Network Security Engineer

San Francisco, United States

About the Job

You are good at what you do, like it, and know UNIX (ideally Linux) well. You've mastered your current environment and everything is rock solid- it's time for your next challenge.

Here's what we have to work with: Per month: 5 billion page views, 20+ million visitors, 3 petabytes downloaded. Per second: 30,000 dynamic content requests, 20,000 static content requests, 25,000 DB requests and 1M+ memcached requests. Infrastructure: 650+ co-located servers, 850+ VMs, 15 SAN/NAS devices. Page builds often touch 100 machines and average response time is 75 milliseconds. We have a 3 petabyte Hadoop cluster running on 31 nodes with 20 cores each.

This is an amazing opportunity for someone who has experience working with SAN and NAS devices and is interested in setting them up to be reliable, stable, and cost-effective. You'll share accountability for guaranteeing uptime -and the pager, approximately one week out of every quarter. Occasional off hour calls are going to happen, but it's your job to engineer to minimize outages in the first place.


"We work in a fast-paced, big-impact, collaborative environment. We ship to production multiple times a day, so if you commit code now it'll be live to millions of users the very next day, or possibly later the same day!"
