Propulsion Component Engineering Intern - Spring 2027

• 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
• 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
