Sr Development Test Engineer

The Opportunity 

This role is focused on development test ownership across fluid systems, instrumentation, DAQ, test stand design/build, hazardous operations, live test execution, troubleshooting, and post-test analysis.

You will design, build, and operate development test stands for propulsion and fluid systems — from initial concept through first test. That means owning the hardware end-to-end: P&ID development, component selection, tube routing and fabrication, panel layout, wiring harness installation, DAQ configuration, and checkout. You won't hand off to a separate fab team. You build it, you stand it up, you run it.

How You'll Fulfill Your Mission

• Design and build test infrastructure for propulsion, fluids, and mechanical systems, including pressurization circuits, propellant loading and drain systems, flow stands, and proof/leak test rigs.
• Develop and own P&IDs from scratch.
• Select valves, pressure transducers, flow meters, relief devices, and structural hardware.
• Fabricate, fit, and assemble fluid system hardware.
• Troubleshoot and repair under pressure during active test campaigns.
• Write, review, and execute test procedures for hazardous operations including cryogenics, high-pressure gas, and flammable propellants.
• Commission new test stands from cold iron to first ignition.
• Support test operations as console operator, test conductor, or stand crew.

Why We Value You

• 5+ years of hands-on experience in test engineering, propulsion, or aerospace GSE.
• Demonstrated ability to take a test stand from blank paper to operating hardware.
• Direct experience with high-pressure fluid systems, cryogenics, or propellant handling.
• Comfortable working in a hazardous operations environment and holding others to procedural rigor.
• Proficient with DAQ hardware (NI, Beckhoff, or equivalent) and comfortable writing basic sequences or scripts for data acquisition.
• Tube fabrication and fitting experience a plus. Able to read and mark up mechanical drawings.
• Take ownership of work from first sketch to final test report.

The pay range for this role is: $140,000 - $180,000 per year
