High Performance Computing Software Engineer (Scientist 3)

About the Role

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.

Requirements

• Technical Knowledge: Demonstrated advanced-level expertise and leadership experience in software modernization and performance optimization.
• High Performance Computing: Proven expertise in developing and implementing massively parallel numerical simulations, with demonstrated experience deploying numerical algorithms across heterogeneous computing architectures.
• Software Engineering & Design: 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.
• Collaboration: Teamwork is essential to the success of our group. Demonstrated ability to function effectively in a team environment with a willingness to learn new skills and be flexible in work assignments. This includes exhibiting professional conduct in interactions with co-workers and supervisors.
• Mentorship: Experience mentoring students, postdocs, and/or more junior staff.
• Funding & Project Management: Proven track record of securing and expanding funding for small to medium-sized projects, with demonstrated experience successfully leading such projects from inception to completion.

Qualifications

Position requires a Master's degree in a STEM field from an accredited college or university and 6 years of relevant experience or an equivalent combination of education and experience directly related to the occupation.

Desired Qualifications

• Master of Science degree in Applied Mathematics, Physics, Engineering, or closely related discipline preferred.
• C++ Expertise: Proficiency in advanced C++ techniques (template metaprogramming, compile-time programming) and C++ standards knowledge strongly preferred.
• Mission Focus: Experience working within LANL's research environment and demonstrated impact on nuclear weapons program deliverables strongly preferred.

Clearance

This position requires a Q clearance, which requires U.S. citizenship except in extremely rare circumstances. Selected applicants will be subject to a background investigation and must meet eligibility requirements for access to classified matter. Dependent upon the position, additional authorization to access classified information may be required, which may or may not be available to dual citizens.
