HPC Software Engineer (Hybrid Eligible)

Requisition Id 13595 

Overview:    

We're hiring an HPC Software Engineer to support the integration of computing hardware and software tools for accomplishing research tasks across a variety of scientific research areas! This position is in the Emerging Technologies & Computing (ETAC) Group in the Research Computing Support Division (RCSD) of the Information Technology Services Directorate (ITSD) at Oak Ridge National Laboratory (ORNL).

Our HPC engineering team facilitates the mission of ORNL through HPC systems engineering, integration, and support for the research community at ORNL. By providing design, deployment, optimization, monitoring, and tooling support across multiple clustered infrastructures, we facilitate Lab-wide R&D projects. Our HPC clusters range in scope from just a handful of nodes to greater than fifty thousand cores.

What will you be doing? 

ETAC focuses on supporting ORNL researcher’s HPC computing, Data Engineering and Management, Infrastructure as a Service, and new technology needs. You'll be working directly with researchers, supporting their science and understanding scientific problems and the application of advanced research computing tools to help achieve research outcomes. The HPC Scientific software engineers play a crucial role in optimizing computational methods and facilitating groundbreaking research across multiple scientific areas. As an HPC team member, you will recommend computational and/or visualization tools, techniques, and methodologies for the scientific computing aspect of research investigations.

Major Duties/Responsibilities: 

• Scientific Software and Application Management:
  • Understand scientific software users’ requirements: work closely with researchers to understand their computational needs and translate them into efficient HPC applications. Analyze application performance to identify bottlenecks and develop strategies to improve scalability and efficiency on HPC systems. This may involve profiling code, analyzing communication patterns, and tuning system parameters.
  • Install and manage scientific software: deploy and maintain a wide range of scientific applications, libraries, and development tools on HPC systems to support research activities.
  • Develop custom tools and scripts: develop tools to automate common tasks, improve systems management, and facilitate sophisticated computational workflows. Develop, maintain, and install software for HPC and data intensive architectures, including Graphic Processing Units (GPUs), parallel systems, and other computing environments.
• User support and collaboration:
  • Provide software technical support: collaborate with HPC support and scientists on technical issues related to scientific software problems. Following industry standards, implement HPC software with novel programming and optimization techniques. Provide solutions and technical recommendations for code optimization, resource utilization, and system tuning.
  • Collaborate on research projects: work closely with researchers to understand their computational requirements and assist in developing efficient computational strategies, code optimization, and parallelization. This includes working with a highly diverse and multidisciplinary team (such as mathematicians, physicists, computer scientists, and engineers) in the research, development, integration, testing, and deployment of research software, data platforms, and machine learning systems for large-scale data analysis.
  • Research information dissemination: support research staff in disseminating results in peer-reviewed journals, technical reports, relevant conferences, and open-source software project repos.
• Research and development:
  • Stay informed about latest research in HPC and AI.
  • Develop and recommend ideas for new programs, products, and features by staying abreast of new technology developments and trends.
• Partnerships and collaboration:
  • As applicable/possible- establish and maintain partnerships and collaborations with industry, other groups at ORNL, and HPC networks to share knowledge and best practices.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service.
