Awesome job for manny or nanny for 9 year old super athletic boy

We are looking for a wonderful nanny who is happy and easy going to work with a divorced couple who have one school-aged child.  .  You go between homes.  You won’t be overworked, but due to the nature of Mom and Dad’s work — you must be flexible and available.    The child goes between the two houses every three days, so the schedule revolves.  It’s a crazy busy job but you won’t be used 24/7.  WE placed the last nanny who stayed 2 years, and has moved in to another position at the house.  This is a good and loyal family.   There could be overnights and travel. We would love someone with education and child development background.
