You use the word "currently" to tell how something is now, but also to suggest that it was different in the past or will change in the future. In the example above, when the speaker says that she's "currently" an accountant it means that she might get a different job soon.
You can put "currently" in a few different places in a sentence:
I'm currently an accountant at a commercial real estate company.
I'm an accountant at a commercial real estate company, currently.
But the first example at the top is the best for suggesting that the speaker's job might change.
"Currently" is a little formal and can be used in writing or in spoken English.
