Sr Development Test Engineer Verified today
The Opportunity
This role is focused on development test ownership across fluid systems, instrumentation, DAQ, test stand design and 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. You own 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 and 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.
Compensation
The pay range for this role is $140,000 to $180,000 per year.
Salary and Benefits
We are competitive in compensation and offer equity as part of the package. Benefits include health, vision, dental, and 401K. We provide lunch and snacks.
