This role is positioned at the critical intersection of early-phase design and strategic growth, where you will transform high-level concepts into viable technical scopes that ensure long-term success in major national and international programs. Rather than following a pre-defined path, you will help create the roadmap. You will operate in a high-visibility capacity, providing essential engineering expertise into the Future Business areas (such as Deep Strike, Hypersonics, Tactical Strike, Air Domain, Air Defence, Battlefield and Future Combat Air Systems) to ensure that new opportunities are technically grounded and competitively positioned. Why this role is compelling: This position offers the opportunity to lead the technical narrative during the most creative phase of the product lifecycle. You will have the autonomy to explore new functionality and apply cutting-edge Systems Engineering techniques to solve complex problems before they are fully defined. You will act as a key technical integrator, bridging the gap between ambitious customer needs and deliverable engineering plans What you will be doing: Your focus will be on the logical and functional evolution of the system. You will lead activities across the system design spectrum, with examples of your focus areas including: Concept Development & Funnelling: Leading the conceptualization process, managing the evaluation of various options, and driving the rigorous "funnelling" process toward technical down-selection. Functional Architecture & Performance: Defining the functional behaviour and system-level performance requirements, ensuring the logical architecture supports the overarching mission goals. Missile System Capability: Defining the specific capabilities of the missile system to ensure it meets operational needs, focusing on the missile system design. Technical Delivery & Planning: Owning the technical milestones for task groups and collaborating with Subject Matter Experts (SMEs) to translate high-level goals into detailed, deliverable plans of work. Requirements Orchestration: Leading the early capture of customer needs and translating them into structured specifications (such as CPS, SRS, and TRS) using industry-standard approaches & tools. Strategic Collaboration: Engaging with stakeholders at all levels to align technical strategy with business objectives If you are a Systems Engineering professional who enjoys the challenge of early-phase design and possesses the drive to steer the technical direction of future missile systems, this is an exceptional opportunity to make a lasting impact What we're looking for from you: Extensive experience in Systems Engineering, especially desirable if within early-phase conceptual work. Experience with developing and applying requirements, ideally including familiarity with approaches and tools to capture and translate customer needs into specifications. Ability to engage at a technical level across multiple disciplines (Physical Architecture, Aerodynamics, Propulsion, Guidance Control & Navigation, etc) Comfortable with occasional engaging into Sales and Business Development & Strategy to understand wider objectives and direction Comfortable working with ambiguity and in uncertainty Delivery-focused with positive and enthusiastic outlook Highly Desirable: experience in technical project management and competitive bidding. Highly Desirable: Team and Technical Leadership skills Desirable: Proven ability to develop Functional Architectures and system-level performance requirements. Desirable: Awareness of Model-Based Systems Engineering (MBSE). Our company: Peace is not a given, Freedom is not a given, Sovereignty is not a given MBDA is a leading defence organisation.
