This position is ideal for a mechanical or aerospace engineer with a passion for cutting-edge aircraft design, multi-disciplinary systems integration, and iterative prototyping in a fast-paced defense technology environment.

Responsibilities:

Assist in the conceptual and preliminary design of Shield AI's UAV platforms, ensuring optimal aerodynamic and structural configurations. Support aircraft sizing, weight estimation, and trade studies to evaluate different airframe configurations. Work with multi-disciplinary engineering teams (mechanical, electrical, propulsion, avionics) to ensure seamless system integration. Develop and refine 3D CAD models of aircraft structures, subsystems, and flight-critical components. Perform basic aerodynamic and structural analysis using computational tools to assess feasibility and performance impacts. Participate in design reviews, system trade studies, and prototype development efforts. Support rapid prototyping and wind tunnel testing of scaled models to validate design concepts. Assist in requirements development, documentation, and verification planning for aircraft subsystems. Ensure designs comply with manufacturing feasibility, mission requirements, and aerospace industry standards. Work closely with manufacturing and production teams to transition designs from concept to prototype and full-scale production.

Required qualifications:

Bachelor's degree in Aerospace, Mechanical, or Systems Engineering (or related field). 5 years of experience in aircraft design, configuration layout, or airframe integration. Proficiency in CAD modeling (NX, SolidWorks, or similar) for airframe and structural design. Basic understanding of aircraft aerodynamics, structures, and propulsion system integration. Ability to perform basic FEA, CFD, or weight & balance assessments. Strong problem-solving skills, attention to detail, and ability to work in cross-functional teams. Excellent communication and technical documentation skills. Active Secret clearance

Preferred qualifications:

Master's degree in Aerospace, Mechanical, or Systems Engineering (or related field). Experience with unmanned aerial vehicle (UAV) design or aircraft conceptual design. Familiarity with aircraft performance modeling, stability & control, and flight dynamics. Hands-on experience with rapid prototyping, wind tunnel testing, or flight hardware development. Knowledge of manufacturing techniques, composite materials, and aerospace structural design principles. Experience working in a fast-paced, high-tech startup or defense environment. Active TS clearance or ability to gain a TS clearance.

This role is ideal for an engineer eager to take ownership of complex subsystems, collaborate across disciplines, and grow into a technical leader working at the intersection of autonomy, flight science, and fluid systems.

Responsibilities:

• Design and develop fuel storage, transfer, and venting systems to support high-performance, long-endurance UAVs.
• Perform fluid and thermal analysis to optimise flow efficiency, pressure regulation, and system mass.
• Support integration of fuel systems with propulsion, avionics, and thermal management teams.
• Conduct CFD simulations, bench-level testing, and validation of pumps, valves, sensors, and tanks.
• Generate design documentation, system schematics, and verification plans to support engineering reviews and flight test readiness.
• Assist in supplier coordination, component selection, and qualification testing.
• Troubleshoot fuel system issues during prototype builds and flight test campaigns.
• Contribute to the development of system architecture and help mature design standards across new programs.

Qualifications:

• B.S. or M.S. in Aerospace, Mechanical, or related engineering discipline.
• 4–7 years of experience in fuel or fluid systems design, analysis, or integration.
• Working knowledge of CFD and thermal/fluid simulation tools (ANSYS Fluent, OpenFOAM, MATLAB/Simulink).
• Experience with pumps, valves, and sensors for fuel or hydraulic systems.
• Familiarity with aerospace environmental and certification standards (e.g., DO-160, MIL-STD-810).
• Excellent communication and collaboration skills in fast-paced, cross-functional environments.
• U.S. Citizenship required.

Preferred Qualifications:

• Experience supporting UAV, fighter, or propulsion system integration.
• Hands-on experience with prototype build, test, and troubleshooting.
• Familiarity with CATIA, NX, or SolidWorks for CAD design and modeling.
• Exposure to mission endurance optimisation and energy management strategies.
