Nanny Needed For My Children - Now Hiring

We're looking for a regular afternoon sitter/part-time nanny that could help us with our two kids (ages 4 and 6) in South Slope, Brooklyn for September, with potential to trial in July. We'd expect hours to be around 2 p.m. until 6pm, primarily needing help with school/afterschool pick-up, getting the kids to after school activities if needed, light meal prep, light housekeeping/kid laundry if open to it. We'd love someone who's energetic, kind, playful, reliable, and comfortable in Park Slope/Windsor Terrace neighborhoods around the park. Bonus if Mandarin-speaking, but not necessary. Must be comfortable being paid on the books.
