You will contribute to hardware development from clean-sheet design through build, test, qualification, and production, working closely with propulsion and vehicle teams. Your work will directly support systems operating in high-pressure, high-temperature, and dynamic flight environments.\nSpring: Around 16 weeks (January - April)\nResponsibilities:\nSupport the development of propulsion components (e.g., valves, actuation systems, and fluid control hardware) from concept through flight-ready delivery\nContribute to designs for extreme environments, including high pressure, temperature, and transient operating conditions\nSupport engineering trade studies across performance, manufacturability, reliability, and testability\nAssist with clean-sheet design, analysis, and integration of propulsion components\nSupport hardware through rapid build-test-iterate cycles\nParticipate in troubleshooting and root cause analysis during development and test\nWork with propulsion and vehicle system owners to define requirements, interfaces, and integration strategies\nAssist with system-level sizing, architecture, and design trades\nSupport development testing, qualification, and acceptance of flight hardware\nContribute to the transition from prototype to repeatable, production-ready designs\nAssist in defining operational limits and evaluating reliability and safety across all phases of use\nApply engineering judgment and first principles to support risk-informed design decisions\nPrioritize work effectively in a fast-paced, evolving development environment\nRequirements:\nPractical experience designing, building, and testing hardware or vehicles through internships, coursework, research, or hands-on projects\nMust be currently enrolled in a STEM program at an accredited college or university (undergraduate student in your third or fourth year of study, or enrolled in a Master's or Ph.D. program)\nStrong interest in propulsion systems, mechanical systems, and hardware development\nStrong understanding of engineering first principles, including fluids, thermodynamics, mechanics, and materials\nDemonstrated ability to work within cross-functional teams\nEnthusiasm for aviation and Hermeus's mission\nExcellent written and verbal communication skills\nGPA of 3.0 or above\nPreferred Skills and Qualifications:\nExperience with propulsion systems, high-pressure fluid systems, or aerospace mechanisms through internships, coursework, research, or projects\nExperience designing or building components such as valves, actuators, or fluid control hardware\nFamiliarity with high-temperature materials, sealing strategies, and common mechanical failure modes\nFamiliarity with GD&T, tolerance stack-up, and precision assemblies\nHands-on experience supporting hardware testing, assembly, integration, or troubleshooting\nExperience with CAD tools (NX preferred) and analysis tools (ANSYS or similar)\nExperience participating in rapid hardware development environments, including engineering competition teams, research programs, or internships\nScripting experience (Python, MATLAB, or similar) for analysis or automation\nAdditional Requirements:\nWillingness to work hands-on in build, integration, and test environments\nAbility to support extended hours during critical test campaigns\nWillingness to travel to support hardware builds and flight tests\nMust be eligible to access export-controlled
