Senior Mechanical Engineer, Systems Integration

About the role

Shield AI, a defense-tech company, is hiring a Senior Mechanical Engineer, Systems Integration in Seattle. You will lead the design and integration of complex aircraft systems from concept through production, owning subsystem-level integration activities such as installation design, equipment packaging, routing, interface definition and manufacturing support, while ensuring compatibility across structures, avionics, propulsion and other aircraft systems.

Key responsibilities

• Lead the mechanical integration of complete aircraft subsystems from concept through production, ensuring compatibility across structural, electrical, avionics, propulsion and manufacturing interfaces.
• Develop installation architecture, including subsystem packaging, equipment mounting and routing of electrical and fluid systems.
• Design complex machined, composite, fabricated and sheet metal assemblies.
• Develop and review installation drawings, assembly documentation and configuration baselines.
• Perform tolerance analyses, structural hand calculations and engineering trade studies.
• Coordinate integration during prototype builds, aircraft assembly and production, and mentor junior engineers in CAD modeling, GD&T and installation design.
• Coordinate suppliers and stakeholders on technical issues affecting integration, manufacturability, schedule or cost, and support technical planning and project execution.

Required profile

• Bachelor's or Master's degree in Mechanical Engineering or a related discipline.
• 5+ years of experience in aircraft, aerospace, defense, robotics or complex electromechanical system development.
• Demonstrated experience designing machined, fabricated, composite and sheet metal components and leading mechanical integration of aircraft subsystems.
• Ability to coordinate across Manufacturing, Stress, Systems, Avionics, Supply Chain and Test teams.

Required skills

• Advanced CAD with NX, SolidWorks, CATIA, Creo or equivalent.
• PLM systems such as Teamcenter, Windchill or 3DEXPERIENCE for engineering data, BOMs and drawing releases.
• Installation practices, subsystem packaging, interface management and EWIS, hydraulic, fuel, pneumatic or ECS routing.
• GD&T, ASME Y14.5, tolerance stack-up and drawing release processes.
• Experience supporting manufacturing, prototype builds, production issue resolution or MRB activity.
• Preferred: aircraft integration on UAV, military, commercial, eVTOL or autonomous programs, FEA, and experience managing technical scope, schedule, risk and supplier coordination.
