CAD Designer

Functional Activities – Specific Responsibilities

• A. Detailed Drawing Preparation

  Prepare detailed 3D CAD models, assemblies, and engineering drawings for aerospace structures, propulsion components, test articles, and ground support equipment under the guidance of senior designers. Produce complete drawing packages including part drawings, assembly drawings, and associated BOMs, ensuring compliance with applicable drafting standards and internal drawing conventions.

• B. Tolerancing and GD&T

  Apply GD&T principles to define dimensions, tolerances, surface finish, and inspection requirements on manufacturing drawings for aerospace components. Perform tolerance stack‑up analysis to ensure correct fit, alignment, and assembly. Review drawings for conformance with machining, fabrication, welding, and assembly constraints and coordinate with the design team to resolve manufacturability issues prior to drawing release.

• C. Supplier Liaison and On‑Site Support

  Act as the primary point of contact with manufacturing suppliers and subcontractors, visiting supplier facilities to follow up on production progress, clarify drawing requirements, and ensure technical intent is correctly understood and implemented. Conduct incoming inspection of manufactured parts against engineering drawings, flag non‑conformances, and work with suppliers to agree and document disposition, including concessions and rework instructions under the guidance of the responsible engineer.

• D. Drawing Control and Technical Documentation

  Maintain drawing registers and support document control activities, ensuring drawings are correctly numbered, revised, and issued in accordance with the program’s configuration management process. Prepare and update BOMs and assembly instructions. Support design reviews including PDR, CDR, and manufacturing readiness reviews by preparing drawing packages and ensuring traceability between requirements, design decisions, and final drawings.

• E. Support to Integration and Testing Teams

  Support test article preparation, hardware assembly, and integration activities, working alongside propulsion, structures, instrumentation, and test teams. Assist with troubleshooting of fit and assembly issues identified during integration. Relay feedback from integration and testing activities back to the design team and support the incorporation of lessons learned into updated drawings and documentation.

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field, with 2–5 years of relevant experience in mechanical design or manufacturing engineering.
• Working proficiency in 3D CAD modelling (preferably Inventor) and preparation of detailed manufacturing drawings in accordance with aerospace or engineering industry drafting standards.
• Good understanding of GD&T, tolerancing principles, and tolerance stack‑up, with the ability to apply them correctly to aerospace or high‑performance mechanical components.
• Familiarity with common manufacturing processes (machining, fabrication, welding, assembly) and the ability to engage effectively with suppliers and machine shops to resolve drawing queries and manufacturing constraints.
• Willingness to travel to supplier facilities and work on‑site to support manufacturing follow‑up, parts inspection, and integration activities.
• Strong interpersonal and communication skills to liaise effectively with external suppliers and internal engineering teams.
