Ok great! I'm attempting to get a new job once I return from the States in early August so if I get one then, I'll apply 6 months from then in Februrary 2020.
Would this be possible to do, or do I continue to misunderstand how category A works?
If you want to get a second job to meet the income requirement, then it is much better to use Category B. I am in the exact same situation with my partner at present as they have recently just started a new second job.
For Category B, you need to be have been making over £18,600 for the past 12 months. And this can be with the combined income from 2, 3 or more jobs.
How much have you made in your present job for the past 12 months ?
If you have made for example, £18,000, then as soon as you make £600 in your new second job, you will meet the financial requirement. You will NOT need to wait 6 months. As long as you have made more than £18,600 or more for both jobs in the 12 months preceding your application, you will meet the requirement.
Let's say you get a second job in early August, and from the period September 1st 2018 to September 1st 2019 (for example) you made £18,000 from your first job. If you earn £600 or more in your second job by September 1st 2019, your partner would be able to apply as soon as September as you will have made £18,600 or more from both jobs in the 12 months preceding your application.
(ALSO . . . I'm not sure if you are aware of this, but if you and your partner have significant savings, and you have been in your first job for over 6 months, then you can use those savings to compensate if you are below the financial requirement of £18,600.
If you have made £9,000 in the past 6 months, this would equal an annual salary of £18,000. You will therefore be £600 short of the financial requirement. You would then need £16,000 in savings plus 2 and a half times the shortfall. So if you are short £600, you will need to multiply that by 2 and a half times to get £1,500. £16,000 + £1,500 = £17,500. Therefore, if you and your partner have combined savings of £17,500 or more, then you can use that to compensate for the shortfall in your salary to meet the requirement. But let's say you only made £8,500 in the past 6 months, that would be an annual salary of £17,000 and a £1,600 shortfall. That shortfall times 2 and half (£4,000) plus £16,000 would mean you would need £20,000 in savings to meet the requirement.
Additionally, these savings will need to have been held in your accounts for 6 months or more. These funds can also have been given to you as 'gifts'. So family or friends could give you this money, but it would have to have been in your accounts for 6 months or more before you could use it to compensate for the shortfall in your annual salary. You would also need to prove with original bank statements that the savings have been in your bank accounts for 6 months or more.)
This Home Office guidance provides everything in great detail. It was published August 2017, and I'm almost entirely sure it is still valid and up to date. It is very complex, but it is worth reading it fully (or at least the parts that specifically apply to your situation). You will have a perfect understanding of the rules if you can manage to figure it out. It took me a bit, but I got there myself eventually.

However, it's always better, if you can, to have sufficient leeway and for everything to be as straightforward as possible. It would always be preferable to have been in one job for 6 months and making £20,000 or more as opposed to working in 2 different jobs for the past 12 months and just scraping past £18,600. But of course, if you're in the latter situation and don't want to wait another year, than just go for it.
Make sure all your documents are in order. Have all your payslips and a letter of confirmation of employment from each employer. You will also need the corresponding original bank statements to show that all of your wages have been paid into your accounts.
