Sr. 3D CAD Designer

SENIOR 3D CAD DESIGNER

GMM Pfaudler Systems | Process Systems Technologies | Rochester, New York

Design the process systems that industry depends on.

This is not a typical CAD drafting position. You will transform process concepts into complete, construction-ready modular systems and see your designs progress from initial layout through fabrication and as-built documentation.

SUMMARY OF POSITION

GMM Pfaudler US Inc. is a leading supplier of highly engineered, critical equipment and process systems for energy, chemical, and industrial markets. The Process Systems Technologies (PST) group designs and fabricates complete modular process systems, including Reactor Systems, Wiped Film Evaporator (WFE) Systems, Distillation Systems, and other specialized process systems.

We are seeking an experienced 3D CAD Piping Designer to join the PST Group as a Senior 3D CAD Designer. The position is based in our Rochester, NY office, with remote or hybrid arrangements considered for highly qualified candidates based on experience and demonstrated capabilities.

Every system we design is custom engineered for a client's specific process and production needs. Our work serves a broad range of industries, including specialty chemicals, pharmaceuticals, nutraceuticals, petrochemicals, polymers, and others. Projects may involve scaling laboratory or pilot-test data into a commercial production system or evaluating and improving an existing process to increase capacity, product quality, operability, and maintainability.

The variety and scale of the work make this an unusually broad design role. Projects range from compact skid-mounted units to large, multi-level modules and combined modular systems. The Senior 3D CAD Designer brings the complete system together by modeling structural steel, process equipment, piping, valves, and instrumentation, then producing the fabrication drawings and bills of materials required to build it.

WHY THIS ROLE IS DIFFERENT

• Own meaningful design work rather than simply drafting someone else's completed concept.
• Work on custom projects across multiple process industries, with new layout and routing challenges on each assignment.
• Collaborate directly with Process Engineers, Project Engineers, equipment vendors, fabrication personnel, and customers.
• Balance equipment arrangement, piping design, instrumentation, structural support steel, access, constructability, and maintainability in one integrated model.
• Follow your work through the full project lifecycle, from P&IDs and early layouts through fabrication support, inspection, and final as-built documentation.
• See the systems you model become real operating process plants.

ESSENTIAL DUTIES AND RESPONSIBILITIES

The Senior 3D CAD Designer serves as the primary modeling and detailing resource for assigned PST process-system projects. PST systems are typically skid mounted or modular. Modules may range from approximately 3 ft W x 4 ft L x 5 ft H base-level skids to approximately 12 ft W x 14 ft L x 60 ft H structures with multiple operating levels, platforms, and access stairs. Large projects may consist of multiple interconnected modules. Working closely with Process and Project Engineers, the Designer develops fully integrated 3D models and construction documentation for systems that combine process equipment, piping, instrumentation, structural steel, access platforms, and utilities. Essential duties include the following; other duties may be assigned as necessary.

• Work with Process and Project Engineers (PEs) to create and maintain 2D Piping and Instrumentation Diagrams (P&IDs) and Process Flow Diagrams (PFDs).
• Use equipment specification sheets and vendor information to model process equipment in 3D by creating custom parts, using GMM Pfaudler's existing library of user shapes, or incorporating suitable vendor stp file.
• Use instrument specification sheets and vendor information to model instruments in 3D by creating custom parts, using existing library shapes, or incorporating suitable vendor stp files.
• Develop (rough-in) preliminary 3D models of structural-steel support skids and equipment-support structures using Autodesk Plant 3D "piper's steel. This includes the steel needed to support equipment, piping, operating platforms, and access requirements.
• Develop and coordinate the complete 3D system model in Autodesk Plant 3D, including process equipment, instruments, valves, and all interconnecting process and utility piping.
• Arrange equipment and route piping to address process requirements, accessibility, operability, maintenance, fabrication, transportation, and installation constraints.
• Use Autodesk Advance Steel and the coordinated model to create 2D detailed structural-steel layout drawings required by the fabrication shops.
• Create 2D orthographic piping drawings, plans, and elevations showing module arrangements, overall dimensions, equipment locations, and field tie-point locations.
• Create 2D and 3D piping isometric and spool drawings for each pipeline, including the information required for fabrication and assembly.
• Export equipment, piping, valve, instrument, and structural-steel bills of materials to Excel for engineering review, procurement, and shop construction.
• Coordinate model interfaces and resolve clashes or inconsistencies among equipment, piping, instrumentation, structures, platforms, and access features.
• Participate in internal and customer design reviews, incorporate approved comments, and maintain accurate revisions throughout the project.
• During fabrication, work with the PE and shop personnel to troubleshoot construction issues and implement approved design changes.
• Review the fabricated system and update the final 3D model, drawings, and documentation to reflect as-built conditions.
• While not a requirement, preference will be given to candidates with the ability to perform selected CAD-administration activities, such as maintaining or improving project templates, modifying piping specifications, updating catalogs, and creating custom parts.

WHAT MAKES A SUCCESSFUL CANDIDATE

• Enjoys solving complex equipment-layout, access, constructability, and piping-routing challenges.
• Takes pride in accurate, well-organized, construction-ready models and drawings.
• Prefers varied custom-project work over repetitive production drafting.
• Communicates well with engineers, designers, vendors, customers, and fabrication personnel.
• Can work independently, manage design details, and collaborate as an active member of a project team.
• Is curious, practical, detail-oriented, and willing to follow a design through fabrication and completion.

SUPERVISORY RESPONSIBILITIES

None.

QUALIFICATIONS

Experience Requirements

• A minimum of ten (10) years of relevant piping-design and 3D-modeling experience, including a minimum of five (5) years using Autodesk Plant 3D.
• A minimum of five (5) years of experience with preliminary or "rough-in" design and 3D modeling of structural-steel equipment-support structures. Experience limited to pipe racks does not satisfy this requirement.
• A minimum of two (2) years of experience detailing steel is preferred.
• A minimum of two (2) years of experience using Autodesk Advance Steel is preferred.
• Piping-design and modeling experience in the chemical or pharmaceutical industry is required.
• Working familiarity with process equipment, valves, and instrumentation commonly used in chemical-process systems is required.
