Lead Mechanical Design Engineer

Place of Posting

Energy House, Pune

Key Objectives The Piping Designer will be responsible for piping layout design, 3D modelling, engineering, optimization, and documentation for green hydrogen generation packages, including Alkaline, PEM, and Solid Oxide Electrolyser (SOEC) systems, Balance of Plant (BoP) equipment, and associated utility systems.

The role involves supporting engineering activities from concept development and basic engineering through detailed design, fabrication, installation, and commissioning, while ensuring safety, reliability, maintainability, constructability, and compliance with applicable industry codes, standards, project specifications, and quality requirements.

Major Deliverables

- Piping Design and 3D Modelling

Develop and maintain 3D piping models using CADWorx Plant Professional based on P&IDs;, equipment layouts, plot plans, piping specifications, and project design criteria. Prepare piping layouts, general arrangement (GA) drawings, piping isometrics, support drawings, and material take-offs (MTOs).

Ensure proper routing, equipment accessibility, maintenance clearances, operability, and constructability.

- CADWorx Configuration and Specification Management

Configure and maintain CADWorx project settings, piping specifications, catalogues, component data, and project configuration files. Update component dimensions, material grades, pressure classes, and data tables as per approved project requirements.

Troubleshoot modelling, specification loading, and configuration-related issues.

- ISOGEN Configuration and Isometric Generation

Configure ISOGEN settings, drawing styles, title blocks, annotations, dimensions, and material tables as per project standards. Generate, check,



and revise piping isometric drawings and associated material reports.

Resolve isometric generation errors and ensure consistency between 3D models and issued drawings.

- 3D Model Review and Clash Detection

Review and coordinate multidisciplinary 3D models using Autodesk Navisworks. Perform clash detection and coordinate resolution of piping, equipment, structural, civil, electrical, and instrumentation interfaces.

Incorporate approved model review comments and ensure design accuracy and constructability.

- Piping Design Engineering and Standards

Interpret P&IDs;, piping material specifications, line lists, equipment drawings, and applicable engineering standards. Apply relevant piping codes, including ASME B31.3, ASME B31.12 and project-specific specifications, as applicable.

Coordinate with piping stress engineers to incorporate support locations, flexibility requirements, and equipment nozzle load limitations.

- Engineering Deliverables and Quality Control

Prepare, check, and issue piping design deliverables in accordance with project schedules and quality requirements. Verify consistency between 3D models, P&IDs;, piping specifications, isometrics, and MTOs.

Maintain drawing registers, revision records, model review comments, and project documentation.

- Project Coordination and Execution

Coordinate with process, mechanical, piping stress, civil, structural, electrical, and instrumentation teams to resolve design interfaces.



Execute assigned piping design activities independently, with minimal supervision.

Incorporate approved design changes and provide technical support for fabrication, construction, and site-related queries.

Support junior designers and contribute to improving design quality and productivity.

- Software Skills and Technical Competencies

Hands-on experience in CADWorx Plant Professional for 3D piping modelling and drawing extraction. Working knowledge of ISOGEN configuration and isometric generation.

Experience in CADWorx project configuration, specification management, catalogue maintenance, and data table updates.

Proficiency in Autodesk Navisworks for model review and clash detection, and AutoCAD for 2D drafting.

Valuable understanding of piping components, piping material specifications, engineering drawings, and applicable design standards.

Strong coordination, problem-solving, and technical communication skills.

- Critical Competencies and Essential Attributes

Strong knowledge of piping design, layout engineering, and 3D modelling for green hydrogen generation packages, including Alkaline or SOEC electrolysers and associated Balance of Plant (BoP) systems. Hands-on experience with CADWorx, AutoCAD Plant 3D, AutoCAD, and related piping design tools.
