Location: ESnet Burkely Lab, Bay Area, California, United States
ESnet at Berkeley Lab is hiring for a Network Performance Postdoctoral Fellow to help improve global scale data transfer performance.
ESnet provides the high-bandwidth, reliable connections that link scientists at national laboratories, universities and other research institutions, enabling them to collaborate on some of the world’s most important scientific challenges. Funded by the Department of Energy (DOE) Office of Science, and managed and operated by the ESnet team at Berkeley Lab, ESnet provides scientists with access to unique DOE research facilities and computing resources.
A key ongoing area of technical investigation relates to the effective use of ultra-high-speed networks to transfer huge quantities of data on a global scale from the site of acquisition such as the Vera C. Rubin Observatory in Chile to processing sites on distant continents. To address these challenges, ESnet has recently embarked on an NSF funded project with partners at Florida International University to explore the use of temporal network state information as a basis for dynamically tuning end hosts transfer protocols to achieve better transfer performance.
We are seeking a Postdoctoral Fellow for Q-Factor to participate in the research and development of real-time network telemetry systems, and TCP congestion control tuning. In this role you will perform software development, conduct empirical assessment of techniques and publish results in collaboration with ESnet staff and external participants in efforts to improve global scale data transfer performance that will enable future network services and scientific workflows.
What You Will Do:
- Contribute to research and development on the NSF Q-Factor project.
- Implement systems that analyze network telemetry in real-time and perform actions on selected events.
- Conduct research on TCP congestion control tuning using precision network telemetry.
- Perform extensive network measurements on the ESnet testbed.
- Document work and results in the form of journal papers and conference proceeding papers, and present work and results at scientific meetings.
- Collaborate with other computer scientists, system engineers and our project partners at Florida International University.
What is Required:
- PhD degree in Computer Science or related fields or an equivalent combination of education and experience.
- Demonstrated expertise and understanding of common network protocols (e.g., TCP, UDP).
- Demonstrated experience in performance analysis of computer networks.
- Demonstrated creativity and the ability to perform independent research on computer networks and systems.
- Knowledge of low-level system programming languages (such as C, Go or Rust).
- Demonstrated ability to work effectively as part of a cross-disciplinary team.
- Knowledge of declarative and functional languages.
- Use of data plane programming and associated architectures and languages (e.g., P4).
- This is a full-time 1 year, 9 month, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than 4 years of paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
- This position is represented by a union for collective bargaining purposes.
- Salary will be predetermined based on postdoctoral step rates.
- This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
- This position has the option of working remotely.
