SENIOR MARINE SYSTEMS ENGINEER BRISTOL (3 DAYS ONSITE) £65,000 - £80,000 DOE A Senior Marine Systems Engineer is required to join a specialist engineering organisation delivering high-impact work across the maritime and defence sector. This role sits at the front end of engineering-focused on concept development, capability definition, and informing strategic decisions for next-generation naval platforms. You will lead the development of platform concepts from initial capability requirements through to high-level designs, supporting trade space analysis and collaborative exercises. Working across surface and subsurface, crewed and uncrewed platforms, you'll play a key role in shaping future maritime capability through systems-level thinking and technical leadership. You'll operate where decisions are made-translating stakeholder needs into viable platform concepts, analysing trade-offs, and coordinating multi-disciplinary inputs to support future programme direction. Key Responsibilities: Lead platform concept development based on capability requirements Develop concepts across a range of maritime platforms (crewed/uncrewed, surface/subsurface) Conduct trade space analysis (e.g. survivability, speed, automation, crew size) Undertake high-level sizing, costing, and power/propulsion estimates Produce concept cards and support analytical/tabletop exercises Assess capability gaps and define system requirements Coordinate cross-functional teams (naval architecture, systems, autonomy, cost engineering) Support certification and regulatory analysis for maritime systems Provide technical oversight, reporting, and input into design reviews Required Skills & Experience: Active SC Clearance (transferable) Engineering degree (Marine, Mechanical, Electrical or similar) Senior-level experience: 5 years post-Chartership OR 9 years relevant experience Strong background in warship or naval platform concept design Experience translating stakeholder requirements into system-level concepts Proven experience in early-stage ship design (concept/pre-concept) Knowledge of power, propulsion, and platform systems Experience in collaborative engineering and analytical exercises Desirable Experience: Multi-disciplinary team leadership on complex maritime projects Knowledge of autonomy, AI, and uncrewed systems Familiarity with certification frameworks (e.g. Lloyd's, DNV, IMO, MASS Code) Experience with electric propulsion or advanced naval systems Understanding of MoD systems engineering principles and maritime standards If you're looking to work at the cutting edge of maritime capability-where your work directly influences future platform decisions-this is a strong opportunity to step into a high-impact, concept-driven engineering role. Please note: This role requires active SC Clearance. Applicants must meet UK national security clearance eligibility requirements.
