About Jefferson Lab Join a community with a common purpose of solving the most challenging scientific and engineering problems of our time. The Jefferson Lab campus is located in southeastern Virginia amidst a vibrant and growing technology community. A career at Jefferson Lab is more than a job. You will be part of “big science” and work alongside top scientists and engineers from around the world unlocking the secrets of our visible universe. Managed by Jefferson Science Associates, LLC, Thomas Jefferson National Accelerator Facility is entering an exciting period of mission growth and is seeking new team members ready to apply their skills and passion to have an impact. You could call it work, or you could call it a mission. We call it a challenge. We do things that will change the world. What your job will be like: The Jefferson Lab Scientific Computing Department, within the Computational Sciences and Technology (CST) division, is seeking applicants with extensive experience in the area of Computational Physics and high-performance computing (HPC). The successful candidate will closely interact with members in the Scientific Computing department and researchers from the Theory Center to support critical research programs in Lattice Quantum Chromodynamics (LQCD) calculations, and to contribute to program development in advanced computing for Nuclear Physics and Computational Science. 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).In this job you will:

• Conduct research and development in lattice QCD (LQCD) methods, focusing on architecture‑specific performance optimization for high‑performance computing systems at DOE Leadership Computing Facilities.
• This includes designing and implementing efficient, state‑of‑the‑art numerical algorithms and integrating them seamlessly 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.Experience
