Job description

Location: GreaterLondon, UK
Working Pattern: Full-time, office-based (5 days per week)
Contract: Permanent / Staff
We are seeking an experienced Senior CAD Designer to join our London-based team in Sutton. Working closely with the Deputy Drawing Office Manager, you will be responsible for developing detailed engineering and fabrication drawings for complex offshore and subsea structures.
The role will involve working primarily with Autodesk Inventor and AutoCAD, supporting projects from the design stage through to fabrication and installation, while working closely with engineering and fabrication teams to ensure practical, clash-free solutions.
Key Responsibilities

• Produce detailed design and fabrication drawings for subsea and offshore steel structures using Autodesk Inventor and AutoCAD.
• Develop offshore installation sketches, lifting arrangements and rigging drawings to support project execution.
• Work closely with engineering and other disciplines to incorporate design requirements and ensure drawings are fully coordinated and free from clashes.
• Identify potential design or technical issues and work with the wider team to develop effective and practical solutions.
• Carry out thorough self-checking and peer/team reviews of drawings and design documentation.
• Ensure all drawings meet appropriate engineering standards and comply with internal drawing office procedures and quality requirements.
• Provide technical support to fabrication teams, helping to resolve design-related issues, constructability challenges and clashes encountered during fabrication.
• Manage multiple drawing and design requirements while maintaining quality and meeting agreed project deadlines.

About YouWe are looking for someone with a strong background in subsea or offshore structural design, rather than a traditional piping design background.
Ideally, you will have:

• A technical qualification or education in Mechanical Engineering, Structural Engineering, Civil Engineering, or a related discipline.
• Significant experience in CAD design and drafting of subsea steel structures within the marine, offshore or oil & gas sectors.
• Previous experience operating at Senior Designer / Senior CAD Designer level.
• Strong practical experience with Autodesk Inventor, including iLogic functionality.
• Excellent working knowledge of AutoCAD.
• The ability to understand engineering requirements and translate them into accurate, fabrication-ready drawings.
• Experience working within multidisciplinary engineering and project teams.
• Strong organisational skills, with the ability to manage competing priorities and deliver work within project deadlines.
• Good general IT skills, including Microsoft Excel, Word and PowerPoint.

Important: This position is not focused on piping design. We are specifically looking for candidates with experience in subsea structure layouts, subsea steel structures and offshore fabrication/design.
