This is an on-site position in our Livermore, CA office and reports to the Product Lifecycle Management (PLM) Manager.

IN THIS ROLE YOU WILL

• Create and maintain detailed 3D models, assemblies, installations, and 2D drawings for bus components and sub-systems using Siemens NX
• Apply mechanical design principles, including tolerance stack-ups, interface definition, and packaging, with emphasis on manufacturability, assembly, and serviceability
• Process redlines and engineering change revisions in collaboration with Engineering and Manufacturing teams
• Develop, maintain, and administer the Standard Parts Library in Teamcenter/NX, ensuring accuracy, completeness, and compliance with CAD standards
• Create, classify, and validate standard part records (fasteners, seals, clips, grommets, etc.) according to naming conventions and engineering guidelines
• Audit the library to identify and eliminate duplicate, obsolete, or incomplete entries
• Establish, document, and enforce CAD modeling, drawing, and file naming standards across Engineering
• Coordinate with Engineering, Procurement, and other teams to ensure standard parts align with sourcing and design requirements
• Perform self-checks and peer reviews to ensure designs and documentation meet GILLIG standards
• Maintain version control, data integrity, and compliance within Teamcenter and internal quality processes
• Identify opportunities for automation and process improvement within CAD and PLM workflows
• Promote design standardization and reuse to reduce part proliferation and increase engineering efficiency

BASIC QUALIFICATIONS
