Systems Engineer - Hardware-in-the-Loop About the Role We are looking for analytical engineers to join our Hardware-in-the-Loop (HWIL) team, delivering world-class, closed-loop performance testing for advanced defence systems. This is a unique opportunity to work at the forefront of technology, helping ensure the highest levels of operational confidence through cutting-edge testing and simulation. The HWIL team conducts dynamic firing simulations using real hardware to support product development, performance validation, and de-risking trials. You will work in a state-of-the-art facility equipped with advanced target generation and flight motion systems, recreating near real-world scenarios and integrating model data in real time to simulate in-flight performance, target detection, and homing. Because HWIL projects cover such a wide range of activities, the work is varied and challenging-no two weeks will be the same. Your focus will be on integrating, maintaining, and running complex simulations that provide critical data and insights for product development. Key Responsibilities Understand system sub-components involved in dynamic testing Assess and manage interactions between systems and bespoke test equipment Collaborate closely with multidisciplinary engineering teams Develop and run real-time simulations using performance models Conduct experiments with integrated hardware and software systems Analyse performance data and prepare clear reports on findings What We're Looking For We are seeking engineers with a broad technical background. Experience in some of the following areas will be an advantage (you do not need to have all of them): System integration and interface debugging Structured problem-solving techniques Software or simulation design Testing of sensors or other sub-systems System performance analysis What We Offer A varied and challenging role in a cutting-edge engineering environment Hybrid and flexible working options Enhanced parental leave and family support Excellent on-site facilities including subsidised meals and free parking A collaborative and innovative workplace with opportunities for professional development
