Role Overview

As a Design Engineer, you will be responsible for delivering practical, buildable design solutions from concept through to fabrication and installation.

This role requires a strong understanding of fabrication detailing, steelwork design, and constructability, ensuring that all designs are not only technically correct but also feasible to manufacture, transport, and install on-site.

Key Responsibilities

• Develop and interpret P&ID (Piping & Instrumentation Diagrams) to support plant and system layouts
• Produce 2D and 3D CAD designs (AutoCAD / AutoCAD LT or similar) for fabrication and construction
• Create detailed fabrication drawings, including assemblies, sections, and material specifications
• Design structural and mechanical components such as:
  • Walkways, platforms, staircases, and handrails
  • Pipe supports, frames, and steel structures
• Ensure designs consider manufacturability, including:
  • Cutting methods and material usage
  • Welded vs single-piece fabrication
  • Bolting, fixings, gaskets, and ancillary components
• Assess transport and installation constraints, breaking designs into modular sections where required and defining assembly methodology
• Select appropriate materials (e.g. mild steel, galvanised steel, stainless steel, aluminium) based on environment and application
• Collaborate with project managers, site teams, and clients to resolve design challenges
• Produce material take-offs (MTOs) and supporting documentation
• Carry out design checks to ensure compliance with:
  • British Standards
  • Eurocodes
  • Client/asset-specific standards
• Continuously improve design efficiency, quality, and standardisation

Requirements

• Proven experience in a design engineering role within construction, water, or heavy industry
• Strong proficiency in AutoCAD (2D/3D) or similar CAD tools
• Experience producing fabrication-ready drawings (not just concept design)
• Solid understanding of:
  • Steelwork (beams, columns, connections)
  • Fabrication processes and constraints
  • Material selection for different environments
• Familiarity with P&IDs and plant layouts
• Knowledge of British Standards and Eurocodes (or ability to apply them in design work)
• Ability to design with practical installation and assembly in mind
• Strong problem-solving skills and attention to detail
• Good communication and ability to justify design decisions
