I am a structural analyst for a large aerospace company – the job is great – very interesting, always learning and developing new methodologies, testing stuff until it breaks, influencing designs etc. There is only 2 of us as well, which means there is a lot of work.
I have been doing it for 7 years now and can't imaging doing anything else or working anywhere else as the level of responsibility and the other guys I work with are great.
Also – the buck kind of stops with us on just about any component we design – so I get to feel all important which is good for the ego! Telling someone their design is a load of pish can be difficult when a deadline is 1 day away. However, as a specialist we are quite well respected – although the pay in this particular company is mediocre. I could earn 25% more elsewhere.
