• Supports engineering and technical reviews, including System Requirements Reviews (SRRs), Preliminary Design Reviews (PDRs), Critical Design Reviews (CDRs), Test Readiness Reviews (TRRs), Production Readiness Reviews (PRRs), and other project-specific technical reviews.
• Supports prototype fabrication and testing by incorporating approved engineering redlines, design updates, lessons learned, test-driven changes, and as-built configuration information into engineering documentation.
• Supports development and maintenance of Technical Data Packages (TDPs), including engineering drawings, CAD models, BOMs, specifications, parts lists, and supporting technical documentation.
• Provides engineering documentation support for Engineering Change Proposals (ECPs), Requests for Variance (RFVs), drawing revisions, design changes, and other configuration change activities.
• Works closely with Configuration Management to ensure drawing numbers, revisions, drawing relationships, release status, configuration identification, and associated technical documentation remain accurate, controlled, and traceable.
• Supports CM in maintaining consistency between SolidWorks models, released drawings, Windchill data, BOMs, specifications and technical documentation.
• Supports establishment and maintenance of product baselines as designs mature from development and prototype configurations toward qualification and production configurations.
• Supports Functional Configuration Audits (FCAs), Physical Configuration Audits (PCAs), and other configuration verification activities by providing accurate drawings, models, BOMs, and product definition information.
• Reviews and updates existing or legacy engineering drawings to incorporate approved design, manufacturing, test, and configuration changes.
• Supports prototype-to-production transition by ensuring engineering drawings, CAD models, and supporting technical data mature with the hardware design.
• Coordinates with engineering, testing, E7 QA, CM, and other stakeholders to resolve drawing, CAD, interface, fabrication, and hardware configuration issues.
• Maintains engineering drawings, models, and associated technical data within approved government repositories and product lifecycle management systems.
• Supports proper handling of Controlled Unclassified Information (CUI), export-controlled technical data, distribution-controlled information, and other protected technical information in accordance with Scientific and Technical Information Officer (STINFO) / applicable requirements.
• Supports a rapid weapons development and prototyping environment while maintaining appropriate engineering rigor, drawing quality, technical documentation, configuration control, and traceability.
