Job Description
Operating in an environment with both physical and virtual servers (Windows Servers, Linux Servers), the Systems Administrator will support the backup and recovery of an end-to-end system.
Linux semi-guru needed for 100% remote support of half a dozen servers running single instances of the LAMP stack and standard security stuff, (fail2ban, iptables, mod_security etc). Be functionally literate in PHP and MySQL, esp back-end bulk data operations, config tuning for small-to-medium loads, (up to tens of thousands of connections and rather clunky/inefficient back-ends).
Also misc dev assistance once the initial "clean-up" is done. This is in support of a distributed dev team so the supported environment will change from project to project, (dev instances plus sometimes helping customers with production instances).
Generally using newer CentOS/RHEL/Windows and there may be the occasional other distro. Minimum 5 years experience across at least a few different environments.
This position will also maintain all databases required by the system and user base. The Systems Administrator will perform daily system maintenance activities to maintain 24/7, 365 days/year system and services availability; activities include the repair, patching, fixing or replacement of existing hardware and software. The Systems Administrator will also provide Tier2 Help Desk duties for tickets escalated.
