No, not where I work for once, but a friend of mine is looking for an HPC sysadmin in his group in the Victoria State Government:
This role requires advanced skills in system and network administration and scripting, clustered computer systems, security, virtualisation and Petabyte-scale storage. It is highly desirable that you have acquired these skills in a Life sciences environment. The heterogeneous environment requires both Linux and Windows skills. You should have the ability to design and implement solutions for automated transfer of data within and between systems and to ensure the security of both internal and Internet-facing systems. In this complex environment, working closely in teams of multi-disciplinary scientists to deliver computing solutions, including advanced troubleshooting and diagnostic skills, will be required. Supervision of other members of the team will also be necessary.
They’ve got a 1500+ core Linux cluster..
