Location: Kolkata

Experience: Minimum 8 years

Qualification: B.E. / B. Tech in Mechanical Engineering

Role OverviewWe are seeking for an experienced Process Design Engineer with strong expertise in piping engineering, plant layout, pipe stress assessment and piping support structures for industrial process facilities. The role covers engineering design and coordination from front-end engineering design (FEED) through detailed design and construction support, with emphasis on secure, practical and code-compliant solutions.

Key Responsibilities• Develop and review plant layouts, equipment arrangements, plot plans and piping routes for high-pressure, high-temperature, cryogenic and utility services.

- Prepare and check piping and instrumentation diagrams (P&IDs;), pipe-sizing calculations, piping general arrangement (GA) drawings, isometrics and bills of materials (BOMs).
- Select and verify piping materials and specifications based on design pressure, temperature, fluid service and corrosion considerations.
- Design and detail pipe supports, including shoes, guides, anchors, spring hangers, trunnions and dummy legs; optimize support arrangements for constructability and performance.
- Perform or review piping flexibility and stress analyses, including sustained, thermal expansion, operating and occasional loads; verify equipment nozzle loads and support reactions.
- Coordinate the design of pipe racks, sleeper structures, equipment platforms and skids with civil and structural engineers, including relevant loading and support interfaces.
- Develop and review 2D/3D piping models,



identify clashes and resolve design interfaces with Process, Equipment, Civil/Structural and Instrumentation teams.
- Support engineering deliverables through FEED, detailed engineering and construction; address technical queries and design modifications as required.
- Ensure compliance with project specifications, applicable safety requirements and relevant engineering codes and standards, including ASME B31.1/B31.3, ASTM, API, AISC and IBC, as applicable.

Required Qualifications & Experience• B.E. / B.Tech degree in Mechanical Engineering.
- Minimum 8 years of relevant piping and plant-design experience, preferably with EPC contractors or engineering consultancies serving oil and gas, refinery, petrochemical, chemical, power or other process industries.
- Demonstrated experience in piping layouts, engineering drawings, stress evaluation, pipe-support design and multidisciplinary design coordination.

Technical Software & Standards• 3D plant design and modelling: AutoCAD Plant 3D, AVEVA PDMS/E3D or Intergraph SmartPlant 3D (SP3D).
- 2D drafting and design coordination: AutoCAD and/or MicroStation.
- Piping stress and flexibility analysis: CAESAR II and/or AutoPIPE.
- Structural/support analysis and detailing: STAAD.Pro, SAP2000 and/or Tekla Structures.
- Model review and clash coordination: Navisworks Manage; working knowledge of applicable piping and structural codes.

Preferred Credentials• Relevant training or certifications in industry design tools such as AutoCAD Plant 3D, Autodesk Inventor, CAESAR II or AVEVA PDMS/E3D.
