Pros
As a Test Engineer I am exposed to almost every system of our Falcon9 rocket and Dragon capsule. I am never stuck doing only one task and I am constantly learning new things. I have experience in conducting over 25 structural and functional tests on different components and assemblies. The experience of completing these tests and watching these parts function as designed in space is the most rewarding, satisfying and exciting experience ever. At times, my job also requires design and analysis work to develop test stands for new components/assemblies. Even though this job at times can require long days at work, 12+ hours, I still find ample time to pursue my hobbies and maintain an outside of work social life. I have never had any troubles taking vacations, with durations lasting as long as two weeks. SpaceX is an extremely exciting company to work for. I do not know of any other company that is changing the way the world looks at space access.
Cons
As with any highly technical career there are, at times, extreme amounts of pressure. Even though this might be a CON, I also see it as a PRO because I feel I work well under pressure and it has helped me develop my engineering skills and ability to overcome any challenge.
