I would like to offer a frame challenge:
Why should she get a job? Does she actually need one? Why does she need a job?
There are a lot of people who are willing to live extremely cheaply. Some of these people do not need a job. For someone who is willing to put in the effort, it is possible to feed their self for dozens or hundreds of dollars per year. Personally, I like to buy cheap food in bulk, the best being food that costs less than a half-dollar per pound, and I have augmented that with a vegetable garden. Where I live, water is literally cheaper than dirt; if I recall correctly, I pay less than a penny per gallon of water.
If she does not need the money, why bother to waste her time acquiring it? If she does not live cheaply and expects you to pay for everything, then next time she wants something tell her you are willing to help her get it by paying for half of it for her.
However, even if she does not live cheap and expects you to pay for everything, that does not mean there is no value added. My wife has not had an income-generating job in years. We both still consider her to have a job though, just a job at home. Her activities at home, such as managing our supplies, cooking, finding good sales on things, ect., saves us a reasonable amount of money. A dollar saved is a dollar earned. Since you are looking at your relationship financially, you should take into account the value added as well as the finances consumed by her.
In our case, we have children too. Child care is very expensive here, and we do not trust the child care services anyway because there are too many reports (some confirmed) of child abuse at them. The non-financial benefits of caring for your own children are even more pronounced.
Adding child care savings to the already mentioned general savings means that my wife probably saves us more money than she would make if she got a minimum wage job, so she practically does make as much money as if she had such a job even though she earns no paycheck.
In your case, though you may not have children, you should consider the child care savings as well if you think you might have children in the future.
If finances are one of your big worries for your relationship, then think about whether the value added by your relationship with her (financial and otherwise) is worth the financial cost.
Frame challenge answers should also provide a literal answer to the question as asked, if possible, so here it is...
There is a problem with sending out applications on her behalf if she does not even know it is happening. That would be awkward to be hit with "Surprise! We want to interview you on Friday," especially when you were not looking for a job and may not have wanted one.
What you could do is talk to her about a job opening you have seen. "Hey, I saw a help wanted ad for that one place downtown." She might not do much about it, but then later you could say "Hey, I thought I'd help you by preparing this application for you. Can I send it to them?"
