I've served multiple times at SheTech (an event where we invite thousands of highschool girls to come learn about tech and jobs), and I've helped host at least five Hour of Code events at Adobe where we make sure half of those invited are female where we teach robotics. I've also spent a couple years teaching refugees how to code, and we make sure half of those students are female, as well.

I've never attended personally, but we also host an event yearly called "Girls Who Code."

Adobe has also partnered with a local dev bootcamp to hire intern graduates-- I can't say for sure, but I'm pretty confident that there's an emphasis on female graduates.
