Mechanical Design Engineer

Mechanical Design Engineer

The Mechanical Design Engineer designs and develops complex aerospace components and assemblies using CATIA V5 and PLM tools, ensuring manufacturability, compliance with industry standards, and seamless integration at engine and vehicle levels. This role combines advanced 3D modeling, drawing creation, and configuration management with hands-on support for manufacturing, shops, customers, and vendors.

• Create and modify 3D models in CATIA V5, including sketch-based solids, complex surfaces, assemblies, and parameterized models.
• Apply manufacturing knowledge to design metallic components suitable for sheet metal forming, subtractive manufacturing, and additive manufacturing, ensuring parts can be readily produced.
• Develop details and assemblies with a broad range of complexity while working within engine- and vehicle-level digital mock-up (DMU) environments.
• Model components and assemblies using appropriate local and global coordinate systems.
• Operate within PLM software (3DX) and follow standard configuration management practices for design data and documentation.
• Generate 2D drawings and 3D PDFs for detailed components and assemblies, ensuring clarity and completeness.
• Create Model Based Definition (MBD) using the CATIA FTA workbench to capture dimensions, tolerances, and annotations directly in the 3D model.
• Develop and maintain assembly bills of materials (BOMs) that accurately reflect the design configuration.
• Apply geometric dimensioning and tolerancing (GD&T) in accordance with ASME Y14.5-2018 standards (2009 acceptable) to ensure proper fit, form, and function.
• Perform tolerance stack-ups, interference checks, and installation assessments to validate designs and mitigate integration issues.
• Write Engineering Orders and implement changes to existing drawings and models in line with configuration control processes.
• Perform weight calculations using hand methods or CATIA-based tools to support performance and compliance requirements.
• Conduct design checks and reviews of models and drawings created by other drafters to ensure accuracy, consistency, and adherence to standards.
• Support the shop, customers, and vendors by reading and interpreting SSP and customer drawings, helping to resolve questions and facilitate manufacturing.
• Create tooling models and drawings to support production, assembly, and inspection activities.
• Follow all applicable policies and procedures related to design, documentation, and quality.
• Maintain an organized, clean, and safe work area in accordance with safety standards.
• Perform other related engineering and drafting duties as assigned.

• Proficiency in all facets of 3D modeling in CATIA V5, including solids, complex surfaces, assemblies, and parameterized models.
• Strong mechanical design skills with experience in aerospace design and drafting.
• Demonstrated ability to design metallic components for sheet metal forming, subtractive manufacturing, and additive manufacturing.
• Experience working within engine- and vehicle-level DMU environments.
• Ability to model using both local and global coordinate systems.
• Hands-on experience with PLM software (3DX) and standard configuration management practices.
• Capability to create clear and accurate 2D drawings and 3D PDFs for components and assemblies.
• Experience creating Model Based Definition (MBD) using the CATIA FTA workbench.
• Strong understanding and practical application of GD&T per ASME Y14.5-2018 (or 2009).
• Ability to perform tolerance stack-ups, interference checks, and installation assessments.
• Experience writing Engineering Orders and updating existing drawings and models.
• Skill in performing weight calculations using hand methods or CATIA tools.
• Ability to perform design checks on models and drawings produced by others.
• Effective communication skills to aid shops, customers, and vendors in interpreting drawings and specifications.
• Attention to detail and commitment to maintaining organized and accurate documentation.
• Ability to maintain a safe, clean, and organized work area.

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related…
