Core Responsibilities

Primary Functions

Create detailed, production-ready 2D drawings and 3D CAD models from engineering concepts, sketches, and prototypes, ensuring all geometry, tolerances, and material specifications comply with company standards and industry best practices.
Maintain and update bills of materials (BOMs), part lists, and assembly drawings in the PLM/ERP system, ensuring accuracy of part numbers, revisions, suppliers, and purchasing information for production readiness.
Apply Geometric Dimensioning and Tolerancing (GD&T) to drawings and models to communicate functional requirements, tolerance stacks, and inspection criteria that support manufacturing and quality control.
Work directly with design engineers to translate product requirements into manufacturable designs, propose design improvements for cost, manufacturability, and performance, and document design rationale and change history.
Prepare and release controlled drawing packages and engineering change notices (ECNs) according to established revision control procedures and ISO/AS standards, coordinating with production and purchasing as needed.
Generate CNC-ready files, CAM toolpaths, and basic machining setup documentation or collaborate with CAM programmers to ensure parts are producible to specification on available equipment.
Produce detailed assembly instructions, exploded views, and installation diagrams to support production, assembly teams, and field service technicians, reducing assembly time and errors.
Conduct tolerance analysis and tolerance stack-up studies to verify interchangeability and fit of mating parts; recommend tolerance relaxation or design changes to optimize cost versus performance.
Support prototype builds by creating temporary fixtures, jigs, and tooling drawings, and by working with the shop floor to iterate designs during hands-on testing and evaluation.
Collaborate with suppliers and contract manufacturers by providing technical drawings, clarifying specifications, reviewing supplier drawings, and resolving issues that impact lead time or quality.
Perform regular drawing audits and standardization activities to ensure drawing templates, title blocks, and drafting conventions are consistent across product lines and conform to CAD standards.
Assist in root cause analysis when manufacturing or field issues arise by reviewing designs, parsing failure reports, and proposing corrective design actions and documentation updates.
Convert legacy paper drawings and hand sketches into modern CAD models and electronic drawing packages while preserving critical tolerances and functional intent.
Support DFMEA and design review meetings by preparing CAD visuals, BOM summaries, and suggested risk mitigations tied to manufacturability and assembly processes.
Create and maintain product family libraries, standard components, and reusable CAD templates to accelerate new product development and ensure design consistency.
Perform basic engineering calculations related to materials, clearances, fastener loadings, and part strength to validate design assumptions under the direction of engineers.
Produce visual aids, BOM exploded views, and photorealistic renders to support proposals, manufacturing work instructions, and marketing collateral as required.
Ensure CAD models and drawings meet regulatory and industry-specific requirements (e.g., UL, CE, ISO 9001) and support documentation needed for compliance and certification efforts.
Train and mentor junior CAD staff or shop personnel on drawing interpretation, CAD best practices, and company drafting standards to improve team competency and throughput.
Participate in continuous improvement projects focused on reducing cycle time, improving documentation quality, and standardizing design practices across engineering and production functions.
Coordinate with quality inspection teams to create inspection drawings, measurement plans, and first-article inspection documentation that align with shop capabilities and gage lists.
Troubleshoot issues with CAD data integrity, file transfer, and PLM/ERP integration; liaise with IT or CAD administrators to resolve data management problems quickly.

Secondary Functions

Support cross-functional teams during product launches by supplying last-minute drawing updates, packaging dimensions, and assembly clarifications to meet launch timelines.
Assist in vendor quotes and manufacturability reviews by preparing sample drawings, estimates of critical tolerances, and suggestions for alternate materials or processes.
Maintain spare parts drawings and update service documentation for after-sales support and customer service teams.
Participate in shop-floor observations and kaizen events to capture real-world feedback and translate it into drawing/assembly improvements.
Support procurement by verifying supplier documentation, vendor-supplied CAD models, and certificate of conformance (CoC) data for critical components.
Help maintain the CAD library, naming conventions, and folder structure to improve searchability, reduce duplication, and ensure long-term data integrity.
