The School of Engineering

Stanford Engineering has been at the forefront of innovation for nearly a century, creating pivotal technologies that have transformed the worlds of information technology, communications, health care, energy, business and beyond. Our faculty and students are creative risk-takers who pursue excellence across a breadth of disciplines. Our alumni include some of the world's most successful leaders in technology and business. Our staff are critical to enabling Stanford Engineering to accomplish its mission: seeking solutions to some of the world's most urgent challenges and educating leaders who will make the world a better place through the power of engineering principles, techniques and systems. 

The Stanford Data Science Initiative. The Stanford Data Science Initiative (SDSI), founded in 2014, has worked to provide researchers with new technologies and resources. Now in its fourth year, SDSI is proud to be the foundation of Stanford University's major and expanded new efforts to develop a campus wide Data Science ecosystem. SDSI aims to make Stanford a data enabled university. The Initiative advances data science methods and tools, and weaves them into the fabric of the university, to effectively respond to our most pressing societal and scientific challenges. The initiative works to support research in a variety of fields where incredible advances are being made through the facilitation of meaningful collaborations between domain researchers, with deep expertise in societal and fundamental research challenges, and methods researchers that are developing next generation computational tools and techniques.

The System Administrator 2 will support the members of the Stanford Data Sciences Initiative (SDSI) and the Infolab research lab in the Computer Science department. The main role is to interact and consult with students, professors and research staff on a daily basis and to tune, configure, develop, and propose novel system infrastructure designs that will support and advance the lab members’ research in the area of large graph computations, scalable machine learning algorithms, information extraction pipelines, and information management.

Your responsibilities include:

  • System support for large-scale processing: configuring compute clusters, tuning resource managers, supporting massively parallel job execution, optimizing kernel for CPU and GPU bound jobs, optimizing cluster network connections, support infrastructure scale-out, extending in house capabilities with cloud offerings, supporting, installing and optimizing CUDA and other co-processor technologies.
  • System support for massive in-memory graphs and databases: configuring CPU core affinities, configuring IRQ affinities, supporting development of NUMA aware code, configuring fast server to server and server to storage interconnects, tuning kernel and network.
  • System support for large-scale data storage: configuring storage systems, backup, supporting eventually consistent storage, configuring HA storage systems, configuring and monitoring multi-stage backup, managing real time replication with data streaming, designing petabyte storage systems.
  • System performance tuning for big memory machines: optimizing kernel, building custom kernels, NUMA aware software development, in-depth resource usage tracking.
  • Strategic large-scale infrastructure development: designing a petabyte storage system, designing clusters with large-scale memory nodes, designing clusters for large-scale computing, designing massively parallel data access systems, planning new compute clusters.
  • System support for large-scale crawling: supporting web crawling from a large amount of parallel clients, virtualization of resources, network configuration and network rate limiting, designing intelligent crawling systems.
  • Consulting with researches: daily interaction with the Infolab group’s researchers, designing novel system architecture to support experiments, optimizing system resource usage, in depth resource usage monitoring, building custom kernels, optimizing kernel experiments, building support scripts, tracking down bugs, designing multi tier distributed systems, following group members’ research, participating in research meetings, building custom software packages, solving technical issues when running complex experiments, communicating with researches about their computing needs, planning experiment runs, helping researches with the available infrastructure, advising on best practices to run experiments, resolve issues during experiment runs, monitoring of experiment execution, combining existing infrastructure in new ways to facilitate experiments. 

To be successful in this position, you will bring: 

  • Bachelor's degree and five years of relevant experience, or a combination of education and relevant experience.
  • Deep knowledge about Linux server configuration and performance optimization, Linux kernel configuration and Intel and GPU processors, advanced knowledge of the following desktop operating systems: Ubuntu GNU/Linux, CentOS GNU/Linux, Windows and Mac OS X, experience with configuration management and  system monitoring tools, experience with software packaging on Linux, MacOS and Windows.
