Job Description:
Shield AI is on a mission to build the world’s most advanced AI pilots for next-generation autonomous aircraft, and we’re looking for a Lead Fuel Systems Engineer to drive the design, development, and integration of cutting-edge fuel systems that push the limits of endurance and performance.
In this role, you’ll be at the forefront of developing mission-critical fuel solutions for our next generation advanced UAV platform, ensuring seamless fuel storage, transfer, and pressurization for long-endurance, high-performance autonomous flight. You’ll work alongside top-tier engineers in propulsion, avionics, structures, and AI to create game-changing fuel systems that enhance survivability, efficiency, and operational flexibility in contested environments.
This is more than just a job—it’s a chance to redefine what’s possible in autonomous aviation.
What you will do in this role:
- Lead the design and integration of advanced fuel systems for autonomous aircraft in high-stakes missions.
- Optimize mission endurance and weight distribution through innovative fuel storage, transfer, venting, and pressurization solutions.
- Architect fail-safe, redundant fuel management systems to ensure operational flexibility and survivability.
- Collaborate cross-functionally with propulsion, avionics, thermal, and structures teams for seamless system integration.
- Apply CFD and system-level modeling to optimize fuel flow, minimize pressure losses, and enhance thermal stability.
- Oversee supplier selection, component qualification, and aerospace-grade fuel system testing.
- Solve real-world challenges like cavitation, thermal expansion, and high-altitude fuel behavior.
- Support fuel system testing, troubleshooting, and performance analysis for flight validation.
- Ensure compliance with FAA, MIL-STD, and aerospace fuel system regulations.
Required qualifications:
- 8 + years of experience in aerospace fuel systems engineering, fluid mechanics, and propulsion integration.
- Deep expertise in fuel storage, transfer, pressurization, and venting systems for high-performance aircraft or UAVs.
- Strong background in fluid dynamics, thermodynamics, and computational fluid dynamics (CFD).
- Proficiency in CFD tools (ANSYS Fluent, OpenFOAM), MATLAB, Simulink, and CAD (CATIA, NX, SolidWorks).
- Experience with DO-160, MIL-STD-810, or other aerospace fuel system certification standards.
- Hands-on knowledge of fuel pumps, valves, sensors, and system integration testing.
- Strong troubleshooting and problem-solving skills for prototype and production fuel systems.
- US Citizenship required due to security clearance requirements.
Preferred qualifications:
- Experience with military UAVs, fighter jets, or high-endurance ISR platforms.
- Background in stealth fuel system design and vapor management.
- Knowledge of alternative fuel technologies, hybrid-electric propulsion, and advanced energy storage.
- Experience supporting flight test operations and mission endurance optimization.
