Propulsion Component Engineering Intern - Spring 2027

Los AngelesOn-siteInternship

AI Summary

Supports the development of flight-critical propulsion components such as valves, actuators, and fluid control hardware, contributing to design, analysis, testing, and qualification for high-pressure, high-temperature flight environments.

About this role

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About The Role:

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.
Spring: Around 16 weeks (January - April)

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 environmen

    • 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

    • Preferred Skills and Qualifications:

  • 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

    • Additional Requirements:

  • Willingness to work hands-on in build, integration, and test environments
  • Ability to support extended hours during critical test campaigns
  • Willingness to travel to support hardware builds and flight tests
  • Must be eligible to access export-controlled information
