Job description

Overview

The Eulerian Codes Group (XCP-2) is looking for exceptional candidates to develop and optimize cutting‑edge algorithms for massively parallel multi‑physics codes on heterogeneous high‑performance computing platforms. XCP‑2 staff span a wide range of computational physics disciplines, including software engineering, numerical fluid and solid mechanics, materials science, radiation hydrodynamics, plasma physics, turbulence, magnetohydrodynamics, high explosives, nuclear physics and engineering, and neutral and charged particle transport. The duties of our well‑compensated professionals include research and development of applied physics and engineering models, the implementation of these methods into production codes using excellent software development practices, the testing and validation of these methods, and the education and support of users as they adopt these methods.

Qualifications

• Demonstrated advanced‑level expertise and leadership experience in software modernization and performance optimization.
• Proven expertise in developing and implementing massively parallel numerical simulations, with demonstrated experience deploying numerical algorithms across heterogeneous computing architectures.
• Recognized proficiency with modern C++. Applicants with experience in Fortran and C languages and the development of multi‑physics scientific codes, including software engineering practices and user support, will be given preference.
• Teamwork experience; ability to function effectively in a team environment, willingness to learn new skills, and flexibility in work assignments.
• Experience mentoring students, postdocs, or more junior staff.
• Proven track record of securing and expanding funding for small to medium‑sized projects, with experience leading such projects from inception to completion.
• Master’s degree in a STEM field and 6 years of relevant experience or an equivalent combination of education and experience.
• Preferred: Master of Science degree in Applied Mathematics, Physics, Engineering, or a closely related discipline.
• Proficiency in advanced C++ techniques (template metaprogramming, compile‑time programming) and strong knowledge of C++ standards.
• Experience working within LANL’s research environment and demonstrated impact on nuclear weapons program deliverables is strongly preferred.
