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.\nGeneral 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.\n Join our security engineering team and help deliver future combat-air capability as part of the GCAP programme. You will work on complex, safety-critical mission-computing systems, embedding security into the product architecture and engineering lifecycle.\nWorking alongside specialists across systems, software, hardware, safety and certification, you will help ensure that security risks are identified, understood and addressed through robust engineering solutions. This is an opportunity to influence the design of advanced airborne technology while contributing to a strategically important UK defence programme.\nThis is a product and systems security engineering role, focused on embedding security into complex, safety-critical airborne mission systems.\nIn this role you will:\nOwn and lead the product-security architecture for complex airborne mission systems\nDefine the security strategy, requirements and secure-by-design approach across the programme lifecycle\nLead threat modelling, vulnerability analysis, security risk assessment and accreditation activities\nProvide technical authority and informed security advice across systems, software and hardware engineering\nMake and communicate proportionate security decisions, balancing operational capability, technical risk and programme constraints\nLead engagement with customers, programme partners and relevant assurance stakeholders\nReview security evidence and ensure that proposed designs and mitigations support the required assurance outcomes\nCoach and provide technical guidance to security and multidisciplinary engineering teams\nDrive the adoption of consistent product-security methods, tools and good practice across the programme\n Essential experience\nSignificant experience developing or leading product-security or systems-security architecture for complex engineered products\nKnowledge of Secure by Design principles and relevant product and systems security standards, ideally gained within defence, aerospace or another safety-critical engineering environment\nStrong experience defining security requirements and secure-by-design approaches at system or product level\nExperience leading threat modelling, security risk assessment and vulnerability-analysis activities\nExperience providing technical leadership and making security architecture decisions across multidisciplinary engineering teams\nKnowledge of cryptographic principles and their application within secure products or systems\nExperience engaging with customers, partners and assurance stakeholders on complex security matters\nAbility to translate security threats and risks into practical engineering requirements and design decisions\nDegree-level qualification in engineering, computer science, cyber security or a related discipline, or equivalent relevant experience\nDesirable experience\nExperience in aerospace, defence, avionics, mission systems, embedded systems or other safety-critical products\nExperience acting as a product-security technical authority, security architect or engineering lead\nKnowledge of accreditation, certification and security-assurance approaches within regulated environments\nExperience coaching or technically leading security engineers\nFamiliarity with digital engineering, model-based systems engineering or requirements-management tools\nExperience working with or familiarity with AI/ML models is preferred\n This role has a salary of between £59,200 and £80,000 plus our flexible benefits package.\nWe are open to this role being spent with time working from home and in the office (hybrid - typically 3 days working in office) on a weekly basis or fully in our offices.\nWe pride ourselves in being a great place to work with a shared sense of purpose, offering impressive benefits:\nA compressed nine-day fortnight and compressed hours - which means every other Friday off. \nA personalized career development plan, alongside regular progress reviews - supporting and valuing your progression within the Company. \nA flexible working environment where your contributions are recognized and rewarded with flexible benefits \nWe believe in maintaining a diverse workplace - inclusive of beliefs, cultural background, job experiences, thoughts and ideas.
