HPC Storage Systems Developer

Lawrence Berkeley National Lab's (LBNL) NERSC Division has an opening for a HPC Storage Systems Developer to join the team.

NERSC is looking for a skilled systems programmer to help develop innovative software features for extreme-scale storage systems. In this position, you will join the Storage Systems Group which is made up of system engineers and programmers providing NERSC's 300 petabyte High Performance Storage System and center-wide file systems. Our storage systems are utilized by more than 8,000 scientists who use NERSC to perform unclassified, scientific research across a wide range of disciplines, including climate modeling, research into new materials, simulations of the early universe, high energy physics and a host of other scientific endeavors. The majority of your time will be spent developing, testing and deploying storage systems software, tools and scripts, but you should be flexible and willing to take on troubleshooting and system administration tasks in support of our production environment.

In this exciting role, you will work with a team of software engineers who develop the High Performance Storage System (HPSS) and supporting software. HPSS is a premier high-performance archive software and is deployed at some of the world's largest computing centers to meet the most challenging long-term and scalable-storage requirements. Jointly developed by five Department of Energy labs and IBM, you will collaborate daily with this geographically distributed team, taking on a variety of development tasks. The storage applications and features you create will become part of our production storage systems, and will be used by HPSS sites around the globe, including our production storage systems at NERSC. In addition to working on HPSS releases, you will also assist with supporting the production version of the software and its local applications at NERSC.

In addition to working on HPSS, you will help evaluate and shape new storage technologies to meet the evolving needs of NERSC's high-performance computing users, and work on local development projects to improve the storage resources we offer. This includes exploration of object-based storage systems, advanced high-performance data transfer tools, implementation improvements for automated data migration between file systems and the archive, and evaluation of storage software built using new storage hardware technologies.

What You Will Do:

• Participate as a software developer in the HPSS collaboration.
• Assist with keeping the HPSS software and tools available and working well for users.
• Work independently or with the team to diagnose and fix production system problems, analyze system issues, and develop workarounds and/or patches for software bugs.
• Collaborate with other groups on efforts to improve data management and movement.
• Define and lead team-oriented agile development and management processes.
• Design and implement new software features.
• Support, maintain, and upgrade code and patches.
• Provide software support and assistance to system administrators on the team.
• Improve automated build, test, and deployment portions of the software lifecycle.
• Iteratively design, code, review, and debug as part of a collaborative development process.
• Write or maintain architecture, design, and user documentation.
• Present your work and represent NERSC at conferences and meetings.
• Help drive software requirements, ensuring that NERSC needs are represented.
• Provide leadership and technical guidance to group members and members of other groups at NERSC.
• Develop documentation such as LBNL technical reports and design documents.
• Influence and introduce new technologies or functionality.
• Represent NERSC and NERSC's interests in the HPSS community.
• Present your work and represent NERSC at conferences and meetings.

What is Required:

• Bachelor of Science degree in Computer Science, Computer Engineering or equivalent experience and a minimum of 8 years of software development experience in a UNIX or Linux environment.
• Strong C/C skills and python/shell programming skills.
• Demonstrated expertise with data structures used in a typical Unix filesystem.
• Systems programming in a Unix environment.
• Experience with multi-threaded programming.
• Ability to resolve complex issues in creative and effective ways.
• Ability to network and collaborate with key contacts outside their own area of expertise.
• Excellent oral and written communication skills.
• Demonstrated ability to work effectively as part of a cross-disciplinary team.

Desired Qualifications:

• Experience with cloud technologies and computing.
• Experience with microservices development and deployment.
• Prior work administering or developing HPSS or other production grade hierarchical storage or file system.
• Experience writing high performance data transfer applications.
• Experience with tape storage hardware and software.
