Here is a good place :) If you have any question I'll be happy to answer them publicly - this way it can also help others. If it's something private, you can write to me (xavier@opencraft.com).
I guess one of my first questions would be would you be open to folks who are less senior but just want to contribute to your team using Python and Django and who are willing to be a sponge to learn as much as possible to become better developers?
We sometimes take slightly more junior profiles, but it's usually very demanding on the person joining. The level of quality and efficiency required by the projects is high, so those who succeeded were the ones able to ramp up their skills quickly, and ready to invest the necessary effort. Generally, it might be an easier approach to gain experience on other projects first, and then join -- but if you are up for a challenge, you're still welcome to apply :)
