Job Description
The Submarine Delivery Agency (SDA) is part of the Ministry of Defence responsible for the procurement, in-service support, and disposal of the UK’s nuclear submarines. Our work is critical to maintaining the UK’s Continuous At-Sea Deterrent (CASD) and delivering some of the most complex engineering programmes in defence.
The Forward Design Group (FDG) sits at the forefront of future submarine capability, leading early-stage design, concept development, and system-level integration for next-generation platforms. FDG plays a central role in shaping requirements, informing major investment decisions, and enabling coherence across programmes such as; Ship Submersible Ballistic Nuclear (Replacement) (SSBN(R)), Nuclear Propulsion Plant X (NPPX) and Naval Design Partnership (NDP) activities.
We are seeking an experienced Level 3 Engineer – Combat Systems & Stealth (SEO equivalent) to lead “fight” capability development within FDG. This role focuses on the integration and performance of combat systems and stealth characteristics at platform level, ensuring future submarines remain operationally effective and survivable in contested environments.
The FDG L3 Fight Engineer is responsible for leading combat systems and stealth input across early-stage submarine design activities. This includes shaping how the platform detects, communicates, survives, and fights — ensuring these elements are coherently integrated within the overall system.
The role operates in a concept and pre-concept environment Low Technology Readiness Level (low TRL), where influence, system-level thinking, and the ability to manage ambiguity are critical.
Key Responsibilities
- Lead development of combat systems and stealth concepts across Forward Design activities, covering sensors, communications, weapons integration and survivability.
- Define and influence platform-level “fight” architectures, aligned to operational needs and evolving threat environments.
- Embed stealth considerations (acoustic and non-acoustic) early in design to ensure survivability is integral, not retrospective.
- Assess the combat systems and stealth landscape, including current capabilities, emerging technologies and threat drivers to inform future design direction.
- Apply spiral development principles, ensuring future platforms are designed to evolve capability incrementally over time.
- Develop and support long-term technology roadmaps for next-generation and generation-after-next submarine capability.
- Lead and assure trade studies, balancing performance, risk, cost and integration to inform early-stage decisions.
- Drive cross-discipline integration and act as an intelligent customer, working with internal teams and industry to shape coherent, deliverable concepts.
