Valves Assembly & Testing Engineer

Job description

Valves Assembly & Testing Engineer is responsible for precision assembly, calibration, and qualification testing of cryogenic and other liquid-propulsion valves used in rocket engines and ground-support systems. This role requires deep understanding of cryogenic fluids (LOX, LHe, LCH4), high-pressure systems, aerospace materials, and stringent quality and safety standards. The engineer ensures that each valve meets mission-critical requirements for reliability, leak-tightness, and performance under extreme conditions.
