As a Propulsion Test Engineer, your day usually begins with preparing and calibrating test equipment, collaborating with engineers and technicians to review test plans, and ensuring all safety protocols are in place. During tests, you'll monitor propulsion systems, collect data, and troubleshoot any technical issues that arise. After testing, you'll analyze data, present findings to project teams, and document results to support further development. The position involves a balance of hands-on work in test facilities and desk-based analysis, often requiring close collaboration with design, manufacturing, and quality assurance teams.
