Job summary

CRA is seeking a Design Engineer (3D CAD) to develop detailed 3D models and drawings for process equipment, piping skids, and structural assemblies. The role requires interpreting P&IDs and engineering sketches, producing GA and isometric drawings, and collaborating with engineers and fabrication teams to ensure buildability.

Ideal candidates have 3–6 years of CAD experience, strong modeling fundamentals, and familiarity with Inventor, SolidWorks, or AutoCAD Plant 3D.

Qualifications

• 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., Inventor Studio, KeyShot, SolidWorks Visualize).
• Exposure to gas handling, skids, combustion, or pressure-based equipment.
• Understanding of 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.

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 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.

Job description

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

We are seeking a Design Engineer (3D CAD) to join our multidisciplinary engineering team. You’ll be responsible for developing detailed 3D models and layout drawings for process equipment, piping systems, and structural assemblies across CRA’s projects. The ideal candidate brings strong modeling fundamentals, experience with mechanical or process systems, and a willingness to work closely with engineers and fabricators to bring concepts to life.

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.
