CAD Product Structure Engineer

About this role

AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.

Job Description

We are seeking a detail-oriented and systems-minded CAD Product Structure Engineer to join our Engineering team. In this role, you will own the definition, integrity, and governance of product structures and bills of materials (BOMs) within our PLM/PDM environment, ensuring that CAD data accurately reflects the as-designed configuration of our products at every stage of the product lifecycle. In close coordination with Systems Engineering, you will be the central point of coordination between design engineering, manufacturing engineering, supply chain, and quality teams—bridging the gap between CAD authoring environments and the downstream systems that consume engineering data. Your ability to establish and enforce robust structure standards will be essential to maintaining configuration traceability from concept through production and service.

This position is responsible for managing the full change management workflow, including engineering change orders (ECOs), engineering change notices (ECNs), deviations, and waivers, ensuring that configuration changes are evaluated, approved, and implemented with full downstream impact visibility. You will actively manage data flows between the CAD/PLM system and enterprise platforms such as ERP, MES, and quality management systems, identifying and resolving structural discrepancies before they propagate into manufacturing or procurement. The ideal candidate combines a strong foundation in CAD modeling conventions and BOM structures with hands-on experience in configuration management processes, a methodical approach to data governance, and the communication skills to drive alignment across multidisciplinary teams.

Responsibilities

• Define, build, and maintain CAD-sourced product structures and multi-level BOMs within the PLM/PDM system, ensuring accurate part-to-assembly relationships, quantity management, and find-number assignments across all product configurations

• Manage the end-to-end engineering change management process, including initiation, impact assessment, routing, approval, and implementation of ECOs, ECNs, deviations, and waivers in compliance with established configuration management procedures

• Conduct and document configuration change impact analyses, identifying all affected drawings, models, BOMs, ICDs, and downstream deliverables prior to change authorization

• Govern the release and revision lifecycle of CAD data and associated documentation, enforcing drawing release workflows, revision control conventions, and effectivity management across single and multi-site programs

• Own the data interface between the CAD/PLM environment and downstream enterprise systems (ERP, MES, MRP), including BOM transfers, part master synchronization, and structure validation to prevent manufacturing and procurement discrepancies

• Identify, investigate, and resolve BOM and product structure discrepancies—including phantom assemblies, incorrect unit-of-measure settings, missing make/buy designations, and reference designator mismatches—before they reach production

• Establish and maintain product structure standards, naming conventions, part numbering schemas, and attribute requirements in alignment with company standards

• Support model-based definition (MBD) and digital thread initiatives by ensuring product structure integrity across 3D annotated datasets and associated metadata

• Generate and validate BOM reports, configuration audits, and as-designed vs. as-built reconciliation outputs for design reviews, supplier qualification, and customer deliverables

• Collaborate with manufacturing, quality, and supply chain stakeholders to resolve configuration discrepancies, disposition non-conformances tied to structure or BOM errors, and support first-article inspection (FAI) data packages

• Develop and deliver training on product structure standards, change management workflows, and PLM system procedures for design engineers and other system users

• Participate in continuous improvement efforts to streamline change cycle time, reduce BOM error rates, and improve data quality metrics across the product lifecycle

Qualifications

• US Citizen

• Bachelor’s degree in Mechanical Engineering, Engineering Technology, Industrial Engineering, or a related field; equivalent combination of education and relevant experience considered

• 5+ years of experience in a PLM/PDM engineering data management, configuration management, or product structure role within a manufacturing or product development organization

• Demonstrated expertise in building and managing multi-level CAD-sourced BOMs, including variant/option management, effectivity control, and complex assembly structures within a PLM environment (Windchill, Teamcenter, Enovia/3DEXPERIENCE, Agile, or equivalent)

• Solid working knowledge of engineering change management processes, including ECO/ECN workflows, deviation and waiver handling, and configuration audit practices aligned with CMII, EIA-649, or equivalent standards

• Proficiency in at least one major CAD platform (SolidWorks, CATIA, Creo, or NX) with a strong understanding of CAD file relationships, assembly constraints, and the impact of model structure on downstream BOM integrity

• Experience managing data integrations or transfer mappings between PLM and ERP/MES systems (SAP, Oracle, Infor, or equivalent), including troubleshooting synchronization failures and part attribute discrepancies

• Familiarity with configuration management planning docume
