3D Designer (Mechanical)

About CRA

CRA designs and manufactures custom-engineered systems for the Energy and Defence sectors. We deliver complex projects end-to-end, entirely in-house, combining design, engineering, and manufacturing under one roof. Our systems are trusted by leading organisations including BrahMos Aerospace, ONGC, Indian Air Force, and Schlumberger.

Role Overview

You will build 3D models of CRA's process equipment and skid packages, and produce the GA and fabrication drawings from them. You will work from engineers' datasheets, P&IDs and sketches, and from vendor drawings. Your models go to clients for approval and to our fabrication shop, so accuracy and buildability are the core of the job.

Key Responsibilities

• Build 3D models of vessels, stacks, combustion chambers, scrubbers, skids and containerised systems from engineers' inputs
  
• Route skid piping to the P&ID, placing valves, fittings and supports for operation and maintenance
  
• Model skid frames and structures in standard sections, including lifting points and transport limits
  
• Model vendor equipment from outline drawings and check its interfaces against the P&ID and layout
  
• Produce GA and fabrication drawings from the models, with dimensions, weld symbols, BOMs and cut lists
  
• Check models for clashes, access and nozzle orientation before release
  
• Keep models organised to CRA's standards for assembly structure, part numbers, materials and revisions
  
• Raise queries where inputs conflict, and incorporate client comments and site markups
  
• Work with process, mechanical and E&I engineers and the fabrication shop so designs are practical to build.
  
  

Requirements

• Diploma or B.E./B.Tech in Mechanical Engineering
  
• 3 to 7 years of 3D design of process equipment, skids or fabricated structures with an OEM, fabricator or EPC
  
• Expert in SolidWorks, Inventor or a similar parametric 3D tool, including assemblies, weldments or frames, sheet metal and drawings
  
• Experience routing piping in 3D, and able to read P&IDs and vendor drawings
  
• Working knowledge of fabrication: standard plate, pipe and steel sections, ASME B16.5 flanges and B16.9 fittings, weld symbols and tolerances
  
• Proficient in AutoCAD for 2D work
  
• Preferred: P&ID drafting; pressure vessels, flares or combustion equipment; compressor and blower skids
  

Shortlisted candidates will be asked for sample models and drawings and a hands-on 3D design test.
