Spotify, NYC and Stockholm, for...lots of stuff!
- SRE
- Backend Infrastructure
- Machine Learning
- Mobile iOS and Android
- Team lead positions for most of the above
- Lots of things not-mentioned (<a href="http://www.spotify.com/se/jobs/" >http://www.spotify.com/se/jobs/</a>)
On the backend, we have an (extremely) service-oriented architecture written primarily in python and java with smatterings of C++ and others thrown in.  Storage is Postgres or Cassandra.  Messaging is zmq and protobuf and a few other interesting things.
On the frontend, we do hybrid native+CEF for most platforms.
We have (I think, anyway) a pretty interesting approach to how we work, which you can read some more about here: <a href="http://de.scribd.com/doc/113617905/Scaling-Agile-Spotify" >http://de.scribd.com/doc/113617905/Scaling-Agile-Spotify</a> and here: <a href="https://hep.cat/d/nrh-how-we-work.pdf" >https://hep.cat/d/nrh-how-we-work.pdf</a>
We're looking for experienced developers, no junior roles, sorry.
