This position provides excellent opportunities for career development in both physics and computer/computational science in a world leading research establishment, further enhanced by the upcoming High Performance Data Facility (HPDF).

• Carry out research and development in the areas of LQCD calculations with emphasis on architecture specific performance optimizations targeting high performance computing architectures at DOE's Leadership Computing Facilities and Supercomputers as well as on efficient implementations of novel numerical algorithms that can be integrated into the existing LQCD software stack
• Participate and support the computational campaigns of the Theory Center including software development, building and deployment both on local and remote computing resources
• Design and develop AI agentic HPC workflows to automate scientific discovery across geographically distributed computing locations
• Utilize Model Context Protocol (MCP) to create autonomous fabrics between scientific models and distributed infrastructure
• Evaluate emerging computing architectures to contribute future hardware acquisition and strategy

• Bachelor's Degree in Theoretical Physics, Computational Science, or Computer Science

• 3 or more years' experience working on high performance computing projects

• Demonstrated knowledge of computer algorithms relevant to the computational domain. Experience of efficient implementation of some of these algorithms targeting specific computing architectures
• Proficient in C or C++ along with scientific Python computing stack
• Experienced with modern development methods and tools
• Preference will be given to candidates who have extensive knowledge and experience in the following areas:
  Developing parallel software using OpenMP and MPI. Heterogeneous computing using CUDA/ROCm, or OneAPI/SYCL. MCP (Model Context Protocol) and who are highly proficient in navigating complex HPC job scheduling systems such as SLURM. Experienced in Agentic AI Framework such as Lang Graph
• Excellent verbal and written communication skills are essential

• Ph.D. in Theoretical Physics, Computational Science, or Computer Science
• Research background in computational LQCD and knowledge in agentic AI
