Could you please proofread my career objectives?

Dear friends would you be kind enought to proofread and correct my mistakes especially the tenses and the articles?
There are two questions: why exactly work in the field? why exactly Baker Hughes?
So this is the way I answered the questions:

CAREER OBJECTIVES
There are several reasons why I would like to work in the field at Baker Hughes:
1) First of all, aside from the fact that Baker Hughes is a world-leading company, there are plenty of opportunities the company offers such as continued career growth, work in an international environment with leading edge technology and competitive salary, not to mention benefits provided to its employees such as health insurance, paid vacations, educational assistance and others.
2) Secondly, I find work in the field very interesting and challenging. While working in the field, you always learn new things, never get bored, you have to deal with different techical issues and with people from all over the world, so every day there turns out to be a learning day.
3) Thirdly, While writing degree thesis about and working on the drilling rig, I became better acquainted with the rig equipment (AC/DC motors, frequency converters, diesel generators, pumps, compressors etc.) and learned how to perform maintenance and service on it. So I would like to contribute my knowledge and experience to Baker Hughes and continue developing professional skills in the company.
4) Fourthly, work in the field is a good career opportunity because in time it'll be possible to take up a leadership position within the company and lead a team of highly trained professionals to achieve mutual goals.
