The Center for Advanced Computing Research (CACR) in the Division of Engineering and Applied Science at the California Institute of Technology has an opening for a System/Operations Administrator. CACR is Caltech’s primary center for computational science and we work across the Institute to infuse computational methods into research in science and engineering. The successful candidate will join CACR’s Operations group and report to the Manager of Operations.

Job Duties

• Support of heterogeneous computing environment, including (but not limited to):
• Installation and maintenance of OS and middleware software.
• Interaction with CACR staff, researchers, facilities personnel, and vendors to provide technical and user support.
• Assisting in the planning and implementation of facilities improvements.
• Support and enhance monitoring equipment for power, cooling, networking, storage, and compute resources.
• Troubleshooting, diagnosis, and fault isolation of system failures.
• Writing, modifying and maintaining programs for automated administration tasks.
• Work independently on important projects and assignments, with limited supervision, receiving general instructions.
• Exercise discretion and independent judgment to evaluate methods and resources, which will best accomplish assigned work, on time and within budget.
• Occasional travel to conferences or meetings.
• Other duties, as assigned.

Requirements & Qualifications

• BS degree or equivalent combination of education and experience with 2+ years experience in data center operations and 5+ years of computer systems administration.
• Excellent oral and written communication skills are essential, as is the ability to effectively communicate with all levels of management and other professionals.
• Strong background in Linux system administration and facilities operations.
• Proficiency administering core servers, computer clusters and storage systems running a variety of Operating Systems (e.g. RedHat, Ubuntu, Solaris) hosting a variety of services (e.g. Apache, LDAP, DNS, IMAP, NFS, SMTP).
• Familiarity with facilities design and operation, including knowledge of power and cooling systems.
• Working knowledge of languages and tools used by scientific applications (e.g. Python, Perl, Bash, SVN, Trac, C++, MPI, PBS, TotalView).
• Attitude and aptitude to learn quickly, high levels of initiative.
• Proactive, self-starter able to address complex issues effectively within a team environment and independently.
• BS degree in engineering or related field.
• Familiarity with high performance networking, cluster management and high performance file systems (e.g. GigE, InfiniBand, CMU/ACE/ROCKS, Panasas).
• Data center infrastructure upgrade participation.
• Experience in a university environment is highly desirable.

Caltech is an equal opportunity/affirmative action employer. Women, minorities, veterans and disabled persons are encouraged to apply.

The Center for Advanced Computing Research at the California Institute of Technology is seeking a highly motivated individual to engineer scientific software to make effective use of accelerators, particularly general-purpose graphics processing units (GPGPUs). There are applications in several research groups, including geophysics, solid mechanics, chemistry, and biology. The initial responsibility will be optimizing codes to exploit a large new hybrid (CPU/GPGPU) cluster in the Division of Geological and Planetary Sciences. Specific applications include Bayesian models of fault slip during large earthquakes, inverse models of the Earth’s interior structure, large-scale remotely sensed image processing and models for use in rapid tsunami early warning systems.
