Creates and modifies 2D drawings to PASA and customer standards, applying GD&T (Geometric Dimensioning and Tolerancing) principles to ensure dimensional robustness and identification of critical-to-quality dimensions as necessary. Designs plastic injection-molded components with working knowledge of draft angles, wall thickness, gate location, tooling requirements, and general part feasibility considerations, and applies knowledge of hot-plate welding design principles for plastic component assemblies, ensuring proper joint design and weld flange geometry. Designs metal stamped and metal-formed components with an understanding of forming processes, material spring-back, and tooling constraints. Designs components and assemblies utilizing cloth, paper, foam, and other pliable or soft materials, understanding their unique geometric and manufacturing constraints. Performs complex surface design work, including Class A surface creation and design studio interface coordination as directed. Imports and exports CAD data in various formats (IGES, STEP, DXF, DWG, e-Drawing, etc.) as required by engineering, purchasing, customer, and sales teams. Manages and transfers files using Siemens Teamcenter for PLM data management, including periodic file transfers to and from customer Teamcenter databases. Works within customer-specific CAD and PDM/PLM environments (Teamcenter, CATIA V6 Digital Collaboration Environment (DCE), etc.) as required by project needs. May employ quality improvement and supplier relations approaches utilizing customer-required formats such as APQP and PPAP techniques within project work, as applicable. Confers with design engineers and team leaders for design direction, accommodating multiple changes and design variations as needed. Generates CAD System BOM (Bill of Materials) structures and library components to support mechanical layouts and design data packages. Reviews data and reports for quality compliance; reacts to quality issues and takes corrective action as appropriate. Interprets specifications and job orders. Interprets and complies with Company policies, procedures, and regulations. Performs other related duties as assigned.

Experience with metal stamping and metal-formed part design, including forming process knowledge and tooling constraints. Experience designing with pliable materials such as cloth, paper, foam, and other flexible or soft substrates. Experience with complex 3D surface design techniques and design studio interface coordination. Proficiency with Siemens Teamcenter for PLM data management is required; experience working within customer Teamcenter database environments is a strong plus. Knowledge of CATIA V5 and/or V6 is preferred. Knowledge and understanding of GD&T (Geometric Dimensioning and Tolerancing) for 2D drawing creation and ease of part measurement requirements. Knowledge to import and export CAD data in various formats (IGES, STEP, DXF, DWG, e-Drawing, etc.). Experience with CAD BOM (Bill of Materials) structure, drawing creation, and engineering release processes. Proficiency with Microsoft Word, Excel, PowerPoint, and Outlook as appropriate to the position. ATTRIBUTES / SKILLS Must have the ability to read, interpret, and follow verbal and written instructions, work procedures, and other related materials. Must have the ability to learn computer applications as necessary for the position. Must successfully complete any training or certification courses required to support or strengthen the position.
