About The Role: Hermeus is seeking a hands-on Structures/Mechanical Engineering Intern to support the design, build, and test of flight hardware for next-generation aircraft systems. In this role, you will help design and develop mechanical subassemblies across the vehicle, including control surfaces, landing gear doors, avionics trays, and other flight critical hardware. This internship is ideal for students who enjoy owning real hardware, working in a fast-paced development environment, and taking designs from concept through fabrication, integration, and test. Fall: Around 16 weeks (August - December)

Responsibilities • Support the design and development of flight hardware and mechanical subassemblies for aircraft systems.

• Assist with CAD modeling, drawing creation, hardware release, and design updates.

• Perform basic hand calculations and engineering analysis to support design decisions.

• Help build, integrate, troubleshoot, and test prototype and flight hardware.

• Collaborate with structures, mechanical, manufacturing, avionics, and test teams to support vehicle development.

• Contribute to design reviews, test planning, and documentation of lessons learned.

• Support rapid iteration by identifying design improvements, simplifying hardware, and incorporating feedback from build and test activities.

Requirements: • Currently pursuing a degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, or a related technical field. (undergraduate student in your third or fourth year of study, or enrolled in a Master's or Ph.D. program).

• Strong engineering fundamentals, including statics, dynamics, mechanics of materials, and mechanical design.

• Hands-on experience with hardware through internships, research, labs, personal projects, or student teams such as FSAE, rocketry, robotics, or similar.

• Familiarity with CAD tools

• Comfortable working with physical hardware, hand tools, test equipment, and fast-paced build environments.

• Interest in aircraft structures, mechanical systems, flight hardware, and rapid hardware development.

• Strong communication skills and ability to work cross-functionally with engineering, manufacturing, and test teams.

• Strong understanding of engineering first principles.

• Enthusiasm for aviation and Hermeus's mission.

• GPA of 3.0 or above.

Preferred Skills and Experience: • Designed and released flight hardware.

• Familiarity with Siemens Teamcenter and NX.

• You’ve built something that’s flown, broken, or both.
