## Description

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems.

As a Senior Systems Integration Engineer, you will lead the design and integration of complex aircraft systems from concept through production. You will own subsystem-level integration activities, including installation design, equipment packaging, routing, interface definition, and manufacturing support, while ensuring compatibility across structures, avionics, propulsion, and other aircraft systems.

## 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 for complex aircraft systems, including subsystem packaging, equipment mounting, and routing of electrical and fluid systems.

- Lead the design of complex machined, composite, fabricated, and sheet metal assemblies requiring advanced engineering judgment.

- Develop and review installation drawings, assembly documentation, and configuration baselines to ensure design consistency and production readiness.

- Perform advanced tolerance analyses, structural hand calculations, and engineering trade studies supporting design decisions.

- Coordinate subsystem integration activities during prototype builds, aircraft assembly, and production.

- Mentor junior engineers in CAD modeling, GD&T application, installation design, and engineering best practices.

- Coordinate suppliers and internal stakeholders to resolve technical issues affecting integration, manufacturability, schedule, or cost.

- Support technical planning, schedule development, and project execution for assigned work packages.

## Required Qualifications

- Bachelor's or Master's degree in Mechanical Engineering or 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 from concept through production release.

- Demonstrated experience leading mechanical integration of aircraft subsystems or complex assemblies.

- Advanced CAD proficiency with NX, SolidWorks, CATIA, Creo, or equivalent.

- Experience managing engineering data, product structures, Bills of Material (BOMs), and drawing releases using PLM systems such as Teamcenter, Windchill, or 3DEXPERIENCE.

- Working knowledge of aircraft installation practices, subsystem packaging, interface management, equipment mounting, and maintainability considerations.

- Experience developing installation layouts and routing solutions for EWIS, hydraulic, fuel, pneumatic, ECS, or similar mechanical systems.

- Experience developing part drawings, assembly drawings, and installation drawings.

- Working knowledge of EWIS, hydraulic, fuel, pneumatic, or ECS routing design.

- Strong knowledge of GD&T, ASME Y14.5, tolerance stack-up, and drawing release processes.

- Experience supporting manufacturing, prototype builds, production issue resolution, or MRB activity.

- Ability to coordinate across Manufacturing, Stress, Systems, Avionics, Supply Chain, and Test teams.

## Preferred Qualifications

- Aircraft integration experience on UAV, military, commercial, eVTOL, or autonomous aircraft programs.

- Experience performing structural hand calculations, margin assessments, or preliminary stress analysis.

- Experience with FEA including static, modal, vibration, fatigue, or thermal analysis.

- Hands-on experience supporting build, production, testing, or hardware validation activities.

- Experience managing technical scope, schedule, risk, or supplier coordination for subsystem work packages.

- Familiarity with aircraft-level requirements, interface control, and configuration management.
