This includes test-rigs for development, qualification, and acceptance of launch vehicle and propulsion systems as well as entire launch bases. You work hand-in-hand with Propulsion and Launch Vehicle development teams to translate their requirements into functional designs and concepts of operations. You tackle complex engineering challenges across multiple projects and phases – from concept to detail design, execution, commissioning, and handover to site owner and operator.
Your Role in Our Space Mission:
- Design fluid systems for test and launch facilities, including rocket engine test-rigs, structure pressurization test-rigs, integrated stage testing rigs, launch pads, etc.
- Perform sizing calculations and/or numerical simulations for fluid systems, including cryogenic propellants storage, conditioning, and distribution systems, high-pressure gas distribution and pressurization systems, etc.
- Select and procure suitable fluid hardware , including tanks, pumps, heat-exchangers, valves, pressure regulators, safety-valves, instrumentation, etc.
- Prepare technical documentation , such as PFDs and P&IDs, hardware lists, datasheets, etc. that serve as a basis for manufacturing planning and execution
- Lead and contribute to system design reviews and risk assessments , ensuring safety, reliability, and compliance
