• Create and revise 3D designs and 2D drawings in accordance with internal and customer requirements, using CAD tools such as CATIA V5, NX, or equivalent software.
• Self-check and review all designs and drawings prior to final release, ensuring completeness, accuracy, and compliance with standards and requirements.
• Follow established design procedures, complete required forms, and close all actions associated with internal and customer design processes and reviews.
• Apply engineering skills in drawings, design, and technical publications, and develop capabilities in advanced analysis, concepting, and stress analysis with appropriate support.
• Develop and refine technologies related to machine design and integration, jigs and tools, platforms, and operations, while building knowledge in controls.
• Work autonomously in software tools such as CATIA and GURU for 3D CAD design, modeling, and documentation.
• Build personal and leadership capabilities in areas such as leading small teams, customer interface, process-based thinking, requirements management, and scheduling and estimation.
• Field telephone calls and respond to inquiries from build suppliers and shop personnel regarding mechanical design engineering problems and related issues.
• Ensure all design changes, design change notices (DCNs), and as-built information are properly incorporated into drawings and documentation.
• Select, record, file, and maintain all component information for concepts and designs, ensuring traceability and configuration control.
• Perform component and material sizing for designs and request or provide input to cognizant stress analysis engineers as needed.
• Perform hand calculations and stress analysis, and solicit review and checks from cognizant engineers to validate design integrity.
• Use and interpret GD&T, schematics, and engineering documentation to ensure designs are manufacturable, functional, and compliant with specifications.
• Coordinate closely with electrical and software groups, attend controls reviews, and provide mechanical design input as required.
• Provide leadership to establish and meet design schedule goals, including planning tasks, monitoring progress, and adjusting priorities as needed.
• Perform peer checks of designs and drawings as required, providing feedback and ensuring adherence to standards and best practices.
• Understand and follow safety and environmental regulations and identify safety and environmental concerns within designs and processes.
• Adhere to the Quality System and participate in continuous improvement initiatives related to design processes, tools, and documentation.
• Support design reviews, customer interface meetings, and supplier coordination activities to ensure alignment on requirements, schedules, and deliverables.
• Contribute to the full project lifecycle, from concept and design through commissioning and customer delivery, ensuring a smooth transition into production.
• Perform other engineering duties as assigned to support program, department, and organizational objectives.

Work Environment

The role is based in an indoor, office environment that is temperature controlled and designed for engineering work. The engineer spends prolonged periods sitting at a desk and working on a computer, using 3D CAD tools such as CATIA V5, NX, or equivalent software, as well as FEA tools like ANSYS or Femap. The work involves light physical demands, including moving objects up to 20 pounds and frequent use of fingers for typing, mouse use, and detailed computer work. No adverse environmental conditions are expected in the normal course of work. The position follows a standard work schedule, with overtime occasionally required to meet project deadlines, support required travel, or address emergent conditions. Travel may be required up to approximately 20% of the time to support on-site integration, commissioning, supplier visits, or customer meetings. Engineers work alongside experienced tooling and automation engineers in collaborative engineering groups that are large enough to support teamwork yet small enough to provide individual visibility and influence over project outcomes. The culture emphasizes multidisciplinary collaboration, direct interaction with leadership, strong mentorship, and continuous technical and leadership development while working on cutting-edge aerospace automation technologies.
