Job Description:

Shield AI builds AI pilots to enable teams of intelligent aircraft to operate in high-threat environments. As a Staff Propulsion Fluid Systems Engineer on the Group 5 UAV program, you will be responsible for the design, integration, and validation of flight-critical fluid systems supporting our advanced turbine propulsion architecture.

You’ll take ownership of high-performance fuel, air, and cooling circuits from flow path definition and component selection to system-level validation and integration. This is a fast-paced, hands-on role working with propulsion, thermal, and mechanical teams to deliver flight-ready hardware that supports long-endurance, jet-powered autonomous flight.

• Design and develop fluid subsystems for propulsion support, including fuel routing, pressure regulation, air induction, and thermal transport

• Define flow path architecture, select and spec key components (pumps, valves, fittings, sensors), and build system-level performance models

• Simulate and analyze fluid behavior under varying flight conditions using Thermal Desktop, MATLAB/Simulink, and/or ANSYS Fluent

• Collaborate with propulsion, thermal, and mechanical engineers to integrate fluid systems into tight packaging constraints

• Develop test plans and instrumentation strategies to validate fluid system behavior and performance

• Support the build and operation of test articles, ground-based propulsion setups, and subsystem evaluations

• Contribute to engineering documentation, including block diagrams, interface definitions, and hazard analyses

• Participate in design reviews and advocate for best practices in fluid architecture and component placement

• Assist with vendor coordination and prototype procurement for valves, lines, and subsystem components

• Support flight test teams in instrumentation placement, pre-flight inspection, and post-flight data analysis

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or related field

• 8+ years of experience working with aerospace fluid systems, fuel circuits, or propulsion-adjacent subsystems

• Hands-on experience with the design, integration, and testing of high-reliability fluid systems

• Strong working knowledge of fluid system design fundamentals: pressure drop, cavitation, flow regime transitions, thermal effects

• Proficiency in modeling and simulation tools: Thermal Desktop, ANSYS Fluent, MATLAB/Simulink, or similar

• Familiarity with CAD-based collaboration (Creo/NX/Inventor) and flight hardware tolerancing

• Excellent communication and documentation skills; thrives in collaborative, cross-functional environments

• Experience supporting jet propulsion or hybrid-electric systems in aerospace or defense

• Familiarity with aerospace fittings, MIL-SPEC components, and thermal insulation strategies

• Exposure to fuel slosh, altitude effects on pressurization, or cryogenic fluids

• Background in flight test support or prototype-level validation
