DESCRIPTION The Mission of the San Diego Supercomputer Center is to translate innovation into practice. SDSC adopts and partners on innovations in industry and academia in the areas of software, hardware, computational and data sciences, and related areas, and translates them into cyberinfrastructure that solves practical problems across any and all scientific domains and societal endeavors. Cyberinfrastructure refers to an accessible, integrated network of high-performance computing, data, and networking resources and expertise, focused on accelerating scientific inquiry and discovery. With more than 250 employees and $30-50M of revenue a year, SDSC is a global leader in the design, development, and operations of cyberinfrastructure. SDSC supports hundreds of multidisciplinary programs spanning a wide variety of domains, from earth sciences and biology to astrophysics, bioinformatics, and health IT. SDSC presently operates multiple large HPC systems ranging from a 120k x86 CPU core general purpose system to a system explicitly designed for Artificial Intelligence and Machine Learning, and a nationally distributed system open for all of academia to integrate with. SDSC offers research data services across the entire vertical stack from universally scalable storage to consulting services on FAIR, Big Data, and AI. SDSC offers a rich set of cloud services both on-premise, in the commercial cloud, and as hybrid services across both. SDSC has three geographic scopes, a national scope supporting cyberinfrastructure for the entire US research and education community, a California scope with a special focus on convergence research that addresses the three dominant threats to CA: Drought, Fire, Earthquakes, and a campus scope focusing on advancing the global impact of SDSC by advancing the research objectives of the UC San Diego faculty, researchers, and students. SDSC impacts researchers at scales from 1,000’s to Millions. SDSC annually trains thousands of researchers in cyberinfrastructure tools and software, and supports thousands of individual researchers via Unix accounts on its large HPC systems. SDSC was a leader developing the Science Gateway concept, and continues to be a global leader in its evolution. SDSC operates multiple major such gateways with user communities ranging from the tens of thousands to the millions. SDSC’s educational programs includes online courses that have been attended by more than a million students. SDSC is committed to democratizing access to cyberinfrastructure across all of its geographic scopes. SDSC strives towards a culture that supports our employees to be their best, achieve their goals, and enjoy their lives, both professionally and personally. The Center for Applied Internet Data Analysis (CAIDA) is an independent analysis and research group based at the University of California's San Diego Supercomputer Center. CAIDA investigates both practical and theoretical aspects of the Internet, with particular focus on topics that are macroscopic in nature and provide enhanced insight into the function of Internet infrastructure worldwide, improve the integrity of the field of Internet science as well as the integrity of operational Internet measurement and management, and inform science, technology, and communications public policies. The Systems and Network Administrator will apply skills as an experienced systems infrastructure professional with a strong understanding of Internet infrastructure measurement opportunities: Border Gateway Protocol (BGP) routing, Domain Name System (DNS), and an understanding of industry best practices in these areas for the Center for Applied Internet Data Analysis (CAIDA) program at UCSD/SDSC. They will design, deploy, manage, enhance, maintain and document large-scale data and compute solutions, including computer systems, networking, security, and writing and executing of complex scripts to build and sustain the infrastructure that supports Internet measurement research with evolving cybersecurity and networking needs. They will also design and implement continuous integration/deployment workflows with Ansible infrastructure-as-code (IaC), selectsand design, implement and automate processes such as vantage point onboarding and outage notifications; and selects big data systems like Apache Kafka for large-scale analysis to facilitate security research use of large data archives. Also, the incumbent will perform simple to moderate cost/benefit analyses in the development of measurement instrumentation and data capture, management, processing, and dissemination systems; as well as develop, implement, and deploy virtualization solutions for measurement and analysis software capabilities. The incumbent will also build dashboards to aggregate and correlate usage statistics across data sets and time, manage external requests (e.g., BGP peering), deploy new vantage points with IPv6 support, resolve connectivity issues, migrating collectors to virtual machines, and maintain monitoring through alerts, access controls, and Grafana dashboards. The Systems and Network Administrator will also create new metadata and schemas for existing community data sets, including for integration of data into cloud platform technologies as well as enable cloud-based data access, develops schemas for BGP data, and supports compute/storage clusters for Internet Health Report activities. Additionally, the incumbent will perform complex security control activities through firewalls and permissions, maintains hardware/software inventories and vantage point databases, produces internal and public-facing documentation, and tracks usage statistics as well as manage community software issues and task prioritization based on community workshops and meetings. They will also provide user support through ticketing systems, develop virtualization solutions, manage community software priorities, and architect metadata and schemas for integrating community data sets into cloud platforms—combining technical expertise with outreach to the broader research community.
