Shield AI, a venture-backed defense-tech company, is seeking a Staff Engineer to lead landing gear systems design for the Ranger (R6294) autonomous aircraft platform. You will own the full technical lifecycle of landing gear development, from architecture definition through flight test support.
Key responsibilities include:
• Architecture and Kinematic Trades: Lead landing gear architecture definition and trade studies (electro-mechanical vs. hydro-mechanical actuation, fixed vs. retractable kinematics, stowage packaging) to meet vehicle mass, volume, and ground handling requirements.
• Mechanism and Structural Design: Own the complete CAD design lifecycle from initial concept through drawing release, including complex linkage kinematics, clearance envelopes, structural load paths, material selection, and rigorous tolerance stack-ups.
• Structural and Dynamic Sizing: Perform first-principles classical stress and fatigue hand calculations, backed by finite element analysis (linear/non-linear, modal, buckling) and dynamic landing load assessments.
• Subsystem Sizing and Selection: Size and select wheels, tires, brakes, shock absorption systems, actuators, and nose wheel steering mechanisms tailored to vehicle landing and taxi envelopes.
• Component Sourcing and Vendor Management: Author technical specifications and statements of work (SOW) for landing gear components, evaluate vendors, and drive supplier technical execution.
• Test, Drop Qualification, and Validation: Define verification test plans, design mechanical test fixtures, support drop test campaigns, and execute functional validation against performance requirements.
• Integration and Flight Test Support: Support prototype assembly, ground taxi testing, and flight test operations to identify discrepancies, resolve mechanism anomalies via root-cause investigation, and implement rapid design changes.
This is a full-time regular employee position with bonus, benefits, and equity. The role requires Secret clearance eligibility.
REQUIREMENTS:
• Minimum 7–12 years of direct experience in aerospace mechanism design, aircraft landing gear systems, or primary structural development.
• B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or related technical discipline.
• Deep mastery of classical solid mechanics, kinematics, dynamics, fatigue, materials selection (alloys, heat treatments, surface treatments, allowables), and GD&T/tolerance stack-up methodologies.
• Demonstrated capability performing closed-form hand calculations and FEA analysis (linear, non-linear, buckling, modal) for high-load mechanism and structural components.
• Extensive experience in 3D CAD modeling, mechanism layout, and drawing release (Siemens NX preferred, or equivalent like CATIA/Creo) with PLM workflows.
• Proven track record sourcing aerospace hardware, collaborating with specialized mechanism/actuator suppliers, and supporting physical builds and test rigs.
• Demonstrated ability to self-direct, prioritize technical tasks without oversight, and deliver functional hardware under tight timelines.
• Secret clearance eligibility.
PREFERRED QUALIFICATIONS:
• Direct experience with UAV, autonomous aircraft, or rotorcraft landing systems and arresting gear integration.
• Familiarity with aerospace structural, environmental, and mechanism drop-test standards (MIL-STD-810, RTCA DO-160, AS6053, MIL-A-8866/MIL-A-8867).
• Hands-on machine shop, fabrication, or mechanical assembly experience in a prototype or rapid R&D environment.
