Do you like packets?
Extreme Networks is hiring experienced network engineers in Utrecht, The Netherlands.  We're looking for people that have experience troubleshooting internetworking issues with any vendor(Cisco, Juniper, etc).  UNIX/Linux experience is also welcome.  We're not all that particular on skillset we just want to hire smart, motivated technology generalists.
We are a networking equipment manufacturer that makes really fast and really dense ethernet switches.  We're not a startup, but we're also not a large company.  So individual contributors can still have an impact.
Our primary product is our custom OS based on Linux that runs on our entire product line.  Your job would primarily be as a customer facing test engineer reproducing and understanding bugs in this OS and associated hardware.  You would work mostly in a lab with packet generators and switches/routers where you would simulate different network conditions and try to make things break.
Message me if you're interested.
