Design Engineer (3D CAD)

CRA is a purpose-driven engineering firm with over 30 years of experience designing and manufacturing custom-built systems for the Energy and Defence sectors. Our work spans biogas systems, flaring and combustion packages, and complex weapon handling systems — all engineered in-house for durability, reliability, and performance in demanding environments.

Role Overview

Design Engineer (3D CAD)

Experience with Autodesk Inventor and/or AutoCAD Plant 3D is a strong advantage — but not a strict requirement. Experience with rendering tools to generate photo-realistic visuals is also preferred, but not mandatory.

Key Responsibilities

• Develop detailed 3D CAD models of process equipment, piping skids, structural frames, and mechanical assemblies.
  

• Interpret P&IDs, process flow diagrams, and engineering sketches to build accurate models.
  

• Produce GA drawings, isometric drawings, fabrication details, and Bill of Materials (BOMs).
  

• Coordinate closely with project engineers, drafters, and the manufacturing team to ensure buildability.
  

• Participate in design reviews and incorporate feedback efficiently.
  

• Follow engineering standards and drawing practices (e.g., ASME, ISO, ANSI).
  

• Maintain a clean model structure with consistent layer management and part naming.
  

• Assist in design documentation, model version control, and change management.
  

• (Preferred) Create high-quality renders or animations of designs for marketing, client presentations, or internal documentation.
  

• Diploma / B.Tech in Mechanical Engineering or related discipline
  

• 3–6 years of experience in 3D CAD modeling, preferably in process equipment or industrial systems
  

• Hands-on experience with Autodesk Inventor, SolidWorks, or similar 3D CAD software
  

• Familiarity with AutoCAD Plant 3D is a plus
  

• Experience creating photo-realistic renders (e.g., using Inventor Studio, KeyShot, SolidWorks Visualize) is preferred
  

• Exposure to gas handling, skids, combustion, or pressure-based equipment is a strong advantage
  

• Understanding of standards such as ASME B31.3, API, ISO, and fabrication tolerances
  

• Strong problem-solving skills and attention to detail
  

• Comfortable working on multiple projects simultaneously with a proactive attitude
  

• group medical insurance

• leave policy

• learning opportunities

• in-house manufacturing

• Supportive work culture focused on innovation and reliability
