards for defence applications - Analyse emerging technologies and industry trends to inform future Digital IO card development strategies and systems engineering practices
