In this role, you will lead and manage the end-to-end safety requirements process within the Dreadnought Combat Systems Safety Engineering Team. You will ensure safety requirements are accurately captured, decomposed, governed, and communicated across multiple stakeholders, supporting the delivery of complex submarine combat system sub-systems.

Core duties:

• Manage all safety requirements flowing from whole boat into combat systems, ensuring accurate capture, traceability, and configuration control within DOORS in a complex engineering environment
• Lead requirements decomposition activities (including DSRs, 4SFRs and 5SFRs) following Safety Team analysis, aligned with the V lifecycle model and INCOSE systems engineering principles
• Maintain robust requirements governance, change control, and configuration management across the safety lifecycle
• Provide clear, concise, and evidence-based reporting to the Senior Engineering Manager on safety requirements status, progress, risks, and compliance
• Liaise with subsystem teams, suppliers, and safety engineers to ensure alignment, consistency, and effective communication of requirements
• Support gap analysis between formal safety requirements and supplier assumptions to ensure compliance and technical integrity
• Ensure safety requirements are appropriately defined, validated, and maintained using strong systems engineering practice
• Produce high-quality technical documentation and communicate engineering decisions effectively to stakeholders at all levels

Essential Skills:

• Degree qualified in a STEM discipline or equivalent experience
• Strong understanding of safety engineering or systems engineering principles within complex engineering environments
• Experience with requirements management tools (e.g. DOORS) and configuration control processes
• Knowledge of systems engineering lifecycle and V-model development approach
• Ability to analyse, structure, and decompose complex technical requirements
• Strong communication skills with the ability to engage and influence multiple stakeholders
• Experience working in regulated or safety-critical environments (e.g. defence, maritime, nuclear, aerospace)

The Dreadnought Combat Systems Safety Engineering Team:

This team offers a unique opportunity to apply your requirements management expertise to complex submarine combat system sub-systems, working alongside experienced engineers and technical specialists across the full lifecycle of advanced defence systems. Relocation support is available for eligible Submarine roles, subject to criteria.
