-- Warren Petrofsky
Senior Director
SAS Computing - University of Pennsylvania

The Information Security & Unix Systems (ISUS) group at the School of
Arts and Sciences (SAS) is seeking senior linux systems administrator
who is ready to change the world, one python script at a time. Become a
part of our team and work collaboratively with world-renowned
researchers who work to solve questions about the human brain, the
formation of galaxies, ocean biogeochemistry, the impact of social
programs, and more. Help us keep all of our enterprise systems ticking,
including email gateways serving more than 20,000 users. Build clusters
on campus, in Amazon EC2, and make use of the XSEDE grid to enable
research at an unprecedented scale.

Serve as lead systems administrator on highly complex linux systems
including enterprise email, database, application, and web servers. The
successful candidate will design, quote, benchmark, buy, implement and
maintain high-performance computing clusters for research groups
throughout SAS. Zealously pursue fast and collaborative solutions to
tickets/requests, partnering with both faculty and local computing
support providers throughout the school.

The systems that our group manages often represent investments of more
than $100k of grant funding for very high-profile projects. Design,
price, and administer high performance computing systems using cloud and
grid systems including Amazon’s AWS and XSEDE, and will work directly
with researchers to understand how HPC can enable and reshape their work.

We are at a critical tipping point in computing architecture. In many
cases, cloud-based infrastructure is cheaper, easier to maintain, more
reliable, and more scalable than physical hardware. Be on the SAS team
that develops and builds out our tools for deploying and managing
cloud-based service and research clusters.

Work related tasks include: performing linux systems programming and
application programming projects as needed; supporting web servers;
providing software installation and backups; coordinating hardware
repairs; coordinating ordering & installation of equipment; recommending
and tracking software & hardware; installing upgrades; handling
security; performing technical consulting & end user linux support; and
responding to and assisting first-tier support staff who assist
end-users with our systems. This position also participates in the ISUS
on-call rotation.

Bachelor’s Degree and at least 3 years of experience or an equivalent
combination of education and experience required.

The successful candidate has advanced linux systems programming skills,
and confidence with cluster queueing systems. They work collaboratively
with faculty, graduate students, research staff, and their SAS Computing
colleagues. They are passionate about the research and academic mission
of SAS; they are ready to make a difference through teamwork, ingenuity,
and the power of open source.

They can manage and track a large number of ongoing projects
simultaneously, working with their teammates to triage problems and
execute solutions. Experience with AWS EC2, XSEDE, Sun Grid Engine,
Matlab, and Drupal is greatly preferred.
