Systems Engineers x2; Propulsion

We are seeking an experienced Systems Engineer with strong propulsion domain knowledge to support a major defence maritime programme. The role sits within a multidisciplinary engineering team developing and integrating propulsion systems for naval platforms including surface ships and/or submarines.

This is a long-term opportunity suited to an engineer with experience across the propulsion lifecycle-requirements, design, performance analysis, verification/validation, and stakeholder engagement.

• Develop, refine, and manage systems requirements for propulsion systems across the project lifecycle.

• Support propulsion concept development, system architecture definition, and integration activities.

• Conduct system-level assessments including performance analysis, functional modelling, and trade studies.

• Work with specialist propulsion engineers (mechanical, electrical, controls) to ensure coherent system design.

• Produce and review technical documentation including requirements sets, interface definitions, specifications, and design justification material.

• Support V&V planning, test readiness, acceptance criteria development, and review of qualification evidence.

• Assist in developing and maintaining propulsion system architectures, block diagrams, and interface models.

• Engage with internal stakeholders, suppliers, and customer representatives to ensure technical alignment.

• Participate in design reviews, technical workshops, hazard analyses, and risk assessments.

• Contribute to the integration of propulsion systems with platform-level systems such as power/energy, cooling, auxiliaries, control systems, and safety systems.

• Background in systems engineering, ideally in a defence or safety-critical environment.

• Proven experience with propulsion systems in maritime, naval, or submarine platforms.

• Strong understanding of whole-system engineering including requirements, integration, verification, and configuration control.

• Familiarity with propulsion subsystems such as:

  • Prime movers (diesel, gas turbine, electric drive)

  • Shaftline systems

  • Power transmission

  • Cooling and auxiliary systems

  • Control & monitoring systems

• Ability to interpret technical drawings, schematics, and system models.

• Experience with systems engineering tools such as DOORS, Cameo, Rhapsody, Enterprise Architect, or equivalent.

• Experience working on submarine propulsion or integrated electric propulsion (IEP).

• Knowledge of safety and certification requirements for naval platforms.

• Experience producing design justification evidence or safety case inputs.

• Knowledge of model-based systems engineering (MBSE).
