Drawing & CAD Design Checker — GD&T Specialist

Job Description

We are seeking a highly experienced and technically rigorous CAD Design Checker to join our Spacecraft Engineering team. In this role, you will serve as the primary technical authority for the review and verification of engineering drawings and 3D model-based design across satellite programs, from concept development through launch vehicle integration. A commanding expertise in Geometric Dimensioning and Tolerancing (GD&T) per ASME Y14.5 is essential, as you will act as the final quality gate on all drawing packages for flight hardware, ground support equipment (GSE), and associated mechanical systems.

This position operates cross-functionally with satellite systems engineers, structural analysts, thermal engineers, manufacturing, and quality assurance teams to identify and resolve design discrepancies early in the product lifecycle. You will be a key contributor to maintaining drawing standards aligned with aerospace requirements and will play an active role in process improvement, lessons-learned, and mentoring junior designers on GD&T best practices in the context of space-flight applications. The ideal candidate brings a rare combination of deep drafting discipline, hands-on aerospace manufacturing knowledge, and the judgment to balance tight tolerances against producibility constraints on long-lead, flight-critical components.

Responsibilities

• Review and check engineering drawings and 3D CAD model-based designs for such components as satellite structures, mechanisms, propulsion components, and avionics assemblies for accuracy, completeness, and full compliance with ASME Y14.5 GD&T standards
• Verify that GD&T callouts are correctly applied, unambiguously defined, and achievable within satellite manufacturing and assembly constraints
• Help perform and verify detailed 1D and 2D tolerance stack-up analyses for flight-critical interfaces
• Evaluate drawings for compatibility with space-qualified fabrication processes including precision CNC machining, composite layup, chemical etching, and surface treatments (anodize, Alodine, electroless nickel)
• Issue formal redline markups and non-conformance reports (NCRs) with clear, actionable disposition for design engineers; track resolution through to drawing release
• Support design reviews (PDR, CDR, MRR) by auditing drawing packages for completeness, consistency with interface control documents (ICDs), and compliance with applicable drawing standards
• Maintain and evolve internal drawing standards, checklist templates, and GD&T training materials in alignment with program requirements and industry specifications
• Serve as the subject matter expert on GD&T interpretation and drawing standards; mentor junior designers and provide formal training on aerospace drafting best practices

Qualifications

• US Citizen
• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Engineering Technology, or a closely related field; equivalent combination of education and experience considered
• Minimum 8 years of progressive experience in mechanical design checking, detailing, or a senior drafting role, with at least 4 years in an aerospace or space systems environment
• Expert-level command of GD&T per ASME Y14.5; ASME Geometric Dimensioning and Tolerancing Professional (GDTP) certification—Senior or Technologist level—is strongly preferred
• Proficiency in at least one major aerospace-grade CAD platform (CATIA V5/V6, Creo/PTC, or NX/Siemens); experience with model-based definition (MBD) and annotated 3D datasets (PMI) is a significant plus
• Demonstrated ability to perform and verify tolerance stack-up analyses for precision assemblies
• Familiarity with satellite-specific manufacturing and assembly constraints, including clean-room protocols, handling requirements for flight hardware, and surface finish/contamination standards (ASTM, NASA-HDBK-6012 or equivalent)
• Experience with flight hardware configuration management and drawing release workflows within a PDM/PLM system (Windchill, Teamcenter, or equivalent)
• Excellent written and verbal communication skills; proven ability to document findings precisely and defend technical positions
• Demonstrated ability to collaborate effectively in a multidisciplinary team with other engineers.
• Flexibility/adaptability in a fast-paced & dynamic environment.

This job description may not be inclusive to the duties and responsibilities listed. Additional tasks may be assigned to the employee from time to time or the scope of the job may change as needed by business demands.
