Have you used MongoDB in a serious way? We found it great to develop with, but now it's scaling up, we need a MongoDB expert to ensure it runs fast and reliably.
Can you administer a server farm of linux boxes? Serving big websites, but also processing data on a large scale?
If so, this is the job for you. We have a very interesting project. You'll be working with top people who know what they're doing but also wise enough to know what they don't know.
Not necessary for the job, but Python programming skills will also come in handy.
You must be:
* Pragmatic: you will choose the right technologies and level of thoroughness relative to the business problem.
* Good at English.
* Available to fix things on call (but of course you have the skills to building stable systems so, that won't happen very often)
* Available to answer questions quickly.
* Scientific - able to calculate performance as things scale up massively.
