About the role

Staff Fluids Systems Engineer to join the Omen autonomous air vehicle program, focusing on the design, development, and qualification of fluids systems (fuel, hydraulics, thermal management, environmental control, and pneumatics) for a Group 3 tail-sitter aircraft.

Responsibilities

  • Own and drive the design, development, and qualification of fluids systems on a Group 3 autonomous air vehicle, including fuel, hydraulics, thermal management, environmental control, and pneumatic systems, from concept through low rate initial production.
  • Lead technical efforts to define system requirements, develop architectures, evaluate trade studies, and establish methodologies for analyzing, verifying, and validating fluids systems.
  • Perform system-level analysis including pressure drop, flow distribution, thermal balance, transient response, water hammer, slosh, two-phase flow, and CFD as needed to support design decisions.
  • Work in close partnership with propulsion, structures, electrical, avionics, controls, and software teams to ensure fluids systems integrate cleanly into a reliable, flexible, cost-effective vehicle.
  • Specify, source, and qualify fluids components including pumps, valves, actuators, accumulators, heat exchangers, lines, fittings, seals, filters, and tanks.
  • Spearhead design reviews, conduct hands-on rig and aircraft-level testing, visit vendors, and develop hardware test plans that validate performance across the flight envelope.
  • Define and own fuel system architecture suitable for tail-sitter operation, including center-of-gravity management, vent and pressurization design, and unusable-fuel characterization across all attitudes.
  • Support thermal management of propulsion, avionics, and payload heat loads under hover, transition, and cruise conditions.
  • Actively contribute to the enhancement of team tools, templates, processes, and standards for fluids systems engineering.
  • Cultivate a vibrant, positive, dedicated, high-energy, educational, and enjoyable community environment.
  • Balance operational needs across vehicle subsystems while optimizing for development speed, mass, manufacturability, and cost.
  • Support critical hardware demonstrations with customers as needed.
  • Travel to test sites and vendors as needed.

Qualifications

  • A minimum of 8+ years in a technical engineering role in a professional setting, with a focus on aircraft or aerospace fluids systems.
  • Strong technical knowledge in fluid mechanics, thermodynamics, heat transfer, and the design, analysis, testing, and qualification of aircraft fluids systems.
  • Deep understanding of fuel, hydraulic, thermal management, environmental control, and/or pneumatic system architectures and the trades between them.
  • Hands-on experience designing, building, and testing fluids systems hardware, including component selection, plumbing routing, and integration into a flight vehicle.
  • Experience in an immersive technical project (collegiate project teams or professional settings).
  • Strong proficiency in CAD software (any platform, but NX preferred), with specific emphasis on plumbing, routing, and complex system installations.
  • Proficiency with system-level fluids analysis tools (e.g., Flowmaster, AFT Fathom/Arrow, GT-SUITE, EASY5, Simulink/Simscape, or equivalent).
  • Working knowledge of applicable airworthiness and aerospace standards (e.g., SAE AS, MIL-STD, AS9100) for fluids components and systems.
  • BS or MS in mechanical, aerospace, or chemical engineering, or equivalent work experience.
  • Demonstrated hands-on fabrication and test skills.
  • Eligible to obtain and maintain an active U.S. security clearance
