About the role

Responsibilities

  • Design and develop fuel storage, transfer, and venting systems to support high-performance, long-endurance UAVs.
  • Perform fluid and thermal analysis to optimize 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.

Required 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).

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 optimization and energy management strategies.
