• Collect, organize, and analyze engine performance and test data
• Help prepare engines, fuel systems, cooling systems, and supporting hardware for testing
• Support troubleshooting and root-cause analysis of engine, combustion, thermal, or mechanical issues observed during testing
• Participate in test planning, test procedure documentation, and post-test reporting
• Assist with fabrication, assembly, and modification of test fixtures, plumbing, and support equipment
• Collaborate with mechanical design, controls, manufacturing, and simulation teams to improve engine performance and reliability

• Strong interest in engines, propulsion systems, thermodynamics, and experimental testing
• Basic understanding of internal combustion engines, fluid systems, heat transfer, and mechanical systems
• Hands-on experience with tools, fabrication, assembly, or laboratory work
• Ability to troubleshoot mechanical and test-related issues in a practical environment
• Strong organizational skills and attention to detail when handling data and test procedures
• U.S. person status (citizen or permanent resident) preferred due to defense/aerospace-related projects
• Ability to thrive in a fast-paced, prototype-heavy environment with rapidly changing priorities
Preferred Skills & Experience:
• Prior experience with engine dyno testing, Formula SAE, Baja SAE, motorsports, UAVs, robotics, or propulsion projects
• Familiarity with data acquisition systems, sensors, LabVIEW, CAN communication, or controls systems
