Job Description:

Shield AI is pioneering the development of AI-powered autonomous aircraft for national defense, pushing the boundaries of aerospace innovation. Our next-generation UAS is a high-endurance unmanned system designed to operate in complex, contested environments where reliability, robustness, and speed to field matter.

We are seeking a Senior Staff Mechanical Test Engineer to lead and own the strategy, architecture, and execution of mechanical test systems supporting flight hardware for our next-generation UAS. This role is critical to ensuring hardware is qualified, validated, and sustained through aggressive development timelines and real-world operational conditions.

In this role, you will act as a technical authority for mechanical test and ground support systems, driving requirements, trade studies, and design decisions while mentoring engineers and partnering closely with flight, manufacturing, and operations teams.

• Own the end-to-end mechanical test strategy for flight hardware, including requirements definition, architecture, design, build, and lifecycle sustainment of test systems.

• Lead the design and development of fixed and field-deployable test stands, fixtures, and ground support equipment interfacing with aircraft structures, propulsion systems, motors, avionics, and subsystems.

• Drive structural, thermal, and fatigue analysis to validate designs for harsh military environments, transportability, and repeated use.

• Serve as the technical decision-maker for mechanical test systems, balancing performance, cost, schedule, manufacturability, and maintainability.

• Review and approve detailed CAD models, drawings, and specifications; set standards for design quality, documentation, and configuration control.

• Lead and participate in cross-functional design reviews (PDR/CDR/TRR), advocating for testability, simplicity, and rapid learning.

• Partner with suppliers and manufacturing teams to ensure scalable, cost-effective production and long-term sustainment of test hardware.

• Mentor and guide junior and mid-level engineers, setting technical direction and raising the overall quality bar of the team.

• Support flight test and field operations, including rapid troubleshooting, test system modification, and on-site integration when required.

• B.S. in Mechanical Engineering or related STEM field.

• 7–10+ years of experience designing mechanical systems for aerospace, ground support equipment, test infrastructure, or heavy industrial systems.

• Deep mastery of mechanical fundamentals, including structural mechanics, materials, dynamics, and thermal behavior.

• Expert-level proficiency in CAD tools (NX, CATIA, SolidWorks, or equivalent), including complex assemblies and released drawings.

• Strong experience with structural analysis, material selection, and manufacturing processes for ruggedized, high-reliability systems.

• Hands-on experience designing test stands, fixtures, or support equipment for aerospace or similarly demanding applications.

• Proficiency with FEA, thermal analysis, and fatigue/lifecycle testing.

• Proven ability to operate in a fast-paced, ambiguous environment, owning problems from concept through execution.

• Demonstrated history of high ownership, strong judgment, and collaborative leadership.

• Experience supporting UAS, aircraft, propulsion, or large aerospace-grade structures.

• Experience designing field-deployable or expeditionary test systems.

• Ability to rapidly prototype and manufacture designs in a machine shop or lab environment.

• Experience owning large-scale test or facilities projects from concept through deployment.

• Knowledge of hydraulics, NDE/NDT methods, and aerospace structural validation practices.

• Prior experience acting as a technical lead or subject-matter expert for test or ground systems.
