Senior Fluids Engineer

Responsibilities

• Design valves (flow control, isolation, regulation, check, and relief) for propellant, pressurant, and thermal fluid systems used on propulsion and launch vehicle systems.
• Develop fluid storage hardware including propellant tanks, pressure vessels, and accumulators from concept through qualification.
• Design fluid routing architecture: tubing runs, manifolds, fittings, flex lines, and quick-disconnects for vehicle integration.
• Own fluid subsystem layout and integration, ensuring compatibility across propulsion, thermal, and pneumatic systems.
• Perform hydraulic and pneumatic analysis (pressure drop, flow distribution, water hammer, thermal transients) to size components and verify system performance.
• Perform structural analysis (FEA, hand calcs) and validate with test and flight data.
• Select materials compatible with propellants, pressures, and operating environments (cryogenic, high-pressure, corrosive).
• Generate detailed component and assembly drawings, specifications, and interface control documents.
• Support and execute component-level and system-level test campaigns (proof, burst, flow, leak, cycle life).
• Work directly with manufacturing and technicians to resolve build issues, improve producibility, and support rapid iteration.
• Support vehicle integration, fill/drain operations, and ground system interfaces.
• Contribute to anomaly investigation, post-flight inspection, and design improvements for reuse and reliability.

Qualifications

• Bachelor’s degree in Mechanical, Aerospace, Chemical, or related engineering field.
• 3+ years of experience designing fluid system hardware (valves, regulators, tanks, tubing, or fittings) for flight or high-performance applications.
• Experience with fluid system analysis: pressure drop, flow sizing, structural analysis of pressure vessels, or thermal-fluid modeling.
• Hands-on experience taking hardware from design through build and test.
• Proficiency with CAD tools (NX, CATIA, or SolidWorks) for detailed part and assembly design.
