Principle Stress Engineer Location Stevenage: Hybrid, 3 days per week onsite (Relocation considered) Salary: Circa £58,000 DOE plus Benefits Security: British Citizen or a Dual UK national with British citizenship. I’m supporting a client in Stevenage who is expanding their Mechanical Analysis capability and looking for a Principal Stress Engineer to take a lead role in the structural development of a next-generation weapon platform. The work centres on solving demanding structural problems, shaping the design approach, and setting the standard for analysis quality across a major programme. More about the role as Principle Stress Engineer… * You’ll be working at the point where mechanical design, systems architecture and performance requirements meet. * You will be guiding structural decisions from early concept through detailed development and test. * Expect a mix of classical methods, advanced CAE work, loads development and the engineering judgement needed to interpret real-world behaviour in a complex system. * Composite analysis experience is useful but not mandatory. About the business you’ll work within as Principle Stress Engineer… * The environment suits someone who wants technical depth, accountability, and the space to apply rigorous thinking. * You’ll plan and deliver work packages, challenge assumptions within multi-disciplinary teams, and present clear technical arguments to senior stakeholders. * You’ll also mentor less experienced analysts and help refine the group’s methods and tools—this isn’t a maintenance role; it’s development, improvement and influence. What’s on offer as Principle Stress Engineer * The position is based in Stevenage with hybrid working (typically three days on-site due to classification requirements). * Salary is around £58k depending on experience * additional benefits including bonus, enhanced pension, flexi leave, overtime options, and relocation support where needed. The security stuff BPSS and SC security clearance are required, with eligibility limited to UK nationals or dual UK citizens. If you want a role where structural analysis genuinely drives system capability and where your engineering decisions have direct consequences for performance, survivability and safety, this is worth a conversation
