Job summary

Cowboy Space Corp. is seeking a fluids systems engineer to design and develop propulsion, fluids, and thermal management hardware for space launch vehicles.

You will own components from concept through qualification and flight, ensuring performance, mass, and reliability in demanding environments. Responsibilities include designing valves, tanks, tubing, and routing for integration; performing hydraulic/pneumatic and structural analyses; generating drawings and interfaces; supporting test

Qualifications

• Bachelor’s degree in Mechanical, Aerospace, Chemical, or related engineering field.
• 3+ years designing fluid system hardware 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.
• CAD tools proficiency: NX, CATIA, or SolidWorks.

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 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.
• 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 with manufacturing to resolve build issues 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.
