Propulsion Component Responsible Engineer

HermeusLong Beach, CAL6 LeadSeptember 15th, 2026
Overview In this role you will own the development of flight-critical propulsion hardware from concept to flight-ready delivery, focusing on valves, actuators, and fluid control systems. You will design for extreme environments and lead rapid build–test–iterate cycles with cross-functional teams. You drive trade studies and system-level decisions to ensure reliability and safety in high-pressure, high-temperature flight conditions. This is an opportunity to shape next‑gen propulsion for high-speed aircraft and contribute to a mission with real-world impact.
