After her son Lucas was born, Ana Villa left her job to be a stay-at-home mom. By his first birthday, she wanted to re-enter the workforce on a flexible basis but found the options were few.

"All the exciting jobs that I would filter through were full-time", Villa said. "Every time I pressed part-time, it would become like two or three."

Her situation isn't unique. Allison Robinson said many women, particularly millennials, have seen moms who work full time and moms who stay at home.

"And we are looking for a hybrid," she said. "We're looking for meaningful, challenging work that allows us to stay professionally engaged, earning income, but also more time to spend at home focusing on our family."

That's why she created The Mom Project -- a website that matches highly-skilled women with companies looking to fill part-time positions. It's how Brett Smith of Propeller Airports found Villa and brought her on board two days a week as finance director.

"I don't need somebody to sit there at their desk for eight hours a day or what have you if they can do it in two hours. It works better for her and it does work better for us," Smith said.

In addition to part-time and project-based work, the company also helps fill something it calls "maternityships" -- essentially covering for another new mom in the weeks after she gives birth.

"So when you have someone on your marketing team going out for 16 weeks, we can send in one of our professionals who has very complimentary skill sets to cover for that gap," Robinson said.

Villa said finding work through the Mom Project took away the awkwardness of having to ask for flexibility because of child care needs. And while she said having part time work helps keep her skills sharp for possible full time work in the future, for now she's happy having a foot in both worlds.

"I'm a better mom having this kind of intellectual stimulation two to three times a week."
