- Provide desk-side and remote support to design engineers, troubleshooting CAD, data management, and performance issues quickly to keep hardware programs moving
- Develop and deliver training for engineers on NX best practices, workflows, and Castelion standards
- Build and maintain NX templates, drafting and modeling standards, and customer defaults
- Automate repetitive engineering tasks using NX Open, journals, and Knowledge Fusion
- Enable model-based definition (MBD) and PMI practices to support manufacturing, inspection, and supplier data packages
- Support NX CAM users and post-processor configuration as needed
- Coordinate with ECAD (Altium) users and tool owners to ensure smooth MCAD/ECAD coexistence and data exchange
- Create and maintain documentation for configurations, procedures, and known issues
- Serve as primary liaison with Siemens support and resellers, managing tickets, escalations, and roadmap discussions
Basic Qualifications - 5+ years of experience administering or supporting Siemens NX in an engineering environment
- Hands-on experience with NX/Teamcenter integration and Teamcenter administration concepts
- Experience with NX licensing, installation, deployment, and version upgrades
- Strong troubleshooting skills and a customer-first mindset when supporting engineers
- Experience in aerospace, defense, or other hardware-focused industries

- Experience with BMIDE, Active Workspace, and Teamcenter workflows
- Experience implementing MBD/PMI in a production environment
- NX CAM and post-processor experience
- NX Routing experience (Routing Electrical for 3D wire harness design, Routing Mechanical for tubing/piping), ideally alongside Siemens Capital (Capital Harness Design / Formboard)
- Experience with Siemens Fibersim for NX (composite ply design, flat patterns, and manufacturing outputs such as ply nesting and laser projection)
- Familiarity with Altium Designer and MCAD/ECAD collaboration
- Experience supporting engineering IT in a CMMC / NIST 800-171 or ITAR-controlled environment
