This role will include selecting, implementing, integrating and setting to work various combat system capabilities drawn from Industry partners and internally Leidos generated products. A key element of this role will be the integration of Agentic AI systems into the combat system with a strong focus on autonomous systems. Familiarity with StrikeNet and other emergent naval systems would be advantageous. The MCSE will report directly to the Maritime Chief Engineer and will be responsible for the delivery of the Combat Systems, supporting the various trials that will allow the acceptance of the new platform into service with the UK Royal Navy.

• Support bid and proposal efforts by contributing to the associated governance of the Combat Systems solution design and supporting technical proposal and costing reviews.
• Conduct trade studies and support design reviews to assess system performance, scalability, and interoperability.
• Support the provision of governance and oversight across engineering delivery to ensure technical alignment and integration across maritime opportunities.
• Stay abreast of emerging and cutting‑edge technologies and industry trends to drive innovation and system improvement including but not limited to uncrewed systems, advanced comms and AI.
