Senior Systems Engineer (Defence Infrastructure)

Join AtkinsRéalis as a Senior Systems Engineer in our Advanced Engineering Delivery & Consultancy practice. You will apply your systems engineering experience to major defence and secure infrastructure projects, working in collaborative, multi-disciplinary teams. You will lead technical work packages, mentor developing engineers, and engage confidently with senior client stakeholders. The role will primarily be delivered from the client's site, with regular on-site attendance required throughout the working week.

Are you ready to apply your systems engineering expertise to programmes that genuinely matter?

Experience in defence, nuclear, secure infrastructure, Critical National Infrastructure or RIBA-based project delivery would be advantageous — but we are equally interested in people who can bring transferable systems engineering capability from other complex sectors

Responsibilities

• Appliquer l'ingénierie des systèmes à des programmes d'infrastructure de défense majeurs, en intégrant les exigences, la conception, l'assurance et l'acceptation.
• Diriger l'ingénierie des exigences, en veillant à ce que les besoins soient capturés, tracés, vérifiés et gérés.
• Identifier et gérer les interfaces entre les systèmes, les disciplines, les installations, les entrepreneurs et les parties prenantes.
• Lead systems engineering within complex defence, infrastructure, nuclear, energy, transport or regulated programmes
• Collaborate with multi-disciplinary teams to deliver integrated engineering solutions
• Support design reviews, technical assurance, governance and acceptance processes
• Communicate complex technical issues effectively to clients, delivery teams and senior stakeholders
• Use systems and digital engineering tools such as DOORS, Cameo, Sparx EA and Jama
• Manage requirements, interfaces, verification, validation and acceptance activities

Requirements

• Hold, or be working towards, professional registration such as CEng, ASEP or CSEP
• Apply systems engineering standards and frameworks, including ISO 15288, ISO 29148 and INCOSE guidance
• You’ll bring practical systems engineering experience and the confidence to apply it in complex, multi-disciplinary project environments. You do not need to have spent your whole career in infrastructure — what matters is your ability to bring structure, integration and technical clarity to complex delivery challenges
