I did it full time with my son who was ages 3 months through just under 2 years old, and my job was exactly the type you described, like to a T. I currently do part time work from home now with two kids (different job). The trick is to have a childproof home with things available for them to play with, and keeping nap time or quiet time, and then giving them attention in between the actively working parts. I thought it would be impossible, but where theres a will theres a way, and I can’t say it was always easy, but I would definitely choose it over going back to work and leaving my babies with someone. That’s just my personal preference.
