Hi and welcome, and it is great that you are considering this important issue carefully.
That's the first step of responsible ownership.
My own feeling is that this would be a pretty poor quality life for the dog -- leaving him or her with only a few hours a day of actual companionship, and dogs are highly social animals. This breed in particular is very human-dependenent -- they are genetically programmed to want very close companionship and thus suffer more than many breeds if left alone.
Now that said: there are responsible owners who make the sacrifices to give a dog a reasonable quality of life despite their own work schedules. You really only could do this if you make arrangements to leave the dog every day with doggie daycare -- given this huge stretch of time, I do not think it would even be adequate to have someone come in daily midday to walk your dog and give a toilet break, which is the choice some make who would be away say 5-8 hours. But 11 hours is just a huge stretch of time and a dog could not be left outside during that time nor could it hold itself inside for all that time.
A puppy though, even if you make such arrangements, would be a very poor choice -- you would end up with a completely unhousetrained dog, with no training and little chance to bond with its actual owners.
Having a dog (or two!) is a wonderful addition to life BUT many of us are not at the right time to have them because our work keeps us from home, our commute times are too long, and/or we travel too much. You are right to recall how happy a dog that had someone around all day was and to be concerned about providing that same quality of companionship for a dog now (for after all, companionship goes two ways -- the dog needs its people around too!).
I waited until I was well into my career to get a dog though I'd have loved one a decade or more earlier. But I travelled too much, liked to be out at night socialising, etc. Only when I reached a point where I could work mostly from home, and curtailed my travelling, did I fell I could offer a dog a good life.
You are really responsible to be thinking about this now before making a lifetime commitment to a dog. A lot of people don;t and end up with mal-adjusted, problem dogs or rehoming or sending their dog to the pound. A dog is a LOT of work -- especially a puppy which really needs someone around most of the day for the first year as you shape that pup into a well adjusted well trained adult -- and needs real time commitment.
I do think you'd have a very hard time finding a responsible, health-focused breeder who would home a puppy into a situation where no one was home for 11 hours 5 days a week either, even if you did have a commitment to 5-days a week doggie daycare.
