OtherEngineering Intern

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

~3 min read

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)

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

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

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

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

The hourly rate listed for this internship is intended as a general guideline. Final compensation will be determined based on degree level.
