3+ years of hands-on experience designing, qualifying, or owning fluid components (valves, regulators, filters, burst disks, manifolds, transducers) for spacecraft, launch vehicles, or comparable high-pressure hardware, on either the vehicle or the component-supplier side (typically 6+ years for Principal). The component portfolio spans each of these fluid subsystems and includes solenoid control valves, check valves, relief valves, burst disks, fluid filters, regulators, manually operated service valves, machined fluid manifolds, and instrumentation including pressure transducers and RTDs.
