Propulsion Component Engineering Intern - Spring 2027
Hermeus•Los Angeles, CA
•$25 - $33•Onsite
About The Position
As a Propulsion Component Engineering Intern, you will support the development of flight-critical mechanical and fluid system components, including valves, actuators, and integrated propulsion hardware. 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. This is a Spring internship, lasting approximately 16 weeks (January - April).
Requirements
- Practical experience designing, building, and testing hardware or vehicles through internships, coursework, research, or hands-on projects
- Must 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)
- Strong interest in propulsion systems, mechanical systems, and hardware development
- Strong understanding of engineering first principles, including fluids, thermodynamics, mechanics, and materials
- Demonstrated ability to work within cross-functional teams
- Enthusiasm for aviation and Hermeus's mission
- Excellent written and verbal communication skills
- GPA of 3.0 or above
Nice To Haves
- Experience with propulsion systems, high-pressure fluid systems, or aerospace mechanisms through internships, coursework, research, or projects
- Experience designing or building components such as valves, actuators, or fluid control hardware
- Familiarity with high-temperature materials, sealing strategies, and common mechanical failure modes
- Familiarity with GD&T, tolerance stack-up, and precision assemblies
- Hands-on experience supporting hardware testing, assembly, integration, or troubleshooting
- Experience with CAD tools (NX preferred) and analysis tools (ANSYS or similar)
- Experience participating in rapid hardware development environments, including engineering competition teams, research programs, or internships
- Scripting experience (Python, MATLAB, or similar) for analysis or automation
Responsibilities
- Support the development of propulsion components (e.g., valves, actuation systems, and fluid control hardware) from concept through flight-ready delivery
- Contribute to designs for extreme environments, including high pressure, temperature, and transient operating conditions
- Support engineering trade studies across performance, manufacturability, reliability, and testability
- Assist with clean-sheet design, analysis, and integration of propulsion components
- Support hardware through rapid build–test–iterate cycles
- Participate in troubleshooting and root cause analysis during development and test
- Work with propulsion and vehicle system owners to define requirements, interfaces, and integration strategies
- Assist with system-level sizing, architecture, and design trades
- Support development testing, qualification, and acceptance of flight hardware
- Contribute to the transition from prototype to repeatable, production-ready designs
- Assist in defining operational limits and evaluating reliability and safety across all phases of use
- Apply engineering judgment and first principles to support risk-informed design decisions
- Prioritize work effectively in a fast-paced, evolving development environment
Benefits
- 5 days of sick leave and unpaid time off
- Weekly paid office lunches
- Fully stocked breakrooms
