An aeronautical engineer works with aircraft and their propulsion systems. As an aeronautical engineer, your job is to design, develop, and implement new procedures and technologies for the creation and maintenance of aircraft components. Specific duties involve testing new designs and materials, assessing parts that were damaged or malfunctioned during flight, and collaborating with designers, pilots, and other engineers. You play an essential role in the aircraft manufacturing process. Aeronautical engineer positions are typically available with aircraft and aerospace manufacturers, government agencies, defense contractors, and aerospace engineering firms.
