Staff Fluid Systems Engineer

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

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

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
