Job description

Description
Job Title High Explosives Computational Physicist (Scientist 3)
Location Los Alamos, NM, US
Organization Name XCP-2/Eulerian Codes
Minimum Salary 128000
Maximum Salary 215900
This position is open for external candidates only to apply.
What You Will Do
The Eulerian Codes Group (XCP-2) is looking for exceptional candidates to develop, implement, and exercise high explosives models in our massively parallel multi-physics codes as part of the Advanced Scientific Computing (ASC) Program. XCP-2 staff span a wide range of computational physics modeling disciplines including 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. Other XCP-2 research efforts focus on the development and optimization of cutting-edge physics algorithms for performance on both homogeneous and heterogeneous high-performance computing platforms. 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.
What You Need
Minimum Job Requirements:

Technical Knowledge
Thorough professional knowledge, experience, and leadership in computational modeling of high explosives, reactive flow, or chemical kinetics.
Software Engineering & Design
Advanced proficiency with modern Fortran, C, or C++ and/or experience in the development of multi-physics scientific codes, including software engineering practices and user support.
Collaboration
Teamwork is essential to the success of our group. As such you will need to have demonstrated the 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.

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.
Education/Experience: 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.
High Performance Computing
It would be great if you have experience with massively parallel numerical development and simulation, and experience deploying numerical algorithms to heterogeneous computing architectures.
Mission Focus
Candidates that demonstrate experience with LANL's mission and research environment including impact on programmatic deliverables for the nuclear weapons program will be given preference.
Work Location: The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.
Position commitment: Regular appointment employees are required to serve a period of continuous service in their current position in order to be eligible to apply for posted jobs throughout the Laboratory. If an employee has not served the time required, they may only apply for Laboratory jobs with the documented approval of their Division Leader. The position commitment for this position is 1 year.
