house I worked ft until recently, and so did my dh. I got home around 6.30pm usually, though occasionally snuck out to pick the kids up and do things with them. They went to bed at around 8.30pm, and prob would have gone earlier had I not been working.
I'm looking for a new job now - we moved to a different country 6 months ago and I've been at home since. The boys are now 8, 5 and 3 and all at the same school all day for the first time, so logistically speaking it would be much easier for me and dh to both work ft now than ever before. I don't like being sahm anyway and enjoy my career.
I think you will have no problem with peace of mind as your dh will be the main carer. I was always afraid that something would go wrong with my complicated childcare arrangements, creche pick-ups etc, and that was very stressful. This for me is the main thing, so you can relax about that.
Something that I think is very helpful in terms of your feeling that you are giving your kids enough attention is having one afternoon per week when you come home early. After you have got a job it's a good idea to see whether there's scope for that, for example by going in 30 mins earlier in the mornings so you can pick them up from school on Wednesdays or whatever. I never had that regularity in my job, but I more or less managed to do an afternoon with the boys once per week and that was nice for me and them.
The other thing is to make sure everything's smooth with your dh by discussing all of your little concerns. It's awful to have a row because your feeling annoyed that he lets them put sugar on their frosties or whatever!
hth! Good luck - it sounds like you're making a sensible decision.
