San Francisco, CA and Toronto - PagerDuty (YC '10)
At PagerDuty, we are building an alerting and incident tracking system to help IT operations groups detect and respond to issues. Startups, Fortune 500 companies, and everything in-between rely on us to alert them quickly when they have operational troubles.  We've got interesting technical problems in spades, just closed our Series B, and are still very much a startup.  We're hiring for pretty much everything, technical and non-technical alike.
We don't hire based on experience with a handful of tools. Instead, we want smart, capable, and experienced people who can learn our tools quickly (and suggest new ones!) as needed.  Experience with our stack is just a bonus.
