Our client is developing a new medium-lift launch vehicle and is looking for a Test Stand Design Engineer to help build the infrastructure required to test a 700 kN-class liquid rocket engine.

This is a hands-on role covering the design, build, commissioning, and operation of propulsion test facilities.

What You’ll Be Doing

• Designing and building rocket engine test stands and ground infrastructure.
• Developing high-pressure and cryogenic propellant systems.
• Designing thrust structures, engine mounts, and mechanical hardware.
• Creating P&IDs and integrating instrumentation, controls, and safety systems.
• Leading commissioning, cold-flow testing, and hot-fire operations.

What You’ll Bring

• 5+ years of mechanical, fluid systems, propulsion, or test engineering experience.
• Degree in Mechanical, Aerospace, or a related engineering discipline.
• Experience designing high-pressure and cryogenic fluid systems.
• Strong CAD, P&ID, and mechanical design capabilities.
• Knowledge of valves, regulators, relief devices, and fluid-system sizing.
• Experience with instrumentation, structural loads, and test systems.
• Hands-on experience with commissioning, pressure testing, leak testing, and troubleshooting.

Nice to Have

• Experience with liquid rocket engine hot-fire testing.
• Knowledge of LOX and liquid methane (LCH4) systems.
• Experience with Ground Support Equipment (GSE) and propellant feed systems.
• Familiarity with LabVIEW, PLCs, or FPGAs.
• Experience with hazard analysis and high-energy test operations.
