• Experience with CAD design tools and/or best practices.

We Prefer

• Mechanical aptitude to provide solutions to a variety of technical problems of moderate scope and complexity.
• Proficiency in Microsoft Office (Word, Excel, PowerPoint) for technical analysis, data sorting/plotting, and technical documentation.
• Proficiency in utilizing CREO (Pro/E) or comparable 3D solid modeling software.
• Hands‑on experience with PTC Windchill Product Data Management or equivalent configuration and data management tools.
• Demonstrated expertise in areas such as mechanical subsystem packaging, materials science, thermal analysis, structural analysis, tolerance analysis, energetics principles, control systems, interconnect design, airframe development, or large assembly engineering.
• Exceptional interpersonal and communication skills, both verbal and written.
