37signals is looking to hire a second system administrator to help manage our growing infrastructure. We are looking for someone who has solid experience running production web applications and good all around system administration skills. In particular, you should have strong experience with Apache, MySQL and the HTTP protocol. Some of the other software we rely on includes HAproxy, Mongrel, memcached, and Xen primarily running on RedHat Enterprise Linux or CentOS 5, with a handful of FreeBSD machines.
Experience with Cisco hardware and Ruby programming are a big plus, but attitude and enthusiasm are an even bigger one.
