Mechanical Design Checker

Engineering Design Checker – Mechanical (Siemens NX / Teamcenter)

This role supports a high-visibility defense program as a Mechanical Engineering Design Checker, ensuring the accuracy, completeness, and manufacturability of complex mechanical design and drawing packages. You will work extensively with Siemens NX and Teamcenter in a largely paperless environment, applying expert-level GD&T per ASME Y14.5 and Product Manufacturing Information (PMI) to support mission-critical aerospace and defense systems. This position is on-site in Arizona and is intended as a contract-to-hire opportunity aligned with a senior Engineering Design role.

Responsibilities

• Check mechanical drawing and design packages for proper content, clarity, and completeness, ensuring compliance with applicable industry and military standards.
• Review designs for fit, function, manufacturability, and economy of fabrication, including detailed evaluation of tolerance analysis, hardware selection, and fitment on assembly prints.
• Serve as a subject matter expert in GD&T, resolving interpretation issues on drawings and providing guidance to engineers and designers.
• Verify and validate 3D models submitted to manufacturing using Siemens NX managed with Teamcenter, ensuring models and associated data accurately represent design intent.
• Model fully defined components and assemblies efficiently using Siemens NX managed with Teamcenter, adhering to established modeling best practices.
• Create and revise parametric drawings in conformance with established 3D modeling and drawing standards, including the integration of PMI (Product Manufacturing Information).
• Review mechanical drawings with appropriate personnel, verifying completed work, dimensions, materials, and quantities to be used.
• Collaborate closely with various engineering disciplines, Manufacturing, Quality, and other stakeholders to resolve design issues and ensure smooth transition to production.
• Interface with external vendors as needed to clarify design requirements, resolve technical questions, and support manufacturability.
• As requested, supervise and direct the activities of staff, providing technical oversight and mentoring on design and checking practices.
• Perform related duties as assigned or required to support program objectives, schedule commitments, and budget constraints.
• Use productivity tools such as Word, Excel, and Windows-based applications to document work, track issues, and communicate status.
• Work quickly and accurately under schedule pressure while maintaining a high level of quality and demonstrating patience and professionalism.
• Manage time and priorities effectively to meet on-time delivery metrics for drawing and model releases, supporting program schedules and cost targets.

Essential Skills

• 15–20 years of mechanical design experience in defense, aerospace, or closely related industries, with possible experience in automotive.
• At least 3 years of experience specifically as a Design Checker in DOD, aerospace, or automotive environments.
• Expert-level proficiency in Siemens NX and Teamcenter, with an indicated proficiency level of 8/10 or higher.
• Daily, hands-on use of Geometric Dimensioning and Tolerancing (GD&T) with expert-level capability, including the ability to make corrections and act as a subject matter expert.
• Thorough knowledge of GD&T per ASME Y14.5, with demonstrated recent experience applying these standards.
• Strong mechanical design and CAD background, including experience with Unigraphics NX 9.0 or later.
• Experience in DOD, military, or aerospace design environments, including work on complex mechanical and energetics systems.
• Proficiency using Siemens NX in a Teamcenter-managed environment for both 3D modeling and drawing creation.
• Ability to work effectively with PMI (Product Manufacturing Information) in a paperless program environment, consolidating written assembly/work instructions, dimensions, and data sheets into the digital drawing set.
• Strong written and verbal communication skills, including the ability to clearly explain design issues and corrections.
• Ability to work quickly and accurately under schedule pressure while maintaining high quality…
