Discover your future at Berkeley Lab!


Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC) Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC) has an opening for a Site Reliability Engineer. In this role, you will provide a variety of engineering support services in a 24x7 environment. You will work for the Operations Technology Group (OTG) and ensure that NERSC (a DOE computational facility) is accessible, reliable, secure and available to our scientific users. We support a community of more than 7,000 scientists who use NERSC computational resources to perform basic scientific research across a wide range of disciplines, including climate modeling, research into new materials, simulations of the early universe, analysis of data from high energy physics experiments, investigations of protein structure, and a host of other scientific endeavors.



What You Will Do:

  • Apply working knowledge of clustered Linux systems to manage the reliability of the NERSC facility in three areas: computation, data storage, and the facility environment, to enable the continuous scientific progress of the users.

  • Apply demonstrated skills as a Linux Systems Administrator and a site reliability engineer.

  • Work on and solve problems of diverse scope relating to maintaining critical services functioning, creating alerting, notification and problem-solving programs to prevent problem recurrence with the goal of automating the response to all routine service conditions.

  • Under the guidelines of the group’s project manager, collaborate with others in developing and maintaining diagnostic tools used to support the HPC community within NERSC using programming languages like C, C++, python, java or Perl using knowledge of standard software development practices.

  • Using knowledge of the Facility Operations processes, provide input in the design of software tools, workflows and new processes that continuously improve the diagnostic capabilities of the group to ensure the availability of the HPC services provided by NERSC.

  • Collaborate with other groups in the testing and implementation of new diagnostic tools, workflows and new capabilities for providing high availability for the systems in production. Write the documentation necessary for these new tools and provide training for staff in their use.

  • Provide accurate information in the trouble ticketing system for outages, maintenances and other incidents such that the workflow and protocols can be appropriately tracked by others.

  • Work closely in cooperation with other NERSC groups to manage maintenances, to perform tasks like upgrades, to shut down batch queues, and to manage diagnostic and notification software or generally manage a center­wide outage.

  • In cooperation with Lab Fire and Safety, play a primary role in investigating, assessing and confirming fire-related alarms to protect and minimize damage to the assets of the HPC floor.

  • Conduct periodic on­call duties as necessary to support a 24x7 workflow.

    This position supports a 24x7 operation. The current schedule requires a candidate to work the ​night shift, weekend hours and holidays depending on operational needs and a 24x7 on-call​ ​rotation.


What is usually Required:

  • Bachelor’s Degree in Computer Science or similar discipline and a total 5 years of​ ​experience; or an equivalent combination of education and experience.

  • Three years as a Linux (or similar type of operating system) system administrator or system engineer in a customer facing environment supporting data clusters, managing the replacement of hardware, and ensuring its continued availability to the user community. This can include assisting in the deployment of new nodes and internal switches into production, resolving ticket incidents and working with vendors on hardware warranty replacements.

  • Hands­​-​on experience in Red Hat Enterprise Linux or another Linux variant in a shell or command line environment.

  • Minimum of ​3​ years of experience in a UNIX or Linux environment with Networking, IT infrastructure environment or cluster management experience in a distributed computing environment.

  • Hands-on experience with developing tools using various programming languages such as C, C++, Perl, Java, and Python or a scripting language with knowledge of standard software development practices. Feel free to share your GitHub repository for us to look at.

  • Networking: experience with network theory such as TCP/IP, UDP, ICMP (networking protocols in general), MAC addresses, IP packets, DNS, OSI layers, and load balancing.

  • An understanding of the different monitoring implementations and the solution’s system administration.

  • Past experience with Incident Management and a proficient understanding of IT service management.

  • Exposure to Oracle or other high​ ​­end Storage Infrastructure.

  • Background configuring distributed, server­​ ​based or cluster­​ ​based infrastructure supporting a high volume of transactions in a Linux environment. An understanding of VM's and Containers, how to manage them and an understanding of the IoT technologies.

  • Knowledge of and ability to work on large data communications networks and IT infrastructure supporting highly available systems and applications.
    Demonstrated ability to deliver results on time with high quality.

  • Proficient oral and written communications skills. Collaborates well in a team environment.

  • Excellent problem-solving skills. Must be able to think independently, work collaboratively and contribute to the final resolution.

  • Must show good judgment and ability to schedule and lead a small group of people and/or projects.

  • Motivated, self-starter who can learn emerging technologies that improve data center management in areas like Jupyter, Kibana, Functions as a Service, Kubenetes, building management software, evaporative cooling, and power utilization.

Additional Desired Qualifications:

  • Experience with network security: configuring/maintaining ACLs, knowledge of firewalls

  • Network programming or a network certification.

  • A certification in a system administration area.

  • Be able to provide input toward creating new standards and methods for managing large scale distributed systems.

The posting shall remain open until the position is filled.


Notes:

  • This is a full time, 1-year term appointment with the possibility of extension or conversion to Career appointment based upon satisfactory job performance, continuing availability of funds and ongoing operational needs.

  • Work Schedule: Full-time, night shift, exempt (monthly paid) from overtime pay.
