Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2019 Best Places to Work by Glassdoor!

We have an opening for a High Performance Computing (HPC) Development Operations (DevOps) Storage Engineer. You will combine software development and systems engineering with a focus on extreme scale high performance storage that provides systems capable of storing billions of files and hundreds of petabytes. You will work with a small team of DevOps engineers and developers to help architect, deploy, and manage the High Performance Storage Systems (HPSS) that provide a reliable, massively-distributed, long-term archival system for storing our irreplaceable data. This position is in the Livermore Computing (LC) Division within the Computation Directorate.

Essential Duties
- Perform hardware/software deployments, upgrades, configuration, monitoring, management, performance tuning, and ongoing support of HPSS in LC production archives.
- Perform software design, development, testing, and deployment of HPSS client interfaces.
- Apply site reliability engineering/systems engineering practices to manage and improve one or more production aspects of HPSS.
- Develop and maintain tools and utilities that aid in the operation, automation, and reliability of software-based administrative tasks associated with LC production archives.
- Analyze and tune multiple aspects of the archival service (e.g. automated monitoring, database design, networks, large-scale disk and/or tape subsystems performance) to collaborate and develop new ideas, modify approaches, and/or redefine customer requirements that impact organizational operations or directions for our future systems.
- Independently troubleshoot, determine root cause, and fix highly complex storage system issues that may involve interfacing with various technical staff across multiple organizations with differing levels of knowledge and expertise.
- Lead the deployment of software releases, patching of the various subsystems, and third-party utilities with emphasis on overall system reliability, availability and serviceability.
- Provide 24/7 customer support as a member of a rotating call list in a fast-paced and mission-critical environment.
- Perform other duties as assigned.

Qualifications
- Bachelor’s degree in Computer Science or related field or the equivalent combination of education and related experience.
- Substantial experience with C, Java, Python, or Perl programming (or any high-level programming language), and/or common shell scripting environments (e.g. bash).
- Ability to engage with technical staff and end-users, requiring deep technical knowledge and critical thinking necessary to effectively work with members of the Data Storage Group, HPSS development community, other LC staff, LC end-users, and to represent the Laboratory publicly (e.g. user groups and technical conferences).
- Experience setting priorities, developing new ideas, modifying approaches, and solving highly complex problems with minimal guidance and using independent judgment in a fast-paced, rapidly changing, customer-focused team environment.
- Highly advanced skills performing Linux/UNIX or storage systems administration (including software installations, updates/patching, configuration management, system security, networking, storage allocation), and/or advanced knowledge of Linux/UNIX systems programming, kernel internals, large scale application/kernel debugging techniques, and/or software testing/quality assurance techniques.
- Substantial experience with software version control and configuration management systems such as Git, Subversion, CFEngine, Puppet, etc.
- Expert verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.
- Ability to work off-hours and on-call (intermittently either as needed or as part of a rotation).

Desired Qualifications
- Master’s degree in Computer Science or related field.
- Experience with high performance computing, large scale data centers, HPSS and/or other mass storage systems.
- Knowledge of one or more storage systems hardware components (e.g. Spectra Logic or Oracle robotics, Oracle/IBM tape drives, NetApp RAID, Qlogic HBAs, direct-attach fiber).

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  Q-level clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

Note:   This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
