I'm working in EMC XtremIO, we do a high-performance enterprise storage which is a hit in the All-Flash-Array world. We do it in C and it's a game-changer in the enterprise storage world. EMC has essentially stopped saying the VMAX is a performance tier because of us, we kicked the VMAX out of the performance pool.

Lots and lots of interesting problems to work on. See http://israel.emc.com/corporate/jobs/coe/job-offerings/xtrem... for available positions and shoot me an email if interested (email in profile).
