Senior Engineer, Mechanisms (R4890)

Shield AI is seeking a Senior Engineer, Mechanisms to contribute to the mechanical design and development of its autonomous UAV products.

As a Mechanical Engineer, you will be responsible for designing and developing state-of-the-art AI and aircraft products. You will help architect new products, perform detailed design of complex electro-mechanical assemblies, and use best-in-class design and analysis tools.

Responsibilities:

• Design complex electro-mechanical mechanisms for autonomous aircraft
• Own the full design process: concept, CAD, tolerance analysis, material selection, and drawing release
• Perform structural and kinematic calculations and preliminary FEA
• Prototype, test, and iterate mechanism designs for functionality and reliability
• Collaborate with electrical, avionics, flight controls, and propulsion teams
• Support pre-production builds, prototype integration, and ground/flight testing

Requirements:

• B.S. in Mechanical/Aerospace Engineering
• 5+ years in mechanical or mechanism design
• Strong CAD skills (NX preferred)
• Kinematic analysis and optimization
• Structural analysis utilizing hand calculations and finite element methods
• FEA analysis: Modal, non-linear and linear, buckling, fatigue
• GD&T and tolerance stack-ups for mechanical systems
• Materials selection inclusive of alloys, heat treatments, allowables, and finishes
• Ability to work independently in fast-paced, cross-functional teams
• A demonstrated record of working hard, being trustworthy, holding yourself to high standards, and being kind to others

Preferred qualifications:

• Experience with UAVs, aircraft, or robotic systems
• Familiarity with electro-mechanical actuators
• Proficiency in FMEA, DOE, and root cause analysis
• Hands-on machine shop or mechanic experience (professional or hobby)
• RTCA DO-160, MIL-STD-810, structural, or actuated mechanism testing experience
• Ability to thrive in startup, R&D, or defense innovation environments
