• 1 to 3+ years of mechanical design experience, preferably in a product development or defense industry environment.
• Proficiency in Autodesk Inventor (or equivalent 3D CAD software) for part, assembly, and drawing creation.
• Experience designing for manufacturability, assembly, and cost (DFM/DFA/DFC).
• Hands-on experience with mechanical prototyping, including machining, 3D printing, and assembly.
• Familiarity with thermal and structural analysis methods and tools (e.g., SimScale, SolidWorks Simulation, ANSYS etc).
• Strong understanding of material selection, tolerance stack-up, and mechanical fastener design.
• Ability to work independently and within a cross-functional engineering team environment.
• Excellent communication, documentation, and organizational skills.
• Must have outstanding attention to detail, problem solving and self-starter abilities to not only start new tasks but ask for assistance or guidance when problems emerge.

Nice To Haves
