Senior Structural Engineer - Subsea Systems / Heavy Mechanical Design
Blyth, Hybrid
£65,000 - £75,000 basic + benefits

An exciting opportunity has arisen for an experienced Senior Structural Engineer to join a leading engineering and technology organisation developing innovative subsea and offshore trenching systems.

You'll be assisting with the design of a new trencher & taking ownership of structural and mechanical design projects from concept through to manufacturing +working closely with multi-disciplinary teams to deliver robust, safe, and efficient engineered solutions for use in challenging marine environments.

Key Responsibilities:
- Lead the structural and mechanical design of subsea and offshore equipment, including ROV trenching systems and related components.
- Produce detailed engineering calculations, drawings, and technical documentation (AutoCAD, Inventor, MathCAD).
- Carry out FEA and structural analysis (plates, shells, beam theory, STAAD Pro).
- Conduct and review FMECA, HAZOP, and safety-by-design assessments.
- Perform stress analysis, material selection, and welding/plating design for harsh environments.
- Support Factory Acceptance Testing (FAT) and System Integration Testing (SIT) activities.
- Collaborate with engineers across electrical, hydraulic, and control disciplines to ensure seamless integration.

About You:
- Degree-qualified in Structural Engineering, Mechanical Engineering, or a related discipline.
- Proven experience designing structural or mechanical systems for subsea, offshore, or heavy industrial applications.
- Strong proficiency in 2D/3D CAD (AutoCAD, Inventor, MathCAD) and FEA tools.
- Sound understanding of DNV design codes for lifting appliances and marine operations.
- Confident with free-body diagrams, strength of materials, and stress calculations.
- Able to check and approve structural calculations and design documentation.
- Excellent communicator with strong organisational and teamwork skills.

Desirable Experience:
- Prior involvement in ROV, trenching tool, or subsea handling system design.
- Working knowledge of hydraulics, mechanisms, and power transmission systems.
- Experience with fabrication, machining, and assembly drawings for welded structures.
- Understanding of corrosion protection, hydraulic sealing, and material selection for subsea use.
