About The Role

As a Senior Complex Systems Engineer (Grade 4), you will play a key role in delivering high‑quality engineering support across submarine combat systems and mission‑critical underwater complex systems. You will operate within a specialist team of Mission and Complex Systems engineers and consultants, contributing to the successful delivery of engineering projects or sub‑projects of varying scope, scale, and technical complexity.

Working both independently and as part of multi‑disciplinary teams, you will be engaged throughout the full lifecycle of customer delivery. You will collaborate closely with Project Managers to shape delivery approaches, identify and mitigate risks, develop robust project plans, and monitor and report progress against agreed schedules. You will also help to ensure effective stakeholder engagement and communication at all stages of project delivery.

In partnership with our customers, you will support the achievement of key project milestones and deliverables, particularly in relation to sustaining in‑service capabilities and developing the next generation of complex submarine combat system solutions.

Drawing on BMT’s extensive experience in defence‑related engineering, including the management and operational employment of advanced submarine combat systems, you will also contribute to the expansion of our consultancy and engineering services into emerging non‑defence underwater complex system domains.

You’re an articulate, informed, and persuasive communicator who exercises diplomacy and discretion when engaging with others—both internally and externally. You have a sharp analytical mind, able to quickly interpret complex data and use insights to identify options, make sound recommendations, and support robust, defendable decisions.

You will have actively maintained knowledge in the submarine Combat Systems area. You will be competent enough to provide detailed and specific advice regarding the application of your specialized area to both BMT internal stakeholders and our customer base.

Technical Competencies

• Comprehensive technical and/or Operational understanding of, Command, Control, Communications, Combat and Mission enabling systems.
• Preferably experienced on UK RN submarine/surface platforms.
