Systems Administrator
Job ID: 21565
Division: Physical Biosciences
Date Opened: 3/23/2008

Summary: The Joint BioEnergy Institute (JBEI) is seeking a Computer Systems Administrator to be a part of the Technology Division. The scope of this position includes managing research and administrative computing resources, especially linux servers and Apple/Windows desktops, and making project and public data accessible in a timely manner to project participants, and integrating the data with existing data from other databases.

Duties: Plan, organize, prioritize and complete assigned tasks and projects in a timely manner. Frequently and clearly communicate task or project status to customers to either set or negotiate expectations. Under the broad supervision of the Vice President of Technology and the Computational Analysis Director: 50% - Provide linux system administration and user support for research groups. This includes system installations, software installations from packages or from source code, distribution upgrades, OS and security patches, system monitoring, disk and file system management, system hardware and peripheral management, backup and recovery management, troubleshooting, and crash recovery. Configure, administer, and troubleshoot various web servers and other services and daemons. Participate in the formulation, planning, organizing, implementation and support of new services or capabilities. 40% - Provide desktop and laptop support, for both Apple and Windows systems. This includes system installations, software installations from packages or from source code, distribution upgrades, OS and security patches, system monitoring, disk and file system management, system hardware and peripheral management, backup and recovery management, troubleshooting, and crash recovery. 10% - Assist researchers with program compilation, commercial and public domain software installation, and use of UNIX tools and utilities.

Qualifications: At least five years linux system administration experience, with responsibility for a wide range of hardware and distributions. Specific areas of required experience include Apache; Python/Perl; bash/tcsh, including writing complex Bourne shell scripts; runlevel 1 for critical update or recovery purposes; remote administration, including ssh, remote serial consoles, and remote PDUs; NFS; LDAP, primarily the OpenLDAP server and clients and RAID controllers. Firm understanding of linux internals including the boot process, kernel versions, and recovery scenarios. Familiarity with sendmail and with email protocols in general. Experience developing applications in Python/Perl and developing Web-based applications using CGI. Experience with a code management system, preferably SVN or CVS, as both administrator and code contributor. Demonstrated ability to incorporate disparate protocols to provide services to researchers and collaborators. Experience with relational database operation and maintenance, specifically with MySQL, PostgreSQL or Oracle. Database experience should include database design, implementation, installation, and administration, including backup and restore of large databases. Experience performing administration tasks for commodity desktop and laptop systems, running the Mac OSX and/or Windows operating systems; including OS installation, OS upgrading, system recovery, user account administration, third party software installation, and debugging network problems. Ability to employ a flexible approach to solving software problems, and to balance independent approaches to software issues, with specifications developed by others, including project management, project researchers, and other software developers. Demonstrated ability to make progress on multiple tasks simultaneously, and to work both independently and as a member of a team. Must be available as needed nights and weekends for critical system updates that cannot be performed during regular lab hours.

NOTE: This is a one year Term appointment with the possibility of renewal under the same terms and conditions, contingent upon continued funding and availability of work.
